Retrolental Bullous Retinal Detachment as the Presenting Feature of Vogt-Koyanagi-Harada Disease in an Elderly Indian Female: Diagnostic and Therapeutic Challenge

PURPOSE

To report an atypical case of Vogt-Koyanagi-Harada (VKH) disease with retrolental bullous retinal detachment (RD).

METHODS

A case report.

CASE

A 67-year-old Indian woman with bilateral, gradual visual loss presented with both eyes light perception, keratic precipitates, 2+ cells and bullous RD, which was retrolental in right eye (RE). Systemic investigations were unremarkable. She received systemic corticosteroids, and underwent pars plana vitrectomy (PPV) in left eye (LE). Intraoperatively, sunset glow with leopard-spot fundus were suggestive of VKH disease. Immunosuppressive therapy was added. At 2 years, vision was 3/60 in RE and 6/36 in LE. The LE retina reattached immediately following surgery, while RE exudative RD resolved very gradually following corticosteroids.

SUMMARY

This report illustrates diagnostic as well as therapeutic challenge in VKH disease presenting with retrolental bullous RD. PPV provided a faster anatomical and functional restoration than systemic corticosteroid therapy alone, which has potential adverse effects in the elderly.

Surgical management of a case of giant retinal tear with closed funnel retinal detachment in a pediatric patient

BACKGROUND

A 7-year-old male child was brought by his parents with a complaint of low vision in both eyes for 2 months. The child had low vision in both the eyes for 1.5 years, but the parents noticed when it worsened further 2 months back, leading to profound vision loss. On ophthalmic evaluation, the child did not perceive light in the right eye. Furthermore, anterior segment examination showed complicated cataract and open funnel retinal detachment with intra-retinal cysts in ultrasound (USG) B scan. In the left eye, he could appreciate light but with poor fixation. Fundus evaluation of the left eye showed total retinal detachment on indirect ophthalmoscopy, which was confirmed on USG B scan. Since the right eye had poor visual potential, no intervention was done. The left eye underwent pars plana vitrectomy with silicone oil tamponade, which led to successful anatomical outcomes. The immediate and late postoperative periods were uneventful, and the child was kept under follow-up and was observed closely.

PURPOSE

To educate regarding the surgical management of giant retinal tears in a pediatric patient.

SYNOPSIS

To inform regarding the surgical challenges faced and steps adopted to manage such cases.

HIGHLIGHTS

Through this case, we want to highlight the challenges faced, such as delayed presentation, difficult preoperative evaluation, intraoperative difficulties such as mobile retina, absence of posterior vitreous detachment, and tenacious vitreous gel. We also want to emphasize on the steps taken to overcome the challenges.

CONCLUSION

In such challenging situations, effective planning, careful manipulation, and persistence are essential for success.

RECURRENT OPTIC DISC PIT MACULOPATHY DUE TO VALSALVA'S MANEUVER

PURPOSE

We report a patient with recurrent optic disc pit (ODP) maculopathy after Valsalva's maneuver and discuss its pathophysiology. We also hypothesize the role of Valsalva's maneuver in its genesis.

METHOD

Case report of one patient, male, 12 years old.

RESULTS

Serous retinal detachment may occur in association with the ODP, a developmental anomaly of the optic nerve head. Histopathologically, it consists of a dysplastic retina herniation into a pocket extending posteriorly through a defect in the lamina cribrosa into the subarachnoid space. These three different compartments-intraocular space, optic nerve head, and subarachnoid space-and the dynamic interactions among them should be understood as the key factors for the occurrence of ODP-related serous retinal detachment.

CONCLUSION

Based on the possibility that serous retinal detachment secondary to the ODP could be related to the Valsalva's maneuver, we strongly recommend that patients with ODP be advised to avoid intense physical or work activities that may increase abdominal, thoracic, and cerebral pressure and to refrain from playing wind instruments to avoid pretreatment, per treatment, and post-treatment intercurrences.

SF 6 COMPARED WITH C 2 F 6 FOR INFERIOR RHEGMATOGENOUS RETINAL REPAIR : The Manchester Pseudophakic Retinal Detachment Study

PURPOSE

To compare SF 6 relative with C 2 F 6 in the anatomical and functional outcomes following pars plana vitrectomy for uncomplicated primary pseudophakic rhegmatogenous retinal detachment with inferior causative breaks.

