Abstract
Purpose: To assess long-term visual and neurodevelopmental outcomes in children with congenital Zika syndrome (CZS) after strabismus surgery. Methods: A consecutive sample of five children with CZS who underwent strabismus surgery was enrolled. All children underwent a standardized pre- and postoperative protocol including binocular best-corrected visual acuity (BCVA) using the Teller Acuity Cards II (TAC II), ocular alignment, functional vision using the functional vision developmental milestones test (FVDMT), and neurodevelopmental milestone evaluation using the Bayley Scales of Infant Development-Third Edition (BSID-III). Scores of the FVDMT outcomes considering the child's developmental age based on the BSID-III score were compared with scores from postoperative assessment. Results: Five children with CZS (3 girls, 2 boys) were enrolled with a mean age at baseline (preoperative) of 35.0 ± 0.7 months (range, 34-36 months) and at final assessment of 64.4 ± 0.5 months (range, 64-65 months). Preoperative BCVA was 1.2 ± 0.5 logMAR and at final assessment 0.7 ± 0.1 logMAR. Successful strabismus surgery outcome was maintained in 4/5 (80.0%) of children at final assessment. The children's BSID-III scores showed significant neurodevelopment delay at the initial assessment (corresponding developmental mean age was 4.7 months) and at their final assessment (corresponding developmental mean age was 5.1 months). There was improvement or stability in 34/46 items evaluated in the FVDMT (73.9%) when comparing baseline with 2-year follow-up. Conclusions: Strabismus surgery resulted in long-term ocular alignment in the majority of children with CZS. All the children showed improvement or stability in more than 70.0% of the functional vision items assessed. Visual and neurodevelopmental dysfunction may be related to complex condition and associated disorders seen in CZS including ocular, neurological, and skeletal abnormalities.

Anterior clinoid meningiomas: surgical results and proposed scoring system to predict visual outcomes. J Neurosurg 2024; 140:1295-1304. [PMID: 37922544 DOI: 10.3171/2023.8.jns23894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 08/22/2023] [Indexed: 11/07/2023]
Abstract
OBJECTIVE The authors report a single-surgeon experience with anterior clinoid meningiomas (ACMs) and propose a novel scoring system to predict visual outcomes based on preoperative risk factors. METHODS A cohort study of all ACMs that were surgically treated by a single surgeon between 2003 and 2021 was performed. Visual function was assessed by an ophthalmologist pre- and postoperatively. Based on the combination of visual fields and visual acuity, 4 visual grades were described. Favorable visual outcomes were defined as mild visual deficit or intact vision postoperatively. Unfavorable visual outcomes were defined as a severe or moderate visual deficit. Predictors of unfavorable visual outcomes were identified using multivariable logistic regression analysis. A scoring system was then created using the resulting β coefficient. A receiver operating characteristic curve analysis was performed to identify a cutoff point on the grading score for stratifying patients at risk for unfavorable visual outcomes. RESULTS Fifty-two patients met all inclusion criteria. Twenty-five (48%) patients presented with intact vision, and 27 (51%) presented with some visual dysfunction. Postoperative favorable visual outcomes were achieved in 39 patients (75%). Among the 27 patients presenting with visual dysfunction, 14 (52%) experienced improvement after surgery. No new visual deficits were observed among the 25 patients with intact vision at baseline. Nine patients (17%) had a reversible complication. Multivariable analysis showed that severe preoperative visual deficit (OR 13.03, 95% CI 2.64-64.39; p = 0.002), radiographic evidence of optic nerve (ON) encasement (OR 4.20, 95% CI 1.06-16.61; p = 0.04), intraoperative evidence of ON invasion (OR 17.31, 95% CI 2.91-102.86; p = 0.002), an average ganglion cell layer thickness of ≤ 70 µm (OR 21.54, 95% CI 2.94-159.04; p = 0.003), and an average retinal nerve fiber layer thickness of ≤ 80 µm (OR 13.68, 95% CI 1.91-98.00; p = 0.009) were associated with unfavorable visual outcome. The predictive score included the following factors: abnormal optical coherence tomography (OCT) findings, radiographic evidence of ON encasement by the tumor, and severe preoperative visual deficit. A score ≥ 4 of 6 points was demonstrated to be the cutoff associated with unfavorable visual outcome, with a sensitivity of 80%, specificity of 88%, positive predictive value of 80%, negative predictive value of 88%, and area under the curve of 0.847 (95% CI 0.674-1.0; p = 0.003). CONCLUSIONS The authors have designed a practical and novel scoring system to predict visual outcomes in patients with ACMs. This scoring system may guide preoperative discussions with patients and timely surgical intervention to yield optimal visual function outcomes. Although most patients have excellent neurosurgical outcomes, severe baseline visual deficits, ON encasement, and characteristic OCT abnormalities are associated with unfavorable visual function after ACM resection.

Clinical Characteristics of m.11778G>A Leber Hereditary Optic Neuropathy with Favorable Outcomes. Semin Ophthalmol 2024; 39:320-323. [PMID: 38420942 DOI: 10.1080/08820538.2024.2323114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Accepted: 09/26/2022] [Indexed: 03/02/2024]
Abstract
The prognosis of 11,778 mitochondrial mutations in Leber hereditary optic neuropathy (LHON) is poor. Patients with favorable outcomes (visual acuity better than 20/100) who could be observed for more than 6 months were analyzed. Among 74 patients (57 male, 17 female), 6 (8.1%) showed improvement in visual acuity of 20/100 or higher. The patients with favorable outcomes have better visual acuity at nadir (logMAR 0.98 ± 0.69 in the favorable patients and logMAR 2.32 ± 0.93 in the unfavorable patients, p = .003). Among the favorable group, four patients (36, 32, 19, and 7 years of age at onset) took idebenone within 6 months of onset. However, fifty-one percent of the patients with unfavorable outcomes took idebenone (p = .008). Although the age at onset in the favorable patients is relatively younger than that of the unfavorable patients (20.3 ± 10.8 versus 28.8 ± 12.8 years), a significant difference was not found (p = .138). In conclusion, better visual acuity in nadir and administration of idebenone may affect vision recovery.

Abstract
AIMS The aims of this study are to investigate the etiology, microbiological spectrum, and risk factors associated with visual outcomes of fungal endophthalmitis (FE) in a tertiary eye specialty hospital in Shanghai, China. METHODS This was a retrospective, single-center case series. The clinical characteristics, etiology, microbiological spectrum, and management, as well as the visual outcomes, were analyzed. Logistic regression was used to analyze the factors related to visual outcomes. RESULTS This study involved 102 eyes of 92 patients with FE, including 63 males (66.3%). The mean age was 44.4 ± 19.8 years. The most common etiology of FE was trauma (56.5%). The predominant fungal species isolated were Aspergillus spp. (31/93, 33.3%). Pars plana vitrectomy (PPV) and intravitreal antifungal agents was performed initially in 86 (84.3%) and 83 (81.4%) eyes, respectively. Only 35 (34.3%) eyes achieved final best corrected visual acuity (BCVA) of 20/400 or better. Ten (9.8%) eyes had a final BCVA of light perception or worse, and five (4.9%) had to be enucleated. The factors determining better visual outcomes included initial visual acuity better than finger-counting (FC) (odds ratio (OR) 5.811, p = 0.036), the absence of corneal infiltrate (OR 10.131, p = 0.002), and Candida species infection (OR 6.325, p = 0.011). CONCLUSIONS Early diagnosis of FE and a timely vitrectomy, combined with an intravitreal injection of an antifungal drug, can mitigate the devastating results of intraocular fungal infection. Not being infected by Aspergillus spp., an initial BCVA that was no worse than FC, and the absence of corneal involvement were related to better visual prognosis.

Risk-benefit analysis of surgical treatment strategies for cystic craniopharyngioma in children and adolescents. Front Oncol 2024; 14:1274705. [PMID: 38292926 PMCID: PMC10825040 DOI: 10.3389/fonc.2024.1274705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 01/02/2024] [Indexed: 02/01/2024] Open
Abstract
Objective Treatment strategies for craniopharyngiomas are still under debate particularly for the young population. We here present tumor control and functional outcome data after surgical treatment focusing on stereotactic and microsurgical procedures for cystic craniopharyngiomas in children and adolescents. Methods From our prospective institutional database, we identified all consecutive patients less than 18 years of age who were surgically treated for newly-diagnosed cystic craniopharyngioma between, 2000 and, 2022. Treatment decisions in favor of stereotactic treatment (STX) or microsurgery were made interdisciplinary. STX included aspiration and/or implantation of an internal shunt catheter for permanent cyst drainage. Microsurgery aimed for safe maximal tumor resections. Study endpoints were time to tumor recurrence (TTR) and functional outcome including ophthalmological/perimetric, endocrinological, and body-mass index (BMI) data. Results 29 patients (median age 9.9 yrs, range 4-18 years) were analyzed. According to our interdisciplinary tumor board recommendation, 9 patients underwent stereotactic treatment, 10 patients microsurgical resection, and 10 patients the combination of both. Significant volume reduction was particularly achieved in the stereotactic (p=0.0019) and combined subgroups (p<0.001). Improvement of preoperative visual deficits was always achieved independent of the applied treatment modality. Microsurgery and the combinational treatment were associated with higher rates of postoperative endocrinological dysfunction (p<0.0001) including hypothalamic obesity (median BMI increase from 17.9kg/m2 to 24.1kg/m2, p=0.019). Median follow-up for all patients was 93.9 months (range 3.2-321.5 months). Recurrent tumors were seen in 48.3% and particularly concerned patients after initial combination of surgery and STX (p=0.004). In here, TTR was 35.1 ± 46.9 months. Additional radiation therapy was found indicated in 4 patients to achieve long-lasting tumor control. Conclusion In children and adolescents suffering from predominantly cystic craniopharyngiomas, stereotactic and microsurgical procedures can improve clinical symptoms at low procedural risk. Microsurgery, however, bears a higher risk of postoperative endocrine dysfunction. A risk-adapted surgical treatment concept may have to be applied repeatedly in order to achieve long-term tumor control even without additional irradiation.