METHODS

This is a retrospective, comparative study on eyes with pseudophakic rhegmatogenous retinal detachment with inferior causative breaks that had small-gauge pars plana vitrectomy repair using SF 6 and C 2 F 6 tamponade between 2011 and 2020 at a tertiary centre in the United Kingdom. Primary outcome was single surgery anatomical success, and the secondary outcome was best-corrected visual acuity. Propensity score matching, using preoperative findings as covariates to account for relevant confounders, was performed.

RESULTS

From 162 pseudophakic rhegmatogenous retinal detachment eyes with inferior causative breaks, the median (interquartile range) follow-up was 82 (52-182) days. The single surgery anatomical success was 156 (96.3%) overall: 47 of 47 (100.0%) and 109 of 115 (94.8%) in the SF 6 and C 2 F 6 groups, respectively ( P = 0.182). Relative to the SF 6 group, the C 2 F 6 group had a higher mean number of tears (SF 6 : 3.1[2.0], C 2 F 6 : 4.5[2.7], P = 0.002) and greater retinal detachment extent (SF 6 : 5.3[2.9], C 2 F 6 : 6.2[2.6] clock hours, P = 0.025). Following propensity score matching analysis, 80 eyes were matched with 40 in each group to homogenize preoperative factors. No significant difference was found in single surgery anatomical success and best-corrected visual acuity between the groups following propensity score matching.

CONCLUSION

Primary pars plana vitrectomy with gas tamponade leads to a high single surgery anatomical success rate in uncomplicated pseudophakic rhegmatogenous retinal detachment with inferior causative breaks with no additional benefit associated with long-acting tamponade when comparing C 2 F 6 with SF 6 .

SS OCT and OCT-A Findings in Convalescent Inactive Vogt-Koyanagi-Harada Disease

PURPOSE

This study aimed to determine predictive factors for low final visual acuity in patients with inactive Vogt-Koyanagi-Harada (VKH) disease using Swept-source OCT and OCT-angiography (OCT-A).

METHODS

We conducted a prospective longitudinal study, including 21 patients (42 eyes), who were followed up for the first 24 months after disease onset. Patients were included at the acute phase and subsequently treated. Sequential qualitative and quantitative changes in OCT and OCT-A were assessed. Analytical statistical methods were employed to determine predictive factors for final visual acuity.

RESULTS

Structural alterations including focal parafoveal outer nuclear layer atrophy, ellipsoid zone disruption, interdigitation zone disruption, and irregular and thickened retinal pigment epithelium line were observed in 57.1% of eyes at month 3, with no significant improvement over time. The presence of flow voids at months 6, 12, and 24 was significantly associated with low final visual acuity. Serous retnal detachment at presentation emerged as an independent risk factor for structural changes detected by SS-OCT during the first 2 years of the disease. Optic disc edema was predictive factor for both structural SS-OCT and OCT-A changes.

CONCLUSION

This study underscores the importance of monitoring flow voids to predict final visual acuity and highlights the impact of serous retinal detachment at presentation on structural changes in patients with inactive VKH disease.

ADDITIONAL PNEUMATIC RETINOPEXY IN PATIENTS WITH PERSISTENT RETINAL DETACHMENT AFTER SCLERAL BUCKLING

PURPOSE

To investigate the efficacy, safety, and indications for additional pneumatic retinopexy (PR) in patients with persistent retinal detachment after scleral buckling.

METHODS

This retrospective study included patients who underwent additional PR after scleral buckling for primary rhegmatogenous retinal detachment (n = 78). We defined "inadequate buckle" as retinal detachment persistence because of low buckle height despite accurate buckle placement and "buckle misplacement" as an uncovered tear because of incorrect buckle placement.

RESULTS

The anatomical success rate after additional PR was 52.6%. Development of proliferative vitreoretinopathy Grade B (hazard ratio, 5.73; P < 0.001) and inferior retinal tears (hazard ratio, 2.12; P = 0.040) were significant risk factors for anatomical failure. The most common cause of anatomical failure was proliferative vitreoretinopathy (19 of 37; 51.4%), and epiretinal membrane formation was a common complication after additional PR (22 of 78; 28.2%). The anatomical success rate with additional PR was significantly higher in the inadequate buckle group than in the misplacement group (8 of 9 [88.9%] vs. 1228 [42.9%]; P = 0.023).

CONCLUSION

Development of proliferative vitreoretinopathy Grade B and inferior retinal tears were significantly associated with anatomical failure after additional PR. Additional PR may benefit patients with superior retinal tears or low buckle height and those without proliferative vitreoretinopathy.

GORE-TEX SUTURE-ASSOCIATED ENDOPHTHALMITIS IN A SCLERAL-SUTURED INTRAOCULAR LENS

PURPOSE

To describe a unique case of Gore-Tex (Gore Medical, AZ) suture-associated delayed-onset endophthalmitis in a patient with a history of scleromalacia, pathologic myopia, multiple prior vitrectomies in the setting of a scleral-sutured intraocular lens (IOL).

METHODS

A 69-year-old man complained of blurry vision and eye pain 21 months after implantation of a scleral-sutured IOL and was found to have an exposed Gore-Tex suture with scleromalacia, vision loss to hand motion, a hypopyon, and vitritis. He was diagnosed with culture-positive endophthalmitis. He had a previous history of a rhegmatogenous retinal detachment repair and subsequent dislocated IOL in this eye treated with a scleral-sutured IOL. A vitreous tap and injection of broad-spectrum antibiotics and suture removal at the slit lamp were performed at the time of presentation. One week later, he underwent pars plana vitrectomy and removal of the IOL.

RESULTS

After the tap and inject and subsequent lens removal, his vision has returned to his preoperative vision of 20/100 with refraction.

DISCUSSION

Gore-Tex suture is a nonabsorbable and flexible option with great tensile strength that has emerged as a favored alternative to polypropylene for the use in transscleral fixated IOLs. Although endophthalmitis and suture erosion are known complications of this procedure, this report describes one of the first cases of Gore-Tex suture-associated endophthalmitis.

PERSISTENT SUBRETINAL FLUID AFTER VITRECTOMY FOR MACULAR HOLE-ASSOCIATED RETINAL DETACHMENT

PURPOSE

To evaluate the incidence, associated factors, and outcome of persistent subretinal fluid (SRF) after vitrectomy for macular hole-associated retinal detachment (MHRD).

METHODS

A total of 158 eyes from 156 patients with MHRD who achieved macular hole closure after primary vitrectomy were included in the analysis; persistent SRF was defined as the presence of SRF for more than 1 month after first surgery. Preoperative and postoperative parameters were analyzed for their relationship with SRF development.

RESULTS

Persistent SRF was observed in 19 eyes (12.0% of 158) postoperatively. Seven eyes (36.8% of 19) with persistent SRF eventually displayed complete absorption during follow-up. Univariate analysis revealed that eyes with persistent SRF were statistically associated with internal limiting membrane inverted flap, duration of symptoms, tamponade (perfluoropropane/silicone oil: 14/5 vs. 35/104, P < 0.001), and MHRD subtype (Type 1/Type 2/Type 3: 15/4/0 vs. 60/40/39, P = 0.003). In multivariate analysis, only internal limiting membrane inverted flap (odds ratio, 15.778, 95% confidence interval, 3.170-78.523; P = 0.001) was positively associated with persistent SRF. There were no significant differences in best-corrected visual acuity improvement ( P = 0.425) between the SRF involved foveal and without involved foveal groups and no significant differences between the SRF complete absorption and incomplete absorption groups.

CONCLUSION

Absorption of persistent SRF may be more difficult in MHRD eyes than in ordinary rhegmatogenous retinal detachment eyes. The internal limiting membrane inverted flap in MHRD was associated with a greater likelihood of persistent SRF. The location and incomplete absorption of persistent SRF did not seem to be associated with the final visual outcome.

Giant retinal pigment epithelial tear following photodynamic therapy for the bullous variant of central serous chorioretinopathy: A case report

RATIONALE

The bullous variant of central serous chorioretinopathy (CSC) is a severe form of chronic CSC. Patients with the bullous variant of CSC have an increased risk of experiencing multiple pigment epithelial detachments (PEDs) and retinal pigment epithelium (RPE) tears. Photodynamic therapy (PDT) is a treatment for the bullous variant of CSC. RPE tear is a possible postoperative complication of PDT for eyes with PEDs. To our knowledge, no cases of giant RPE tears following PDT for the bullous variant of CSC have been reported previously. This case report presents the first instance of a giant RPE tear after half-time PDT for the bullous variant of CSC, accompanied by a series of images depicting the tear development.