Abstract
INTRODUCTION This study was conducted to describe the epidemiology, prognostic factors, and visual outcomes of open globe injuries (OGIs) at a tertiary care centre in Western Rajasthan, India. METHODS Data of OGI patients treated at the Department of Ophthalmology, All India Institute of Medical Sciences, Jodhpur, Rajasthan, from March 2019 to December 2021 were reviewed retrospectively. Demographic details including age, gender, place of injury, wound characteristics (i.e., cause, mechanism, location, and size), visual acuity (VA), and associated ocular injuries were recorded. The Ocular Trauma Classification System (OTCS) and the Birmingham Eye Trauma Terminology (BETT) were used to categorize OGIs. All the data was entered into a Microsoft Excel sheet (Microsoft Corporation, Redmond, Washington, United States) and analyzed with IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States). RESULTS A total of 40 patients with OGIs were included. OGI was discovered to be four times higher in males and 47.5% of the total cases were observed in patients aged 0-15 years, followed by patients aged 16-30 (27.5%). The rupture injury showed a higher incidence rate (32.5%) than the penetrating injury (62.5%). Of all OGIs, 75% were grade 4 injuries, with zone 1 being the most often affected zone and wood stick injury being the most prevalent aetiology. A significant difference was noted (p<0.001) in comparing presenting VA with final VA with paired sample t-test. A negative Spearman correlation was noted between age and final VA (r = 0.53, p = 0.000), and the grade of injury and final VA (r = 0.51, p = 0.001.) Conclusion: Young males were the most susceptible group to sustain OGIs due to their more physical activities. Health education and safety in the workplace and during sports are crucial to reduce the incidence of OGI.

The effect of patient symptom awareness on the visual outcome in retinal detachment. Acta Ophthalmol 2023. [PMID: 38009800 DOI: 10.1111/aos.15815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 10/30/2023] [Accepted: 11/06/2023] [Indexed: 11/29/2023]
Abstract
PURPOSE To explore whether a patient's prior knowledge of the symptoms associated with rhegmatogenous retinal detachment (RRD) relates to the visual outcome after treatment. METHODS We performed a prospective survey study on 126 patients receiving treatment for primary RRD between March and July 2021. RESULTS Thirty-seven per cent (n = 47) of patients responded that they were aware of the RRD symptoms prior to the detachment. A history of RRD in the fellow eye or knowledge of family members treated for RRD was frequently reported as a reason for the patient's awareness of RRD symptoms. Patients aware of RRD symptoms presented significantly more often with an attached macula (χ2 , p = 0.002) and a better visual outcome following surgery (Mann-Whitney U, p = 0.028) compared to patients who were not aware of RRD-related symptoms. Among 76 patients with a myopic refractive error, only 15% (n = 11) indicated that they had been warned about the increased RRD risk related to myopia, suggesting that three-quarters of patients were not actively informed by their eye care professionals. CONCLUSION RRD symptom awareness is significantly related to a higher rate of macula-on RRDs and better visual outcomes after treatment. There is limited awareness of increased RRD risk in myopic RRD patients. These findings suggest that counselling individuals at high risk of RRD about related symptoms is inadequate and better counselling may improve visual outcomes following RRD treatment.

Abstract
Background Cataract is the leading cause of blindness and the second leading cause of visual impairment worldwide, accounting for 51% and 33% of all cases, respectively, in low- and medium-income countries bearing a disproportionately high burden. Hence, this study aimed to assess the visual outcome of age-related cataract surgery and identify factors associated with patients' postoperative visual outcomes in Jimma University Medical Center, Southwest Ethiopia. Methods An institution-based cross-sectional study design was conducted among 386 cataract surgery patients from January 1, 2016, to December 30, 2017. The study participants were selected using a systematic random sampling technique. Data were collected by reviewing the selected patients' medical records using a pre-tested checklist, entered into EpiData version 3.1, and exported to SPSS 20 for analysis. Proportions, summary statistics, and tables were used for presentations of the findings. Binary logistic regression was carried out to identify independent predictors of visual outcome. Findings were presented with adjusted odds ratios and their 95% confidence interval. A p-value <0.05 was used to declare a statistically significant association. Results About 231 individuals (59.8%) had poor visual results following cataract surgery. Furthermore, age >70 (AOR = 3.64; 95% CI [1.35-9.82]), preoperative ocular co-morbidities (AOR = 2.34; [1.32-4.15]), incision-based cataract surgery (AOR = 7.11; [3.16-16.02]), compared phacoemulsification operated by resident surgeons (AOR = 2.19; [1.23-3.89]), presence of intraoperative complication (AOR = 3.41; [1.47-7.92]), lens remnant (AOR = 2.91; [1.11-4.92]), ocular inflammation (OR = 2.56; [1.34-4.92]), and striate keratopathy/corneal edema (AOR = 1.91; [1.07-3.44]) were significantly associated with poor visual outcome. Conclusion The visual outcome following cataract surgery fall below WHO recommendation. In this study, age, ocular co-morbidities, surgical method, surgeon status, intraoperative complication, SK, and ocular inflammation associated with post-operative Uveitis and anterior chamber reaction were associated with a poor visual outcome.

Abstract
PURPOSE The purpose of the current study was to evaluate the prevalence of residual amblyopia in adults in a population screened and treated in childhood. We also wanted to evaluate the association of amblyopia on school success, level of education, and quality of life. METHODS This is a follow-up study of 2708 subjects of the Northern Finland Birth Cohort. At the age of 46, the subjects took part in ophthalmic examinations, including the measurement of best-corrected visual acuity (BCVA) and refraction. Residual amblyopia was defined as BCVA 20/30 or less (logMAR ≥0.2) in one or both eyes or a two-line interocular visual acuity difference and absence of any pathological ocular factors. The quality of life was assessed with a 15D questionnaire, and educational outcome, school success, and episodic memory with a CANTAB-PAL (paired associates learning) test were evaluated. RESULTS The prevalence of amblyopia in the current adult population aged 46 years was 1.3% (n = 36). At 14 years, the amblyopia subjects had had significant differences in mean spherical equivalent between the amblyopic and fellow eye and strabismus more often than controls. No significant differences were observed in the CANTAB-PAL test or in educational outcome. However, amblyopia subjects had significant difficulties in the 15D questionnaire in terms of vision (54% vs. 34%, p = 0.01). CONCLUSION Due to screening and treatment in childhood, the number of adults with residual amblyopia was low. Despite minor visual impairment and discomfort, they cope very well in life in terms of educational outcome and quality of life.

Abstract
PURPOSE Postoperative endophthalmitis is a devastating complication, leading to poor visual prognosis. The purpose of this study is to determine the incidence, risk factors, and visual outcome of post-cataract surgery endophthalmitis in Malaysia over a 9-year period (2012-2020). METHODS Data from National Eye Database (NED), involving all patients who have undergone cataract surgery from January 2012 until December 2020 were analyzed. RESULTS Total number of patients who had undergone cataract surgery between the year 2012 till 2020 were 231,281 patients (267,781 eyes). Incidence of POE in this population was 0.08%. Patient aged 70 and above (p-value 0.047), Malay ethnicity (p-value: 0.009), presence of ischemic heart disease, renal failure, diabetic retinopathy, and poorer preoperative vision were shown to have a higher risk of POE. Cataract surgeries done in KK-KKM, duration more than 45 minutes, use of general anaesthesia, and no IOL or ACIOL implantation were significantly more in POE patients. Multivariate analysis revealed Malay ethnicity, presence of ocular comorbidity, poor preoperative vision, ACIOL, and presence of intra-operative complication were predictive factors for POE. CONCLUSIONS Incidence of POE is low in the Malaysian population. Surgeons have to be aware that Malay ethnicity, presence of ocular comorbidity, poor preoperative visual acuity, placement of IOL and complicated cataract operation have higher risk of POE.

A comparative clinical study of postoperative care by teleophthalmology and in-person consultation at hospital outpatient department after an uncomplicated cataract surgery. Oman J Ophthalmol 2023; 16:446-451. [PMID: 38059100 PMCID: PMC10697269 DOI: 10.4103/ojo.ojo_82_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 04/06/2022] [Accepted: 06/22/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Teleophthalmology provides an opportunity to conduct consultations in far-flung and remote areas that have no access to specialized eye care. However, there is a paucity of studies to assess the effect of missing in-person follow-up on initial postoperative visits. The study thus aims to compare postoperative satisfaction and uncorrected distance visual activity after an uneventful phacoemulsification cataract surgery in patients with teleconsultation approach to those with hospital visit. MATERIALS AND METHODS The prospective observation study (n = 240) was conducted in patients who underwent surgery for cataract. Pre- and post-operative data were collected and divided into two groups based on the type of postoperative follow-up. All patients were scheduled for ophthalmic reviews in the hospital on day 1, day 7, and day 30-40 (hospital visit group) or through teleconsultation on days 1 and 7 followed by a hospital visit on days 30-40 (teleconsultation group). Outcomes evaluated in both groups were complications, patient satisfaction, and uncorrected distance visual acuity. RESULTS Most patients in both groups were in the age group of 51-70 years. Overall satisfaction was comparable in teleconsultation and hospital visit groups (3.74 ± 0.23 vs. 3.72 ± 0.27; P = 0.22). The majority of patients had visual acuity 6/18-6/6 on postoperative day 1, day 7, and day 30-40 in both groups. Lid edema, pain, redness, watering, and congestion complications were more in the hospital visit group on postoperative day 1. CONCLUSION The study concludes that patients with no preexisting ocular and systemic comorbidity undergoing an uneventful phacoemulsification cataract surgery teleconsultation approach can be used for follow-up without any impact on the postoperative visual outcome and patient satisfaction, thereby increasing the efficiency and productivity of health-care system.