PATIENT CONCERNS

A 63-year-old male patient presented with rapidly deteriorating vision in his left eye over a 3-month period. He also reported a previous episode of vision loss in his right eye 2 years prior. Best-corrected visual acuity (BCVA) in the left eye was 0.2.

DIAGNOSIS

The right eye was diagnosed with chronic non-bullous CSC, while the left eye was diagnosed with the bullous variant of CSC with a large PED.

INTERVENTIONS

Half-time PDT was administered to the left eye.

OUTCOMES

One month after half-time PDT, a giant RPE tear exceeding 3 clock-hours in size was confirmed in the lower temporal quadrant of the left eye. Three months after the initial half-time PDT, a second half-time PDT was performed owing to recurrent retinal detachment. Two months after the second half-time PDT, the retinal detachment resolved, and BCVA improved to 0.4, 6 months after the second half-time PDT.

LESSONS

In cases where the bullous variant of CSC is complicated by extensive PED, clinicians should consider the potential development of a giant RPE tear as a treatment complication.

Vasoproliferative Tumor Secondary to Sarcoidosis-Associated Intermediate Uveitis

We report the visual and clinical outcomes of a middle-aged woman who presented with exudative retinal detachment (ERD) secondary to a vasoproliferative tumor (VPT) in an eye with sarcoidosis-associated intermediate uveitis. A 55-year-old woman previously diagnosed with sarcoidosis presented with decreased vision in the left eye (LE). Visual acuity in the LE was counting fingers. She had active vitritis, and a peripheral retinal vascular mass was noted in the superotemporal periphery. The mass was associated with ERD involving the posterior pole. The patient was managed with systemic and intravitreal steroids, and cyclosporine was subsequently added as a steroid-sparing agent. Because of recurrence of ERD, the patient underwent pars plana vitrectomy, and cryotherapy and laser photocoagulation were applied to the VPT. Two months postoperatively, visual acuity in the LE improved to 6/10. There was marked regression of the VPT and total resolution of the ERD. In conclusion, we report a favorable visual and clinical outcome in a patient with VPT-associated ERD who responded to a combination of medical therapy and surgical intervention. VPT may lead to different remote complications, so timely diagnosis of these tumors and proper management of their complications is warranted.

Macular edema after surgery to treat rhegmatogenous retinal detachment: 1-year follow-up, incidence, and associated risk factors

PURPOSE

To clarify the postoperative incidence of macular edema in patients undergoing surgery to repair rhegmatogenous retinal detachment and identify the associated risk factors.

METHODS

In this prospective, observational study, 79 patients who underwent surgery to correct rhegmatogenous retinal detachment using pars plana vitrectomy with silicone oil injection were analyzed. Patients were followed up postoperatively at 7, 30, 90, 180, and 365 days. At each visit, optical coherence tomography was performed to assess the presence or absence of macular edema. were analyzed as possible risk factors for macular edema: age, sex, macular status (attached or detached), presence of vitreoretinal proliferation, history of previous intraocular surgery, reported time of symptoms suggestive of rhegmatogenous retinal detachment up to the date of surgery, and the surgical modality performed.

RESULTS

The 1-year macular edema prevalence rate was 26.6%. In the adjusted analysis, older patients had a higher risk of macular edema, and each 1-year increase in age increased the risk of macular edema by 6% (95% confidence interval = 1.00-1.12). The macular status, vitreoretinal proliferation, the surgical technique used, prior intraocular surgery, and the intraocular lens status were not identified as risk factors. However, the incidence of macular edema increased up to 180 days after surgery, peaking at 10.6%, and then decreased until 365 days after surgery.

CONCLUSION

Macular edema was a common complication after surgery to treat rhegmatogenous retinal detachment, with its incidence peaking between 30 and 180 days after surgery. Age was an important risk factor for macular edema in this cohort.

Giant retinal pigment epithelium tears with membranous nephropathy: a case report and literature review

BACKGROUND

Kidney and eye diseases may be closely linked. Tears of the retinal pigment epithelium (RPE) have been reported to be related to kidney diseases, such as IgA nephropathy and light-chain deposition disease. However, pigment epithelium tears associated with membranous nephropathy have not been reported or systematically analysed.