Abstract
Cataract surgery helps to enhance visual function and improve the quality of life of cataract patients. The present study assessed visual outcomes and explored health-related quality of life (HRQoL) and factors associated with it following cataract surgery in Armenia. An interviewer-administered survey along with the ophthalmologic examination was conducted among 248 patients. It explored socio-demographic characteristics, use of eye care services, smoking status, comorbidities, and receiving and giving social support. A Short Form Health Survey (SF-36) was used to measure HRQoL. Simple and multivariable linear regression was used for the analysis. About 72.8% of examined eyes had good visual outcomes, while 17.7% had borderline outcomes. Poor visual outcomes were detected in 9.5% of the eyes. The mean composite SF-36 score for physical health was 50.8, while the mean composite score for mental health was 49.9. Gender, socioeconomic status, having a non-communicable disease, and receiving and giving tangible social support were significantly associated with SF-36 physical component in the adjusted analysis, while the variables which demonstrated significant association with the mental component included socioeconomic status, having a non-communicable disease, and giving tangible support. The visual outcome after cataract surgery in Armenian patients is below WHO-recommended standards. The quality of ophthalmological surgical care should be monitored to maximize the visual outcome in Armenian patients, with a focus on women, patients with poor socioeconomic status, and those with non-communicable diseases.

Clinical profile and visual outcome in patients with traumatic optic neuropathy. Indian J Ophthalmol 2023; 71:3046-3052. [PMID: 37530279 PMCID: PMC10538853 DOI: 10.4103/ijo.ijo_3318_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 08/03/2023] Open
Abstract
Purpose To analyze the visual outcome in patients with traumatic optic neuropathy (TON) with respect to different treatment modalities, to study the correlation of initial visual loss with the final visual outcome, and to find out the predictor of final visual outcome in patients with indirect TON. Methods A retrospective analysis of 36 eyes with TON was done. Data on clinical profile, including demographics, mode of trauma, best corrected visual acuity (BCVA), pupillary reflex examination, and anterior and posterior segment examination, was collected. Presence and location of orbital and cranial fractures were identified from computed tomography scan. Visual outcomes following steroid therapy, optic nerve (ON) decompression, and in untreated patients were analyzed. Pre- and post-treatment BCVA were divided into three groups based on logarithm of the minimum angle of resolution (logMAR) as follows: group A: 3, group B: 2.9-1.3, and group C<1.3. BCVA values at follow-up visits were taken as the primary outcome measure. Association between various risk factors and final visual outcome in patients with indirect TON was also analyzed. Results Out of 34 patients whose 36 eyes were studied, three (8.8%) patients were females and 31 (91.2%) patients were males. Most common mode of trauma was road traffic accident (RTA; 91.2%), which was followed by fall (8.8%) and assault (2.9%). Pre- and post-treatment BCVA values of 36 eyes were compared, and improvement in BCVA after treatment was found to be statistically significant. Also, 28.6% of patients with presenting BCVA of no light perception showed improvement compared to 94.1% and 100% in groups B and C, respectively. Orbital wall fractures were seen in 80.5% (n = 29) of the patients, with lateral wall fracture being the most common (58.3%) followed by medial wall (33.3%), roof (27.7%), floor (27.7%), and optic strut (5%). Conclusion Baseline BCVA had significant association with final vision improvement. Lateral wall fracture was the most common fracture associated with indirect TON. Patients treated with high-dose corticosteroids, irrespective of the time of presentation, had a better visual outcome.

Role of Antimicrobial Resistance in Outcomes of Acute Endophthalmitis. Antibiotics (Basel) 2023; 12:1246. [PMID: 37627666 PMCID: PMC10451699 DOI: 10.3390/antibiotics12081246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 07/27/2023] [Accepted: 07/27/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND This study explores local trends in antimicrobial resistance and its influence on long-term visual outcomes following treatment with broad-spectrum empiric intravitreal antibiotics. METHODS All patients undergoing intraocular sampling for endophthalmitis from Auckland between January 2006-May 2023 were included. The impact of antimicrobial resistance on the final visual outcome was analysed using logistic regression models. RESULTS 389 cases of endophthalmitis were included, and 207 eyes (53.2%) were culture positive. When tested, all Gram-positive microorganisms were fully susceptible to Vancomycin, and all Gram-negative microorganisms demonstrated full or intermediate susceptibility to Ceftazidime. Resistance to at least one antimicrobial agent was present in 89 culture results (43.0%), and multidrug resistance (resistant to ≥3 antimicrobials) in 23 results (11.1%). No increase in resistance was observed over time. The primary procedure was a tap and inject in 251 eyes (64.5%), and early vitrectomy was performed in 196 eyes (50.3%). Severe vision loss (≤20/200) occurred in 167 eyes (42.9%). Antimicrobial resistance was associated with an increased risk of retinal detachment (OR 2.455 p = 0.048) but not vision loss (p = 0.288). CONCLUSION High sensitivity to Vancomycin and Ceftazidime was present in our population, reinforcing their role as first-line empiric treatments. Resistant microorganisms were associated with an increased risk of retinal detachment but no alteration in final visual outcome.

Abstract
Objective: Advanced proliferative diabetic retinopathy can lead to serious ophthalmological complications, including blindness. This research aimed to determine visual outcomes after pars plana vitrectomy secondary to proliferative diabetic retinopathy, as well as to identify its predictors. Methods: This prospective clinical study was performed in the Ophthalmology Clinic of the Clinical Centre University of Sarajevo. 60 subjects (eyes) with performed pars plana vitrectomy secondary to proliferative diabetic retinopathy were included in the study. Results: After univariate linear regression analysis, glucose, HbA1c, vascular endothelial growth factor, previous pan-retinal laser photocoagulation, baseline best corrected visual acuity, gas injection, vitreous haemorrhage, iris rubeosis, and glaucoma were found to be statistically significant parameters associated with postoperative visual outcome (p<0.05). Multivariate linear regression analysis was performed to evaluate the association between factors and postoperative best corrected visual acuity. Only intravitreal vascular endothelial growth factor concentration, previous pan-retinal photocoagulation, and gas injection remained statistically significant associated with postoperative best corrected visual acuity (p<0.05). Conclusion: Vitrectomy is an effective treatment for advanced proliferative diabetic retinopathy. Factors correlated with the better visual outcome are good systemic control, previous pan-retinal photocoagulation, low intravitreal vascular endothelial growth factor concentration, younger age, intraoperative internal gas tamponade, combined phacoemulsification and pars plana vitrectomy surgery, and the absence of postoperative complications. Abbreviations: PDR = proliferative diabetic retinopathy, VEGF = vascular endothelial growth factor, TDR = tractional retinal detachment, BCVA = best corrected visual acuity, DR = diabetic retinopathy, RDD = rhegmatogenous retinal detachment, NVG = neovascular glaucoma, BRVO = branch retinal vein occlusion, CBC = complete blood count, DBT = differential blood count, ESR = erythrocyte sedimentation rate, HbA1c = glycosylated hemoglobin, PHACO = phacoemulsification, ILM = internal limiting membrane, PPV = pars plana vitrectomy, IOP = intraocular pressure, PRP = pan-retinal photocoagulation, ETDRS = Early treatment diabetic retinopathy study.

Abstract
IMPORTANCE Diabetic macular edema (DME) is a major cause of vision loss in patients with diabetes mellitus. Intravitreal dexamethasone is a treatment option for patients unsuitable for or non-responsive to anti-angiogenic agents. OBJECTIVE To quantify visual and anatomical outcomes from an initial intravitreal dexamethasone injection over the expected 6-month period of dexamethasone release by the implant. Design and enrolment: This is a retrospective cohort study using electronic medical records of patients reviewed between 1 January 2012 and 1 April 2022. SETTING A tertiary eye-care center in London, United Kingdom; Moorfields Eye Hospital National Healthcare System Foundation Trust. PARTICIPANTS The cohort comprised 418 adult patients with DME who received an initial treatment of 700 µg intravitreal dexamethasone in the study period. Of these, 240 patients met the inclusion criteria of ≥2 hospital visits following initial injection (≥1 beyond 6 months) and no previous ocular corticosteroid treatment or missing assessment at baseline. EXPOSURE(S) Intravitreal dexamethasone implant (700 µg). MAIN OUTCOME(S) AND MEASURE(S) Probability of a positive visual outcome, defined as ≥5 or ≥10 Early Treatment Diabetic Retinopathy Study (ETDRS)-letter gain after treatment when compared to baseline (Kaplan-Meier models). RESULTS From the initial intravitreal dexamethasone injection alone, we observed a >75% chance of gaining ≥5 ETDRS letters and >50% chance of gaining ≥10 ETDRS letters within 6 months. There was less than a 50% chance of sustaining either positive visual outcome beyond 4 months. CONCLUSIONS AND RELEVANCE Most patients can be expected to have a positive visual outcome following an initial injection of dexamethasone implants that subsides within 4 months. Real-world re-treatment was observed to be delayed until after visual benefits were lost in half of the cohort. Further research will be needed to study the effects of delays in re-treatment.

Abstract
Background The visual outcome and the effect of cataract surgery on existent and surgically induced refractive errors are a concern of interest that the eye care expert must deal with. Objectives The aim of the study was to investigate the visual outcome after small incision cataract surgery of patients in a Kenyan hospital. Methods A descriptive retrospective study covering 3 years (2015 to 2017). Total of 1104 files of patients aged > 50 years who had undergone small incision cataract surgery at Sabatia eye hospital were purposively selected. Information on demographics, clinical aspects and outcome was collected using a ministry of health structured form. Statistical package for social sciences version 24 was used to analyse the data. Results Of the 1104 patients, 55% (n=606) were females. The mean age of patients was 70.6 ± 9.8 years. Most patients were from the hospital neighbourhood. Visual acuity improved by 38.9%, 28.9%, 19.8% and 11.5% in patients aged 50-59, 60-69, 70-79, and 80-89 years old, respectively. Conclusion Small incision cataract surgery improved visual acuity in all patients' groups, but the outcome is influenced by age, refractive error particularly astigmatism.

Abstract
Transepithelial photorefractive keratectomy (Trans PRK) is a relatively new technology for refractive surgery and has shown promising results in myopia correction. The data on hyperopia correction by this method are limited. In this review, we have attempted to understand the outcomes of this technology on hyperopic eyes. There are comparable results with conventional PRK and laser in situ keratomileusis (LASIK) as far as refractive stability, regression rate, predictability, and post-operative complications are concerned. The best results have been obtained in lower hyperopic corrections. In moderate to higher hyperopia, the limited data available show higher regression, unstable visual outcomes, and increased stromal haze. There is a need to evaluate the technology further to understand its success for hyperopic refractive surgery.

Comparative analysis of outcomes following craniotomy and expanded endoscopic endonasal approach resection of tuberculum sellae meningiomas: a single-institution study. Front Neurol 2023; 14:1139968. [PMID: 37260603 PMCID: PMC10228730 DOI: 10.3389/fneur.2023.1139968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 04/20/2023] [Indexed: 06/02/2023] Open
Abstract
Background Traditionally, supratentorial craniotomy has been used to sever tuberculum sellae meningiomas (TSMs), but there has been a remarkably increasing tendency of extended endoscopic endonasal approach (EEEA) used to treat TSMs in the recent decade. Several documents have described the advantages and disadvantages of both approaches, but there is no consensus on whether one is superior to the other. Objective This study aimed to compare surgical outcomes between craniotomy and EEEA for TSMS treated at our institution. Methods From January 2015 to December 2021, a total of 84 cases of TSMs were included in this study. Cases were separated into two groups: the craniotomy group and the EEEA group. Their anamneses and surgical records were reviewed. Demographic data, presenting symptoms, tumor volume, extent of resection, visual outcomes, and follow-up data were tabulated. The Kaplan-Meier curves were constructed for the PFS for both cohorts. Results Complete data were available for 84 surgeries; 39 cases were treated via craniotomy, and 45 were treated via EEEA. Patient demographic data, pre-operative symptoms, and tumor characteristics were similar between the two cohorts. The extent of resection was similar between the two groups (GTR: 91.11% EEEA vs. 87.18% craniotomy; STR 8.89 vs. 12.82%, p = 0.91). There was no difference in visual outcomes between both groups (92.1 vs. 84.84%, p = 0.46). An increased rate of cranial nerve injury was noted in the craniotomy group (0 vs. 10.25%, p = 0.04). Post-operative CSF leak rate occurred in one patient in the EEEA group. The PFS curves (p = 0.52) and recurrence/progression rates (13.33 vs. 20.51%, p = 0.39) were similar between the two groups. Conclusion Both EEEA and craniotomy can successfully sever TSMs. The recurrence/progression rate and PFS appear to be similar between the two groups. Although there are no differences in EOR and visual outcomes between the two groups, there was a clear trend in the EEEA group to obtain a better outcome. CSF leakage was common in the EEEA cohort, whereas the rate of cranial nerve injury was found to be higher in the craniotomy cohort. We believe that our data support the conclusion that EEEA surgery is the preferred approach for the removal of TSMs.

Abstract
PURPOSE To determine the characteristics, primary sources, pathogens, risk factors, and visual outcomes in patients with endogenous endophthalmitis (EE). METHODS We performed a retrospective cohort study of 61 consecutive patients with EE (74 affected eyes) and reported on prevalence, clinical courses, prognostic factors and visual outcomes. RESULTS Prevalence of EE was 5% of all patients with endophthalmitis. Among culture-positive cases (89%), Gram-positive species dominating (69%) followed by Gram-negative with 22% and fungal species with 9%. Regarding to visual outcomes, the mean visual acuity (VA, ETDRS letters) at baseline, 3-months, 6-months and 1-year follow-up was 0.85, 9, 8 and 9, respectively. Initial VA of hand movement or better (P 0.007) and bilateral infection (P 0.004) were associated with better visual outcome. CONCLUSION The prognosis for EE remained poor despite aggressive and immediate treatment. The high suspicion, early diagnosis and prompt treatment are important factors that might lead to the better outcome.

Abstract
Purpose The aim of this study was to determine the predisposing risk factors, clinical characteristics, microbiological profile, and visual and functional treatment outcome of microbial keratitis including viral keratitis in children. Methods A prospective study was carried out in a tertiary care institute over a period of 18 months on 73 pediatric patients. Data collected was analyzed for demographics of the patient population, causative organisms, and management outcome in terms of visual and functional outcome. Results Patients in the age group from 1 month to 16 years were included, with a mean age of 10.81 years. Trauma was the commonest risk factor (40.9%), with unidentified foreign body fall being the most common (32.3%). No predisposing factors were identified in 50% of cases. Also, 36.8% of eyes were culture positive, with bacterial isolates in 17.9% and fungus in 82.1%. Moreover, 7.1% eyes were culture positive for Streptococcus pneumoniae and Pseudomonas aeruginosa each. Fusarium species (67.8%) was the commonest fungal pathogen, followed by Aspergillus species (10.7%). Also, 11.8% were clinically diagnosed as viral keratitis. No growth was found in 63.2% of patients. Treatment with broad-spectrum antibiotics/antifungals was administered in all cases. At the final follow-up, 87.8% achieved a best corrected visual acuity (BCVA) of 6/12 or better. Therapeutic penetrating keratoplasty (TPK) was required by 2.6% of eyes. Conclusion Trauma was the major cause for pediatric keratitis. Majority of the eyes responded well to medical treatment, with only two eyes needing TPK. Early diagnosis and prompt management helped majority of the eyes to achieve a good visual acuity after the resolution of keratitis.

Abstract
PURPOSE To report long-term treatment outcomes of intravitreal bevacizumab in myopic macular neovascularization (MNV). METHODS Retrospective analysis of longitudinal, clinical data of patients with high myopic MNV treated with intravitreal bevacizumab. One-hundred and seventeen eyes of 106 patients were followed from first injection up to 12 years. Outcome measures were best-corrected visual acuity change during follow-up and myopic MNV recurrence. RESULTS Mean (±SD) baseline best-corrected visual acuity (0.56 ± 0.46 logMAR, 20/80) significantly improved after first treatment (0.33 ± 0.33, 20/50, P < 0.001). At 4 years (n = 86), best-corrected visual acuity was no longer significantly better than at baseline (0.55 ± 0.57, P = 0.30) and continued to deteriorate to 0.84 ± 0.76 (20/125) at 10 years (n = 27). Of the 27 eyes (23%) who reached 10 years of follow-up, 53% developed MNV-related chorioretinal atrophy. The cumulative incidence of recurrent myopic MNV was 34% at 2 years and 59% at 5 years. Best-corrected visual acuity decrease in eyes with or without recurrent MNV was similar ( P = 0.58). Patchy chorioretinal atrophy (hazard ratio 3.0, P = 0.02) and subfoveal MNVs (hazard ratio 2.5, P = 0.048) were significantly associated with recurrent MNV. CONCLUSION This retrospective myopic MNV study revealed that visual improvement after intravitreal bevacizumab injections was not maintained over time. Macular neovascularization recurrences occurred frequently but did not alter the already poor visual prognosis.

Abstract
OBJECTIVE Tuberculum sellae meningiomas (TSMs) present a burdensome surgical challenge because of their adjacency to vital neurovascular structures. The contralateral subfrontal approach provides an outstanding corridor for removing a TSM with an excellent visual outcome and limited complications. The authors present their long-term surgical experience in treating TSMs via the contralateral subfrontal approach and discuss patient selection, surgical techniques, and clinical outcomes. METHODS Between 2005 and 2021, the authors used the contralateral subfrontal approach in 74 consecutive patients presenting with TSMs. The surgical decision-making process and surgical techniques are described, and the clinical outcomes were retrospectively analyzed. RESULTS The mean patient age was 54.4 years, with a female predominance (n = 61, 82%). Preoperatively, 61 patients (82%) had vision symptoms and 73 (99%) had optic canal invasion by tumor. Gross-total resection was achieved in almost all patients (n = 70, 95%). The visual function improvement and stabilization rate was 91% (67/74). Eight patients (11%) showed a worsening of visual function on the less-compromised (approach-side) optic nerve. There was no occurrence of cerebrospinal fluid leakage. Four patients (5%) experienced recurrences after the initial operation (mean follow-up duration 63 months). There were no deaths in this study. CONCLUSIONS The contralateral subfrontal approach provides a high chance of complete tumor removal and visual improvement with limited complications and recurrences, especially when the tumor is in a unilateral or midline location causing unilateral visual symptoms or bilateral asymmetrical visual symptoms, regardless of tumor size or encasement of major vessels. With the appropriate patient selection, surgical technique, and familiarity with surrounding neurovascular structures, this approach is reliable for TSM surgery.

Abstract
Purpose To determine the predictors for visual outcome after silicone oil removal (SOR) in eyes with complicated retinal detachment. Patients and Methods A total of 182 eyes with complicated retinal detachment that had undergone SOR were retrospectively reviewed. Snellen best-corrected visual acuity (BCVA), intraocular pressure (IOP) and complications were recorded at baseline, 1 day, 1 month and 3 months postoperatively. Good visual outcome was defined as best-corrected visual acuity of ≥20/200 at 3 months visit. Factors predicting visual outcome were evaluated using univariate and multivariate analysis. Results After SOR, anatomical retinal reattachment was noted in 165 eyes (90.66%). Good visual outcome (VA ≥ 20/200) was achieved in 104 eyes (57.14%) at 3 months after SOR. For the eyes that remained attached after SOR, the percentage of good visual outcome was 63.03%. With univariate and multivariate analysis, visual acuity before SOR (p<0.001), circumferential peripheral retinopexy (p=0.037), additional endolaser during SOR (p=0.004), and pseudophakia status at the last follow up (p=0.021) were associated with visual outcome. Complications after SOR included redetachment (9.4%), hypotony (6.6%) and bullous keratopathy (1.7%). Conclusion While anatomically attached retina was achieved in most of the patients, the functional outcomes were still much lower. Good BCVA before SOR and pseudophakia status at the last follow up were predictors for good visual outcomes, whereas circumferential peripheral retinopexy and additional endolaser during SOR were predictors for poor visual outcomes after SOR in eyes with complicated retinal detachment.