CASE PRESENTATION

A 68-year-old man presented with decreased right eye visual acuity. Optical coherence tomography (OCT) revealed cystic macular edema, localized serous detachment of the retina and loss of the outer retinal structure in the right eye and retinal pigment epithelium detachment (PED) combined with serous detachment of the retina in the left eye. Fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) revealed giant RPE tears in the right eye and exudative age-related macular degeneration in the left eye. The patient also suffered from severe membranous nephropathy-autoimmune glomerulonephritis. Renal biopsy immunofluorescence revealed a roughly granular pattern, with immunoglobulin G (IgA), immunoglobulin G (IgG), IgM, complement C3(Components 3), λ light chain and κ light chain subepithelial staining.

CONCLUSIONS

It is hypothesized that severe membranous nephropathy caused immune complex deposition on the surface of Bruch membrane, resulting in weakened adhesion between the RPE and Bruch membrane and impaired RPE pump function, combined with age-related macular degeneration, leading to giant RPE tears in the right eye. Close attention should be given to the ocular condition of patients with membranous nephropathy to facilitate timely treatment and avoid serious consequences.

Traumatic terson syndrome with a peculiar mass lesion and tractional retinal detachment: a case report

BACKGROUND

To report a case with bilateral Terson syndrome presented with a unique mushroom-like mass lesion on the optic disc along with proliferative vitreoretinopathy and tractional retinal detachment.

CASE PRESENTATION

A 33-year-old man was injured during a traffic accident and had diffuse brain swelling and intraocular hemorrhage. Poor vision in both eyes was noted after the patient regained consciousness. B-scan ultrasonography showed extensive vitreous opacity with a posterior vitreous detachment and without obvious retinal detachment. Vitrectomy was performed in both eyes five months after the accident. After clearing up the vitreous opacity, a peculiar pigmented mushroom-like mass lesion was noted in the posterior pole and had severe adhesion to the underneath optic disc. Extensive multilayered peripapillary epiretinal membrane was found covering the posterior pole and led to tractional retinal detachment around the macula. The mass was presumed to be an organized vitreous hemorrhage originated from the optic disc. The extensive and adherent epiretinal membrane together with the mass lesion were removed as much as possible and silicon oil was injected for tamponade. However, in the right eye, the retina redetached under silicon oil, whereas in the left eye, his vision improved to 20/100.

CONCLUSIONS

Terson syndrome usually has a favorable prognosis but may be complicated by proliferative vitreoretinopathy and tractional retinal detachment. Careful monitoring is warranted and early vitrectomy should be considered in cases suspecting additional pathologies.

Brolucizumab in recalcitrant neovascular age-related macular degeneration-real-world data in Chinese population

This retrospective study aimed to determine the short-term efficacy and safety of brolucizumab treatment for recalcitrant neovascular age-related macular degeneration (nAMD) in a real-world setting in Taiwan. Recalcitrant nAMD patients who were treated with brolucizumab from November 2021 to August 2022 at Taipei Veterans General Hospital were included. Patients were followed for 3 months after switching to brolucizumab. The primary outcomes were changes in mean best-corrected visual acuity (BCVA) and central retinal thickness (CRT) from baseline to the third month. The secondary outcomes included the incidence of intraocular inflammation (IOI), proportion of patients with subretinal and intraretinal fluid (SRF and IRF), and change in pigment epithelial detachment (PED) height from baseline to the third month. The significance level was considered as p < .05 in all tests. A total of 38 patients (40 eyes) with a mean (±SD) age of 76.3 (±10.84) years were included. The baseline BCVA was 0.92±0.64 logMAR, and the CRT and PED height were 329.0±171.18 and 189.8±114.94 um, respectively. The patients had a significant reduction in CRT and resolution of IRF and SRF from baseline to the third month. There were numerical improvements in mean BCVA and PED height, but they were not significant. The percentages of achieving at least 0.1, 0.2, and 0.3 logMAR (equivalent to 5, 10, 15 ETDRS letters) visual gain were 50%, 37.5%, and 30%, respectively, during the first 3 months of follow-up. No IOI occurred in these patients. This study demonstrated that brolucizumab had good short-term structural and functional efficacy in recalcitrant nAMD patients.

A case report: co-occurrence of probable Vogt-Koyanagi-Harada disease and diabetic retinopathy

BACKGROUND

Bilateral retinal detachment and choroidal detachment in a patient are rare occurrences. The presence of bilateral diabetic retinopathy (DR) in such a case is even rarer and complicates the condition.