Abstract
BACKGROUNDS Bevacizumab (BVZ) is used as a subsequent line of treatment for pediatric optic pathway glioma (OPG) in the case of progression. Data on the treatment effect concerning tumor progression and visual function are scarce and nationwide studies are lacking. METHODS We performed a retrospective, nationwide, multicentre cohort study including all pediatric patients with OPG treated with BVZ in the Netherlands (2009-2021). Progression-free survival, change in visual acuity and visual field, MRI-based radiologic response, and toxicity were evaluated. RESULTS In total, 33 pediatric patients with OPG were treated with BVZ (median 12 months). Visual acuity improved in 20.5%, remained stable in 74.4%, and decreased in 5.1% of 39 of all analysed eyes. The monocular visual field improved in 73.1%, remained stable in 15.4%, and decreased in 7.7% of 25 analysed eyes. Radiologic response at the end of therapy showed a partial response in 7 patients (21.9%), minor response in 7 (21.9%), stable disease in 15 (46.9%), and progressive disease in 3 (9.3%). Progression-free survival at 18 and 36 months after the start of BVZ reduced from 70.9% to 38.0%. Toxicity (≥grade 3 CTCAE) during treatment was observed in five patients (15.2%). CONCLUSION Treatment of BVZ in pediatric patients with OPG revealed stabilisation in the majority of patients, but was followed by progression at a later time point in more than 60% of patients. This profile seems relatively acceptable given the benefits of visual field improvement in more than 70% of analysed eyes and visual acuity improvement in more than 20% of eyes at the cessation of BVZ.

[PMID: 36514522 PMCID: PMC9723839 DOI: 10.29399/npa.27997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Accepted: 11/21/2021] [Indexed: 12/15/2022] Open
Abstract
Introduction Previous reports described a pattern of hypoglycemia-induced damage predominantly affecting the parieto-occipital regions. The long-term neurological sequelae of severe neonatal hypoglycemic encephalopathy include developmental delay, poor head growth, learning or behavioral difficulties, visual impairment, and epilepsy. This study reports neurodevelopmental outcome of children with neonatal hypoglycemia-associated parieto-occipital brain injury who were evaluated in our pediatric neurology outpatient clinic for different neurological complaints. Methods We retrospectively reviewed patients who were followed at Kocaeli University Hospital, Pediatric Neurology Department between 2007 and 2015. Patients (n=42) with predominately parieto-occipital lesions on magnetic resonance imaging (MRI) with the typical pattern of neonatal hypoglycemia were evaluated. Patients with documented hypoglycemia (n=21) were included in this study. Patients (n=9) with recurrent episodes of hypoglycemia longer than 12 hours were evaluated as prolonged hypoglycemia. Results Eleven patients (52.4%) experienced seizures in the neonatal period. Eighteen patients (85.7%) developed epilepsy during the follow-up. Refractory seizures were observed in 8 patients (38.1%). Nine patients (42.9%) manifested microcephaly, seven patients (33.3%) manifested cerebral palsy. Parieto-occipital involvement and the spasticity rate were statistically high in patients with prolonged hypoglycemia (p<0.01). Two patients had autistic features and four patients (19%) had attention deficit hyperactivity disorder. VEP studies could be performed in 18 of 21 patients. All patients had abnormal VEP results. Conclusion We are of the opinion that most patients of neonatal hypoglycemia are not always documented. Patients under risk and patients with symptoms of hypoglycemia should be vigorously screened and treated to prevent neurologic impairments including cerebral palsy, epilepsy and visual disturbance.

Abstract
Purpose To analyze intraoperative difficulties and visual and surgical outcomes following pediatric cataract surgery. Methods This five-year retrospective study (2014-2019) included 138 eyes (85 children) with cataract aged between 12 months and 18 years (either sex). All children had undergone best-corrected visual acuity (BCVA), anterior and posterior segment evaluation, intraocular lens (IOL) power calculation, superior manual-small-incision cataract surgery (MSICS) with or without posterior capsulotomy/anterior vitrectomy and IOL implantation under general or local anesthesia, visual rehabilitation, and had been followed up for a minimum period of 12 months. Results The mean age was 111.27 ± 4.84 months. Preoperative BCVA distance: 113 (81.88%)eyes had BCVA < 6/60; near BCVA: 114 (82.6%) eyes had ≤N36. At last postoperative follow-up (mean: 20.98 ± 13.08 months): distant BCVA- ≥6/60 had been recorded in 120 (86.96%) eyes; near BCVA- >N36 in 123 (89.13%) eyes. Improvement in BCVA was statistically significant. Intraoperative scleral tunnel difficulties were seen in three eyes (thin flap in two, and buttonhole in one eye); in the majority of the eyes 113 (81.88%), IOL was placed in the bag. Twenty eyes had early postoperative inflammation. At last follow-up: posterior capsular opacity was recorded in six eyes, IOL decenteration in two eyes, secondary glaucoma in six eyes, and severe amblyopia in 36 (26.09%) eyes. The mean myopic shift was - 1.11 ± 0.89 D and was statistically significant. Conclusion Superior MSICS as a treatment for pediatric cataract has minimal intraoperative complications and satisfactory visual and surgical outcomes.

Analysis of Systemic Risk Factors and Post-Insult Visual Development in a Danish Cohort of Patients with Nonarteritic Anterior Ischemic Optic Neuropathy. Clin Ophthalmol 2022; 16:3415-3424. [PMID: 36249446 PMCID: PMC9560866 DOI: 10.2147/opth.s384740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 09/09/2022] [Indexed: 11/07/2022] Open
Abstract
Purpose Nonarteritic anterior ischemic optic neuropathy (NAION) is associated with vascular as well as anatomical risk factors. Following the insult, the visual development varies from minor to severe deterioration. The aim of this study was to examine possible prognostic systemic risk factors and their eventual impact on post-insult visual development in NAION patients. Methods A retrospective chart review of all NAION patients (18–79 years at time of diagnosis) seen a minimum of two times in a tertiary eye department during a 10-year period in regard to systemic diseases, medication, lifestyle factors and ophthalmic examination was performed. Visual outcome was assessed according to the development of best corrected visual acuity (BCVA) and visual field from initial to final visit. Results There were 163 eligible patients. A greater proportion of the patients in the total cohort were over 50 years of age (79.8%) and men (66.3%). In total, 59.5% of the patients had a stable BCVA, while 25.8% experienced improvement, and 14.7% had deterioration. Seventy-two percent of the patients had a stable visual field, while 14% had improvement, and 14% had deterioration. No association between visual outcome and clinical characteristics, medication or systemic risk factors were identified. Conclusion We did not find any association between patient characteristics and systemic risk factors at time of diagnosis and visual development post-insult. This could suggest that the optic nerve head anatomy plays a larger role for visual outcome than previously estimated.

Impact of Treating Age-Related Macular Degeneration before Visual Function Is Impaired. J Clin Med 2022; 11:jcm11195726. [PMID: 36233594 PMCID: PMC9573686 DOI: 10.3390/jcm11195726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 09/11/2022] [Accepted: 09/23/2022] [Indexed: 11/23/2022] Open
Abstract
Visual outcomes of age-related macular degeneration (AMD) have substantially improved via anti-vascular endothelial growth factor (anti-VEGF) therapy. However, the treatment effects vary among individuals. Medical charts of 104 eyes (104 patients) with AMD, treated with anti-VEGF drugs and followed up for 12−36 months, were retrospectively analyzed. Logistic regression analyses adjusted for age showed that eyes with an initial best-corrected visual acuity (BCVA) < 0.3 in the logarithm of the minimum angle of resolution (logMAR) were a positive predictor (odds ratio = 3.172; 95% confidence interval [CI] = 1.029−9.783; p = 0.045), and the presence of initial fibrovascular pigment epithelial detachment (PED) was a negative predictor (0.222; 0.078−0.637; p = 0.005) of maintained or improved BCVA at the final visit. Kaplan−Meier survival analysis showed that eyes with an initial BCVA < 0.3 (Cox hazard ratio = 2.947; 95% CI = 1.047−8.289; p = 0.041) had a better survival rate after adjusting for age when failure was defined as a BCVA reduction ≥ 0.2 of logMAR. Eyes with an initial BCVA < 0.3 belonged to younger patients; more frequently had subretinal fluid as an exudative change; and less frequently had intraretinal fluid, submacular hemorrhage, and fibrovascular PED. Initiating anti-VEGF treatment before BCVA declines and advanced lesions develop would afford better visual outcomes for AMD eyes in the real-world clinic, although further analyses are required.