CASE PRESENTATION

In this study, we document a case of unconventional VKH. Manifestations in this patient included intense peripheral retinal detachment and choroidal detachment, along with vitreous opacities akin to cotton wool spots, concurrent with DR. The diagnosis was considered as probable VKH with DR. Treatment according to VKH protocols, including high-dose corticosteroids, yielded positive results.

CONCLUSIONS

VKH can co-occurrence with DR. VKH manifestations vary, and early, aggressive, and long-term treatment is essential. The complexity of treatment increases with concurrent DR, necessitating the use of immunosuppressants.

Risk factors for surgical failure after primary scleral buckling for rhegmatogenous retinal detachment

OBJECTIVE

To identify risk factors for surgical failure after scleral buckling (SB) for primary rhegmatogenous retinal detachment (RRD) repair.

DESIGN

Single-centre retrospective consecutive case series.

PARTICIPANTS

All patients who underwent SB for repair of primary RRD at Wills Eye Hospital between January 1, 2015, and December 31, 2018, were included.

METHODS

Single-surgery anatomic success (SSAS) rate and risk factors associated with surgical failure were evaluated. A multivariable logistic regression model was completed to assess the effect of demographic, clinical, and operative variables on SSAS rate.

RESULTS

A total of 499 eyes of 499 patients were included. Overall SSAS rate was 86% (n = 430 of 499). Using multivariate analysis, surgical failure was more likely in males (adjusted odds ratio [adjusted OR] = 2.98; 95% CI, 1.58-5.62; p = 0.0007) with a macula-off status on preoperative examination (adjusted OR = 2.15; 95% CI, 1.10-4.20; p = 0.03) and preoperative proliferative vitreoretinopathy (adjusted OR = 4.26; 95% CI, 1.10-16.5; p = 0.04). Time interval between initial examination and surgery (p = 0.26), distribution of buckle or band material used (p = 0.88), and distribution of tamponade used (p = 0.74) were not significantly different between eyes with and without surgical failure.

CONCLUSION

Male sex, macula-off status, and preoperative proliferative vitreoretinopathy were factors with increased odds of surgical failure after SB for primary RRD repair. Operative characteristics, such as type of band or use of tamponade, were not associated with surgical failure.

Retinal Detachments after Open-Globe Injury: Risk Factors and Outcomes

PURPOSE

To identify risk factors for retinal detachment (RD) after open-globe injury (OGI) and evaluate outcomes of RD repair after OGI.

DESIGN

Case-control study.

PARTICIPANTS

Overall, 769 patients presented with 786 OGIs, which were surgically managed with ≥ 30 days of follow-up. Of the 786 eyes, 223 developed RD, the other 551 served as controls, and RD status of 12 eyes was unknown.

METHODS

A retrospective chart review was performed of all OGIs presented to the University of Michigan between 2000 and 2022. Multivariable regression identified risk factors for RD after OGI and predictors of poor vision after RD repair. Kaplan-Meier analysis estimated time from OGI to RD.

MAIN OUTCOME MEASURE

Predictors of visual outcome after RD repair after OGI.

RESULTS

After OGI, 223 (28.4%) of 786 eyes were diagnosed with RD, with > 73% diagnosed within a month. Predictors of RD include posterior injury (zone II vs. I odds ratio [OR], 1.60 [95% confidence interval {CI}, 1.04-2.46]; P = 0.0331; zone III vs. I OR, 2.29 [1.53-3.41]; P < 0.0001), vitreous hemorrhage (OR, 2.29 [1.54-3.1]; P < 0.0001), and presenting acuity worse than count fingers (CFs) (OR, 2.65 [1.69 - 4.16]; P < 0.0001). Retinal detachment repair took place in 142 of 223 eyes. The mean logarithm of minimal angle of resolution visual acuity (VA) improved from 2.3 ± 0.8 to 1.7 ± 0.9 after RD repair at 6-month follow-up, with 51.2% of eyes achieving CF or better vision. Single surgery anatomic success rate was 69.7% and final anatomic success was 88%. Predictors of vision worse than CF include history of ocular surgery (OR, 0.32 [0.11-0.94]; P = 0.039), proliferative vitreoretinopathy (PVR; OR, 0.39 [0.16 - 0.92]; P = 0.032), aphakia (OR, 0.25 [0.08 - 0.77]; P = 0.016), and redetachment (OR, 0.26 [0.1 - 0.63]; P = 0.003).