Safety and Efficacy of Cataract Surgery Under a Local Infection Control Protocol Before and During a COVID-19 Wave in Thailand for Healthcare Workers and Patients: A Prospective Cohort from a Secondary Center. Clin Ophthalmol 2022; 16:1773-1781. [PMID: 35685377 PMCID: PMC9173727 DOI: 10.2147/opth.s366353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 05/25/2022] [Indexed: 11/26/2022] Open
Abstract
Purpose To assess the effectiveness of a local infection control protocol for cataract surgery (CS) during the coronavirus disease (COVID-19) pandemic and determine the trend of CSs and visual outcomes during this period, as compared to the pre-COVID-19 pandemic period. Methods This study was conducted at Suddhavej Hospital, Mahasarakham University, Mahasarakham, Thailand, between July 1, 2020, and March 31, 2021. In this two-phase study, we used only a COVID-19-screening questionnaire during the first phase and preoperative nasopharyngeal swab severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing for real-time reverse transcriptase-polymerase chain reaction in the second phase, during Thailand's second COVID-19 wave. Nasopharyngeal swab SARS-CoV-2 nucleic acid testing, SARS-CoV-2 IgG/IgM, or anti-SARS-CoV-2 spike antibody seroconversion was used to detect COVID-19 infection among healthcare workers. We also compared cataract surgical volume and postoperative visual acuity of CS patients between the pre-COVID-19 period and during the COVID-19 pandemic period. Results A total of 947 patients underwent CS. Thirty-two healthcare workers and 275 patients tested negative for SARS-CoV-2 in the second study phase. CSs increased on average by 50.09% month-to-month when the surgery was resumed. The mean postoperative logMAR best-corrected visual acuity was significantly better in the COVID-19 pandemic period than in the pre-pandemic period (difference, 0.1 [95% CI: 0.00-0.12], p < 0.0001). Conclusion CS could be safely performed under an infection control protocol during the COVID-19 pandemic. The cataract surgical volume, with favorable visual outcomes, has an increasing trend after resuming elective surgeries.

Abstract
Objectives To evaluate the associations between anatomical changes and visual outcomes in patients with idiopathic epiretinal membrane (ERM). Materials and Methods We performed a prospective study of 130 consecutive idiopathic ERM patients and report their visual outcomes and the factors associated with visual outcome and anatomical changes. Results Of 130 eyes of 130 patients, 87 eyes underwent surgery, while the remaining 43 eyes were observed. At 6-month follow-up, the best-corrected visual acuity (BCVA) increased in the whole population. Mean Early Treatment Diabetic Retinopathy Study letter score changed from 51 to 65 in the surgical group and from 67 to 68 in the non-surgical group. The surgical group had improvement in BCVA at all ERM stages and grades of disorganization of the retinal inner layers (DRIL) (p<0.01). In multivariable analysis of the surgical group, factors associated with BCVA of ETDRS 60 letters or more were no or mild DRIL and the absence of ellipsoid zone disruption at baseline (p=0.002 and p=0.034, respectively) and this statistically significant positive correlation was still maintained at 12-month follow-up. Conclusion Baseline DRIL grade and presence of ellipsoid zone disruption were the most informative prognostic factors in patients with idiopathic ERMs. Patients with severe DRIL and/or advanced ERMs had improved vision after ERM removal.

Abstract
OBJECTIVE To describe the clinical features, management, and outcome of dogs presenting with sports ball projectile ocular injuries. ANIMALS STUDIED Eighteen dogs. PROCEDURES A retrospective study reviewing cases of ocular injury due to a sports ball projectile that presented to the Cornell University ophthalmology service between 2004 and 2021. Dog age, type of sports ball, initial ocular lesions, eye affected, clinical management, and visual outcome were recorded. RESULTS Sports ball projectile ocular injuries were identified in 18 eyes of 18 dogs. The median age of the dogs was 1.0 years old, ranging from 0.3- to 9-years- old. Nine dogs were male, and 9 were female. Ocular injuries were caused by small, dense balls (e.g., golf balls, baseballs) in 11 dogs; small, light balls (e.g., tennis balls, toy balls) in 5 dogs; and large, soft balls (e.g., soccer ball, football) in 2 dogs. Closed-globe injuries (12 of 18 eyes) presented with traumatic uveitis (91%), hyphema (45%), and subconjunctival hemorrhage (18%). All 12 closed-globe injury cases were medically managed, eight dogs remained visual. Open-globe injuries (6 of 18 dogs) presented with three corneal lacerations and three scleral ruptures. Five open-globe injuries required enucleation, and one was medically managed and maintained vision. CONCLUSION Sports ball projectile ocular injuries in dogs can result in substantial ocular morbidity and in loss of vision. Small, dense balls were associated with injuries that carried the most guarded prognosis and required more aggressive management. Small and large lighter projectiles were associated with less serious ocular injuries and visual outcomes.

Abstract
PURPOSE To investigate long-term visual outcomes of patients with polypoidal choroidal vasculopathy (PCV) and typical neovascular age-related macular degeneration (nAMD) in the real-world setting. METHODS Retrospective, multicenter, noninterventional consecutive cohort study. Two hundred eighty-five eyes of 261 patients with PCV and 902 eyes of 877 patients with typical nAMD, who could be followed up 1 year or longer from 2005 to 2018, were included. Mean changes in best-corrected visual acuity (BCVA) from baseline in the PCV and the typical nAMD groups were compared. RESULTS Mean follow-up period of total patients was 4.3 ± 2.8 (1-10) years. Baseline BCVA was better in the PCV group than that in the typical nAMD group (0.59 ± 0.52 versus 0.79 ± 0.63 logMAR, p < 0.001). The mean changes in BCVA from baseline in the PCV and nAMD group were +2.1 and -0.1 letters at 1 year, -0.2 and -3.7 letters at 3 years, -3.9 and -10.5 letters at 5 years and - 8.7 and - 12.1 letters at 7 years, respectively. Before 2006, the initial BCVA was sustained for approximately 1 year in eyes with PCV and for less than half year in eyes with typical nAMD. However, after 2007, when anti-VEGF agents were available, the initial BCVA was sustained for 4 years in eyes with PCV, while it was sustained for 1 year in eyes with typical nAMD. CONCLUSION In the real-world, long-term BCVA deteriorated in both PCV and typical nAMD groups, but the PCV group showed better visual outcomes than the typical nAMD group.

Abstract
PURPOSE To evaluate the effects of prophylactic vitrectomy for rhegmatogenous retinal detachment (RRD) risk and visual outcome in acute retinal necrosis (ARN). METHODS A systematic search of online databases was performed for articles published between 1994 June and 2020 March. The main outcomes that were assessed by a fixed effects model were RRD risk and visual outcome during a follow up period. RESULTS A total of 7 trials involving 265 eyes (121 prophylactic vitrectomy eyes vs 144 routine antiviral treatment eyes) were analyzed in this study. RRD risk significantly decreased in the prophylactic vitrectomy group compared to the routine antiviral treatment group (P < .001, OR = 0.27, 95% CI: 0.16-0.46, I2 = 35.3%). Significantly deteriorated visual outcome was observed in the prophylactic vitrectomy group in comparison with the routine antiviral treatment group (P < .001, WMD = 0.47, 95%CI: 0.26-0.67, I2 = 32.2%). CONCLUSION This meta-analysis of retrospective cohort studies revealed that prophylactic vitrectomy could reduce the risk of RRD. The silicone oil tamponade and long-term complications may result in deteriorated visual outcome.

Abstract
The aim of our investigation was to examine the possible correlations between optical aberrations, angle kappa, angle alpha, and visual outcomes following cataract surgery. In total, 56 eyes of 28 patients were implanted with the Liberty 677MY trifocal intraocular lens (IOL). Pre- and postoperative higher-order aberrations, coma, astigmatism, angle alpha, and angle kappa were registered, along with uncorrected and corrected visual acuities at multiple distances. Visual acuity and contrast sensitivity defocus curves were plotted, and the areas under the curve were calculated 1 and 3 months postoperatively. Excellent visual outcomes were found at all distances. Patients reported low levels of dysphotopsia, and 96.4% of patients achieved complete spectacle independence. While angle kappa significantly decreased during cataract surgery (p = 0.0007), angle alpha remained unchanged (p = 0.5158). Angle alpha correlated with postoperative HOAs and had a negative impact on near vision (p = 0.0543). Preoperative corneal HOA and coma had a strong adverse effect on future intermediate and near vision. Residual astigmatism significantly affected postoperative intermediate vision (p = 0.0091). Our results suggest that angle kappa is not an optimal predictive factor for future visual outcomes, while angle alpha and the preoperative screening of optical aberrations might help patient selection prior to multifocal IOL implantation.

Abstract
Purpose Owing to the paucity of literature on Indian children with periventricular leukomalacia (PVL), this retrospective study aimed to describe the visual and associated developmental abnormalities in a series of affected children attending a tertiary level eye care facility. Methods Children with radiologically confirmed PVL who attended the Pediatric Department of a tertiary eye hospital were included and underwent a detailed ocular and general developmental assessment. Results Of the 75 children, the mean age was 2.3 years, the mean follow-up was 3.1 years, 68% were males and 43% were born preterm. Grade I PVL was identified in 13 children (17%), Grade 2 PVL in 39 (52%), and Grade 3 PVL in 23 (31%). Premies with ≤2 kg (72.5%) and term babies with >2 kg (75%) had a greater association of PVL occurrence with a preponderance to severe PVL; 46% of the children were visually impaired which was significantly higher in the children with Grade 3 PVL (74%) than those with Grade 2 PVL (15%). Strabismus was common (80%) with a change in deviation over time. Seventy-one percent of the children had a refractive error, frequently myopic astigmatism. All the children except two had a delay in one or more general developmental milestones. Conclusion PVL occurrence is observed both in the babies born at term and premies, resulting in significant ocular and systemic morbidities. We recommend a system in place for early identification and referral to initiate an early intervention program which goes a long way toward improving the quality of life in these children.