CONCLUSIONS

Most RD occur within the first month after OGI. Patients with posterior injuries, vitreous hemorrhage, or poor presenting VA were more likely to develop RD after OGI. Anatomic success was achieved in the majority, as was final VA of CF vision or better. History of ocular surgery, PVR at time of repair, aphakia, and redetachment were risk factors for a poor outcome.

Choroidal Effusion with Exudative Retinal Detachment following Non Perforating YAG-Laser Peripheral Iridotomy: A Case Report

AIM

To report a case of choroidal effusion and exudative retinal detachment following a non perforating Yttrium-Aluminium-Garnett (YAG)-laser iridotomy.

DESIGN

Case report.

METHODS

A 53-year-old woman complains of sudden onset of blurred vision in her left eye 15 days after the attempt of YAG-laser peripheral iridotomy. Clinical examination revealed 3+ flare and 1+ cells in the anterior chamber, 2+ vitreous cells, swollen optic nerve, ciliochoroidal effusion, and exudative retinal detachment involving macular area in the left eye. After starting treatment with prednisone 25 mg once daily, choroidal effusion and retinal detachment were managed successfully without any surgical approach.

CONCLUSION

Serous choroidal and exudative retinal detachments are rare complications following YAG-laser procedure. In our case, this clinical presentation occurs after a non perforating iridotomy. In medical practice, exudative retinal detachment should be always considered after YAG-laser iridotomy.

Retinal giant cyst treated by the scleral buckling procedure: A case report

INTRODUCTION

Retinal cysts are rare lesions of the fundus that are essentially fluid-filled cavities located or originating in the retina, with a diameter larger than the normal retinal thickness. To date, there have been few case reports of giant retinal cyst hemorrhage with retinoschisis.

CASE PRESENTATION

A 32-year-old woman with no other medical history complained of decreased vision for 3 days after a severe cough. The best-corrected visual acuity in the right eye was 0.5. A comprehensive ophthalmological examination including slit-lamp fundoscopy, ultrasound scan of the eye, optical coherence tomography scan, and orbital magnetic resonance imaging was performed. Ophthalmological examination revealed grade III anterior chamber blood cells and grade III vitreous hemorrhage in the right eye and a large herpetic cyst on the nasal side of the retina. The cyst projected into the vitreous, with a large amount of hemorrhage vaguely visible within it. The cyst was clearly visible, and a superficial retinal limiting detachment was observed around it. Ultrasound showed a retinal cyst with retinal detachment in the right eye. Laboratory test results were unremarkable. After 3 months of conservative treatment, the patient's intracystic hemorrhage was significantly absorbed, but the size of the cyst cavity did not show any significant change. Scleral buckling with external compression combined with external drainage of the intracystic fluid was performed, the patient's visual acuity was gradually restored to a normal 1.0 after the operation, and the retina appeared flattened. The patient was finally diagnosed with a giant retinal cyst with retinoschisis in the right eye. The presumed cause was heavy coughing leading to rupture and hemorrhage of the retinal cyst, similar to the mechanism of rupture of an arterial dissection. To the best of our knowledge, this case of retinal cyst rupture and hemorrhage caused by heavy coughing with good recovery after external surgical treatment has never been reported before.

CONCLUSIONS

Giant cystic retinal hemorrhage with retinoschisis is very rare. Orbital magnetic resonance imaging and ocular B-scan ultrasound are essential for its diagnosis, and the selection of an appropriate surgical procedure is necessary to maximize the benefit for affected patients.

Outcomes following repair of early-onset versus delayed-onset rhegmatogenous retinal detachments after acute posterior vitreous detachment

AIM

To report anatomical and functional outcomes after surgical repair of acute-onset vs delayed-onset rhegmatogenous retinal detachments (RDs) following acute posterior vitreous detachment (PVD).

METHODS

A retrospective, comparative interventional cohort study where patients presenting to a single-centre retina practice between October 2015 and March 2020 with delayed RDs (diagnosed ≥42 days after initial presentation of acute PVD) were compared with a 2:1 age-matched and gender-matched acute RD cohort (PVD and RD at initial presentation). The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) at 3 months after RD repair.