Abstract
Aim The aim of the study was to evaluate the 1-year outcome of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy in an eye unit in sub-Saharan Africa. Methodology This retrospective study included 182 eyes of 172 patients managed in the vitreoretinal unit between 2016 and 2019 who were treated with intravitreal anti-VEGF bevacizumab (1.25 mg/0.05 ml) with at least 1 year of follow-up. The outcome measures were change in best-corrected visual acuity (BCVA) over 1 year of follow-up, the number of injections taken, and complications. Results The mean age was 61.1 ± 16.3 years (male-to-female ratio of 1:1.1) and about 62.1% above >60 years. A total of 330 injections were given during the period audited. The mean number of injections was 1.8 ± 0.93. Ninety-four (51.7%) eyes had only one injection, while 33 (18.1%), 50 (27.5%), and 5 (2.7%) had 2, 3, and 4 injections, respectively. About 78.5% had moderate-to-severe visual impairment at baseline and 44.5%, 16.4%, 12.6%, and 7.1% at 1, 3, 6, and 12 months post injections, respectively. The mean BCVA improved for all eyes from 1.67 ± 0.91 logarithm of minimum angle of resolution (logMAR) at baseline to 1.50 ± 1.27 logMAR at 1 year. The logMAR letters gained was 23 at 1 month and 8.25 at 1 year; the eyes that had three injections gained 10 letters, while those that had one injection gained three letters. Eyes with age-related macular degeneration and idiopathic polypoidal choroidopathy gained 7.5 and 9 letters, respectively, at 1 year after at least three injections. There was a statistically significant association between an increasing number of injections and improved visual outcome (P = 0.043). One patient each developed endophthalmitis (0.6%) and inferior retinal detachment (0.6%) post injection. Conclusion Visual acuity gain was recorded in patients who had intravitreal anti-VEGF injections in 1 year. It is recommended that patients should have more than one injection.

Abstract
Purpose: To assess the outcome of under-correction of intraocular lens (IOL) power in pediatric cataract surgery. Methods: We collected clinical data of 103 patients (181 eyes), all aged ≤15 years, who had undergone cataract surgery by a surgeon during 2006–2016. The mean duration of follow-up was 73 ± 38 months (range: 24–108). IOL power was calculated by Hoffer Q formula in axial length (AL) <21 mm and SRKT formula in AL ≥21 mm and then modified based on this approach: 7D initial inductive hypermetropization in children ≤1-year-old, 5D in 1–3, 3.5D in 3–5, 2.5D in 5–7, 1.5D in 7–9, 1D in 9–10, and 0 in children >10 years old. Results: The mean age of all children at surgery time was 5.85 ± 4.56 years (range: 1–178 months). There was a mean myopic shift of −6.379 D in the ≤1 year, −5.532 in the 1–3, −3.194 in the 3–5, −2.301 in the 5–7, −1.06 in the 7–9, −1.567 in the 9–10, and 0.114 in the >10-year-old age group. In 125 eyes (69.1%) of 181, the final SE was between −2 and +2 D, and 21 eyes (11.6%) achieved the goal of emmetropization. Mean best-corrected visual acuity logarithm of the minimum angle of the resolution was 0.30 in children ≤1 year, 0.39 in 1–3, 0.21 in 3–5, 0.18 in 5–7, 0.14 in 7–9, 0.16 in 9–10, and 0.11 in children >10 years old. Conclusion: This study shows a larger myopic shift in younger children. Using our approach, all age groups could finally achieve acceptable final refraction.

[PMID: 34759662 PMCID: PMC8547672 DOI: 10.4103/meajo.meajo_441_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Revised: 04/22/2021] [Accepted: 08/08/2021] [Indexed: 11/06/2022] Open
Abstract
PURPOSE: The purpose of this study is to compare the anatomical and visual outcomes of scleral buckle (SB) surgery with the pars plana vitrectomy (PPV) in the management of chronic rhegmatogenous retinal detachment. METHODS: This cohort study included patients who underwent surgical repair SB group and PPV group for chronic retinal detachment during 2014–2018 at the King Khalid Eye Specialist Hospital, Riyadh. The anatomical and functional success rate at 12 months after surgery was compared in two groups. Cox regression and linear regression analysis were performed to identify the predictor of anatomical and functional outcomes, respectively. Need for second surgery was also evaluated. RESULTS: Our cohort had 68 eyes in SB and 64 eyes in PPV group. Eyes that underwent PPV were more likely to develop retinal detachment over 12 months than those that underwent SB surgery (adjusted heart rates 2.11, 95% confidence interval [CI], 0.95–4.64 P = 0.065). A multivariable linear regression analysis did not reveal a significant association between the surgery type and change in visual acuity (beta coefficient, 0.002; 95% CI,−0.184, 0.189 for specific bread volume; P = 0.979). A higher percentage of eyes in the PPV group compared with those in the SB surgery group required secondary surgery (39.1% vs. 22.1%; P = 0.034). CONCLUSION: Scleral buckling surgery showed a better single surgery anatomic success rate as compared to PPV in the management of chronic primary rhegmatogenous retinal detachment. The functional outcome of the two procedures was comparable.

The Influence of COVID-19 Lockdown in Jordan on Patients with Diabetic Retinopathy: A Case-Control Study. Ther Clin Risk Manag 2021; 17:1011-1022. [PMID: 34584415 PMCID: PMC8462094 DOI: 10.2147/tcrm.s316265] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 08/06/2021] [Indexed: 12/16/2022] Open
Abstract
Background Diabetic retinopathy (DR) is a leading cause of vision impairment in working-age adults. Patients with DR need extensive follow-ups with timely proper treatment. In Jordan, a complete lockdown was decided during the COVID-19 pandemic including the closure of outpatients' clinic. In this study, we assess the effect of the lockdown on the progression and visual outcome for patients with DR who had interruption in their plan. Methods Retrospectively, we identified all patients who were scheduled for procedures for the management of diabetic retinopathy (DR) during the COVID-19-related quarantine period in Jordan from March 16th to June 6th, 2020. All demographics and clinical data, procedure information, and visual outcome were collected. Another control group of patients with similar characteristics who were scheduled for procedures related to DR before the COVID-19 pandemic from October 15th to December 31st, 2019 were included. Results One hundred and thirty-seven eyes planned for procedures from 89 patients were included. The case group comprises 56 eyes (40.9%). The mean age of the patients was 61.4 years. The right eye was involved in 69 procedures (50.4%). The mean change in visual acuity for the case group in the procedure eye was 0.176 in LogMAR (drop of almost 9 LogMAR letters) and the mean change in visual acuity for the control group in the procedure eye was -0.103 LogMAR (gain of about 5 LogMAR letters). Also, the central subfield thickness (CST) values were significantly worse in the case group. Furthermore, patients in the case group had significantly more disease progression (new findings and worsening of the already established findings). Conclusion Interrupting the important procedures for DR patients and delaying their follow-up may adversely affect their visual outcome. National decisions should consider conducting these procedures and exempt those patients from any lockdown with proper precautions. Moreover, certain measures would be considered, such as treat-and-extend protocol, home screening and portable OCT examination, and newer long-acting anti-VEGF drugs.

Therapeutic prognostic factors associated with retinal detachment and visual outcomes in acute retinal necrosis. Clin Exp Ophthalmol 2021; 50:40-49. [PMID: 34585833 DOI: 10.1111/ceo.14016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 09/18/2021] [Accepted: 09/25/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Acute retinal necrosis (ARN) is a fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of vision loss. Prognostic factors associated with the treatment of ARN have not been comprehensively identified. This study aimed to determine therapeutic prognostic factors associated with long-term clinical outcomes in eyes with ARN. METHODS This retrospective cohort study included patients with ARN who were treated between 2005 and 2019 in two tertiary ophthalmology departments in Seoul, Korea. Multiple logistic regression analysis was performed to investigate prognostic factors associated with late-onset retinal detachment (RD) and vision loss (<20/200). RESULTS Sixty-one eyes with ARN with an average follow-up of 63.5 months were included. Surgical intervention of vitrectomy (odds ratio [OR], 0.04; 95% confidence interval [CI], 0.004-0.47) and intraoperative prophylactic laser use (OR, 0.14; 95% CI, 0.02-0.81) were independently associated with a decreased risk of late RD. The factors independently associated with an increased risk of vision loss were worse initial visual acuity (OR, 3.28; 95% CI, 1.50-7.21), zone 1 involvement of necrotic retinitis (OR, 10.84; 95% CI, 1.62-72.41), and late-onset RD (OR, 5.38; 95% CI, 1.92-31.54). CONCLUSION Vitrectomy and/or prophylactic intraoperative laser treatment may be effective treatment options in preventing delayed RD associated with an increased risk of vision loss in eyes with ARN.

Case Report: Phototherapeutic Keratectomy for Band Keratopathy Secondary to Chemo-Laser-Cryotherapy for Retinoblastoma. Front Med (Lausanne) 2021; 8:668762. [PMID: 34513859 PMCID: PMC8423897 DOI: 10.3389/fmed.2021.668762] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 08/04/2021] [Indexed: 12/03/2022] Open
Abstract
Purpose: To report the clinical outcomes of phototherapeutic keratectomy (PTK) for pediatric band keratopathy after treatment for retinoblastoma. Methods: A 5-year-old boy presented with a 2-year history of poor visual acuity and a horizontal gray-white band across the central cornea in the right eye. He was diagnosed with band keratopathy after chemo-laser-cryotherapy for retinoblastoma. The band keratopathy was treated via PTK using the Mel-90 excimer laser with an optical treatment zone of 7.0 mm and ablation depth of 120 μm. The patient was followed at 1 week and 3 months postoperatively. Results: Surgery and postoperative follow-up were uneventful. At the 3-month follow-up, the uncorrected distant visual acuity of the right eye improved to 20/125, and the corrected distance visual acuity improved to 20/70 with a refraction of +10.00 D/−2.50 DC × 15. The clarity of the ablated area was evidently improved. The central corneal thickness decreases from 612 to 584 μm. The optical coherence tomography showed the thin band of hyperreflectivity in the ablated area disappeared, corneal transparency improved and the corneal surface smoothened. Conclusions: PTK is a safe and effective procedure to treat band keratopathy following treatment of retinoblastoma in children. Early intervention can reduce the risk of developing deprivation amblyopia.

Comparison of visual outcomes after non-toric and toric implantable collamer lens V4c for myopia and astigmatism. Acta Ophthalmol 2021; 99:511-518. [PMID: 33084228 DOI: 10.1111/aos.14652] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 09/23/2020] [Indexed: 11/29/2022]
Abstract
PURPOSE To evaluate the visual quality of myopic patients after non-toric versus toric implantable collamer lens (ICL and TICL, respectively) V4c, and to investigate the potential risk factors of postoperative night vision disturbances. METHODS This prospective cohort study included 42 eyes of 21 patients treated with ICL and 46 eyes of 23 patients treated with TICL. Refractive parameters and ocular aberrations were examined before and 6 months after surgery. Subjective quality of vision was scored by a validated questionnaire. RESULTS The efficacy index at 6 months was 1.14 ± 0.20 for ICL and 1.17 ± 0.16 for TICL; the safety index was 1.20 ± 0.17 for ICL and 1.20 ± 0.19 for TICL. The root mean square of total higher-order aberrations (HOAs) and trefoil was significantly increased, and no statistical differences between groups were detected in HOA changes. Many patients reported haloes (85.7% for ICL and 100% for TICL) and glare (76.2% for ICL and 65.2% for TICL), but most (94.4% for ICL and 95.5% for TICL) were satisfied or very satisfied with visual outcomes. Implantable collamer lens (ICL) toricity was the risk factor for frequency (OR = 2.81, p = 0.01), severity (OR = 3.85, p = 0.003) and bothering effect (OR = 2.89, p = 0.01) of haloes. CONCLUSIONS Implantable collamer lens and TICL provided comparable efficacy, safety and predictability, induced acceptable level of HOAs and achieved high satisfaction in correcting myopia and myopic astigmatism. Although not severe, haloes and glare have a non-negligible prevalence and ICL toricity is a potential risk factor of haloes.

Abstract
Purpose To describe the epidemiology of open globe injuries and its prognostic factors from the perspectives of a tertiary care centre in northern Malaysia. Methods A retrospective study of open globe injuries in a period of three years between June 2017 and May 2020. Patients presenting with open globe injuries were identified and recruited from hospital census. Case records were retrieved and analysed after recruitment. Results A total of 114 patients with 118 open globe injuries were included in the study. Four patients had bilateral eye involvement. Men were found to have seven and a half times higher rate of ocular injuries than women. The predominant age group of ocular trauma presentation was in younger adults between the age of 21 and 30 years old. Work-related injuries account for almost half of the globe injuries (48.7%) followed by motor vehicle accident-related, domestic accident-related, and others. The significant factors related to the visual outcome are presenting visual acuity (VA), presence of relative afferent pupillary defect (RAPD) and vitreous loss. Conclusion The factors related to visual outcomes in this study may aid the clinician in determining the visual prognosis of ocular injuries. Young working males were the most susceptible group to sustain penetrating ocular injuries due to their job nature. Health education and safety at workplace are essential to reduce the occurrence of ocular injuries.

Abstract
Background The quality of cataract surgery can be measured by visual outcome, which is sometimes limited by intraoperative complications, most commonly posterior capsular rupture. Aims The aim of the study was to assess visual outcome at the last visit (≥8 weeks) following posterior capsule rupture (PCR) in patients who had manual small incision cataract surgery (MSICS) managed without access to an automated vitrector. Methods A review of medical records of all manual small incision cataract surgeries performed between January 2013 and December 2016 at the National Eye Centre, Kaduna, Nigeria was conducted. Descriptive statistics and logistic regression analysis were performed using STATA 14.0 to examine risk factors for the development of a poor visual outcome and to assess the impact of PCR on development of poor visual outcome. Results In total, 405 patients were operated on with MSICS (50.6% males). Mean age was 62.4 (SD 12.6) years. PCR was the most common complication (n = 19 (4.7%)). The proportion of good outcomes (≥6/18) rose from 12.4% non-PCR and 0.0% for those with PCR at day 1 postoperative review, to 71.5 and 26.3%, respectively, by final follow up (P = 0.001). Patients with PCR were 7.0 (P = 0.0001) times more likely to have borderline/poor visual outcome (<6/18) compared to those without PCR. Age >60 years increased the odds of borderline/poor by 1.4 times (P = 0.002). Conclusion PCR significantly affects the visual outcome of cataract patients in settings with no facilities for automated vitrectomy. Minimizing complications will improve visual outcome of cataract patients and increase uptake of cataract surgical services.

Can the postoperative follow-up visit be deferred up to four weeks after an uneventful cataract surgery? - A randomized controlled trial. Indian J Ophthalmol 2021; 69:1409-1413. [PMID: 34011710 PMCID: PMC8302296 DOI: 10.4103/ijo.ijo_2390_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
Purpose: The aim of this study was to compare the postoperative visual outcome after a Day 0 examination in patients with two follow-ups, one between Day 3 to Day 7 and other between Day 25 to Day 30 to those with a single ophthalmic follow-up directly after 25–30 Days and to assess the safety of deferral of the first follow-up visit at 1 week. Methods: Randomized Controlled Trial was conducted at a tertiary eye care hospital, with 848 patients enrolled for the study. Patients meeting the inclusion criteria were selected. Their pre-operative and post-operative data was collected and the patients were divided into groups based on the type of cataract surgery and the postoperative follow-up protocol through randomization. Results: No significant difference was observed in the postoperative visual outcome in patients that underwent postoperative review at Day 3–7 and Day 25–30 as opposed to those that followed up directly at Day 25–30 after a mandatory Day 0 examination for all patients. Conclusion: In patients with no preexisting ocular or systemic comorbidity undergoing an uneventful cataract surgery, the postoperative follow-up visit can be safely deferred until 4 weeks, without any impact on the postoperative visual outcome, thereby conserving the available resources which can be deviated towards better eye care services.

Clinical characteristics and prognostic factors for visual outcome in 669 patients with intraocular foreign bodies. Int J Ophthalmol 2021; 14:759-765. [PMID: 34012893 DOI: 10.18240/ijo.2021.05.18] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 08/06/2020] [Indexed: 02/08/2023] Open
Abstract
AIM To describe the clinical characteristics and analyze prognostic factors that influence visual outcome in 669 patients with intraocular foreign bodies (IOFBs). METHODS Medical records of 669 patients with IOFBs from West China Hospital were reviewed. Best corrected visual acuity (BCVA) values were recorded using standard Snellen acuity chart and were converted to logarithm of the minimum angle of resolution (logMAR) scale for statistical analysis. The visual outcome was defined by the final BCVA (excellent visual outcome: final BCVA of 20/40 or better; poor visual outcome: final BCVA less than 20/200). Statistical analysis of collected data was performed using IBM SPSS Statistics version 23. A 2-tailed P value of less than 0.05 was considered statistically significant throughout the study. RESULTS The average age ranged from 1 to 79 years old (mean age, 34.8±12.7 SD) and the majority of patients were men (626, 93.6%). The major cause of ocular injury was hammering (383, 57.2%). Almost all the patients (97.8%) underwent surgeries (97.8%) and the average time interval between injury and surgery was 26.4±322.3d (0-7300), while 327 patients received surgeries within 24h (48.9%) and 590 patients received surgeries within seven days (88.2%) after IOFBs injury. The poor BCVA was associated with older age (P=0.013), larger IOFBs size (P<0.001), presence of complications (P<0.001) and worse presenting BCVA (P<0.001). On the contrary, younger age (P=0.005), smaller IOFBs size (P<0.001), absence of complications (P<0.001) and better presenting BCVA (P<0.001) were considered to relate to excellent BCVA. CONCLUSION Multiple prognostic factors may influence the final visual outcome, including age, size of IOFBs, complications and presenting BCVA. Meanwhile, further education and promotion on eye protection should be taken for the improvement on self-protection and self-health awareness.

The predictive value of intraoperative visual evoked potential for visual outcome after extended endoscopic endonasal surgery for adult craniopharyngioma. J Neurosurg 2021; 135:1714-1724. [PMID: 33962373 DOI: 10.3171/2020.10.jns202779] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Accepted: 10/01/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Due to the proximity of craniopharyngioma to the optic apparatus, one of the most common complications after surgery is visual deterioration. Intraoperative visual evoked potential (VEP), as a means of real-time visual function monitoring, has been integrated into transsphenoidal surgery for pituitary adenoma to predict postoperative visual outcome. Compared with pituitary tumor, craniopharyngioma often adheres to optic nerves, with increased risk of postoperative visual impairment. Furthermore, extended endoscopic endonasal surgery (EEES) can provide direct visualization of the surgical plane between the craniopharyngioma and the optic nerves, which contributes to analysis of the mechanism of real-time VEP changes during surgery. Therefore, VEP monitoring applied during EEES for craniopharyngioma may have more clinical value. However, only 9 patients who underwent EEES with VEP monitoring for craniopharyngioma have been sporadically reported to date. In this paper, the authors present the largest series to date analyzing the clinical value of VEP to predict postoperative visual outcome in adult patients with craniopharyngioma. METHODS Sixty-five adult patients who underwent EEES with intraoperative VEP monitoring for primary craniopharyngioma were retrospectively reviewed. The association between changes in VEP amplitude and postoperative visual outcome was determined. In addition, other potential prognostic factors with regard to postoperative visual outcomes were included in the analysis. RESULTS Gross-total resection was achieved in 59 patients (90.8%). Reproducible and stable VEP was recorded in 128 of 130 eyes (98.5%). During surgery, VEP remained stable in 108 eyes, 10 (9.3%) of which had new visual acuity (VA) and/or visual field (VF) defects after surgery. Transient VEP decrease was recorded in 15 eyes, 4 (26.7%) of which had visual deterioration. Of the 5 eyes with permanent VEP decrease, 3 (60%) experienced postoperative visual impairment. Permanent VEP decrease (OR 19.868, p = 0.007) and tight adhesion (OR 6.104, p = 0.040) were independent adverse factors for postoperative VA deterioration. Tight adhesion (OR 7.150, p = 0.002) and larger tumor volume (OR 1.066, p = 0.001) were significant risk factors for postoperative VF defects. CONCLUSIONS Intraoperative VEP monitoring can serve as a real-time warning to guide surgeons to avoid postoperative visual impairment. It effectively predicted VA changes in adult patients with craniopharyngioma after EEES. Tight adhesion and larger tumor volume were also strong predictors of postoperative visual impairment.