RESULTS

A total of 210 eyes were analysed-70 in the delayed RD group and 140 in the acute RD group. SSAS was 58/70 (82.9%) for the delayed RD group and 112/140 (80%) for the acute RD group (p=0.71). At the time of RD diagnosis, mean (SD) logarithm of minimum angle of resolution visual acuity (VA) was 0.51 (0.70) (Snellen, 20/65) in the delayed RD group vs 1.04 (0.92) (Snellen, 20/219) in the acute RD group (p<0.001). Mean VA was better at 1 and 3 months post-repair in the delayed RD group (p=0.005 and 0.041, respectively) but similar by 6 months, 12 months and at the final visit post-repair (p=0.48, 0.27, and 0.23, respectively).

CONCLUSIONS

Delayed-onset RDs occurring ≥6 weeks after initial presentation to a retina specialist with an acute PVD generally had better VA at the time of RD diagnosis and faster post-surgical visual recovery compared with acute-onset RDs diagnosed at the initial presentation. No significant difference in anatomic outcomes was seen between the two groups.

Face-down positioning or posturing after pars plana vitrectomy for macula-involving rhegmatogenous retinal detachments

BACKGROUND

A macula-involving rhegmatogenous retinal detachment (RRD) is one of the most common ophthalmic surgical emergencies and causes significant visual morbidity. Pars plana vitrectomy (PPV) with gas tamponade is often performed to repair primary macula-involving RRDs with a high rate of anatomical retinal reattachment. It has been advocated by some ophthalmologists that face-down positioning after PPV and gas tamponade helps reduce postoperative retinal displacement. Retinal displacement can cause metamorphopsia and binocular diplopia.

OBJECTIVES

The primary objective of this review is to determine whether face-down positioning reduces the risk of retinal displacement following PPV and gas tamponade for primary macula-involving RRDs.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (which contains the Cochrane Eyes and Vision Trials Register) (2022, Issue 11), MEDLINE (January 1946 to 28 November 2022), Embase.com (January 1947 to 28 November 2022), PubMed (1948 to 28 November 2022), Latin American and Caribbean Health Sciences Literature database (1982 to 28 November 2022), ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform. We did not use any date or language restrictions in the electronic search. We last searched the electronic databases on 28 November 2022.

SELECTION CRITERIA

We included randomized controlled trials (RCTs) in which face-down positioning was compared with no positioning or another form of positioning following PPV and gas tamponade for primary macula-involving RRDs.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology and assessed the certainty of the body of evidence for the prespecified outcomes using the GRADE approach.

MAIN RESULTS

We identified three RCTs (369 eyes of 368 participants) that met the eligibility criteria. Two RCTs provided data on postoperative retinal displacement, one reported on postoperative distortion and quality of life outcomes, two on postoperative best-corrected visual acuity (BCVA) in logMAR, and two on postoperative ocular adverse events such as outer retinal folds. Study characteristics and risk of bias All the trials involved predominantly male participants (range: 68% to 72%). Only one trial provided race and ethnicity information, was registered on a trial registry, and reported funding sources. Using the RoB 2 tool, we assessed the risk of bias for proportion of eyes with retinal displacement, mean change in visual acuity, objective distortion scores, quality of life assessments, and ocular adverse events, with most domains judged to be at low risk of bias. Findings Immediate face-down positioning may result in a lower proportion of participants with postoperative retinal displacement compared with support-the-break positioning at six months (risk ratio [RR] 0.73, 95% confidence interval [CI] 0.54 to 0.99; 1 RCT; 239 eyes of 239 participants; very low certainty evidence). One study found no evidence of a difference in BCVA at three months when comparing postoperative face-up with face-down positioning with or without perfluorocarbon liquid (mean difference [MD] -0.03, 95% CI -0.09 to 0.02; I2 = 0; 56 eyes of 56 participants; very low certainty evidence). Immediate face-down positioning appears to have little to no effect on postoperative distortion scores at week 26 (MD 1.80, 95% CI -1.92 to 5.52; 1 RCT; 219 eyes of 219 participants; very low certainty evidence) and postoperative quality of life assessment scores at week 26 (MD -1.80, 95% CI -5.52 to 1.92; 1 RCT; 217 eyes of 217 participants; very low certainty evidence). Adverse events One study that enrolled 262 participants with macula-involving RRDs suggested that immediate face-down positioning after PPV and gas tamponade may reduce the ocular adverse event of postoperative outer retinal folds at six months (RR 0.39, 95% CI 0.17 to 0.90; 1 RCT; 262 eyes of 262 participants; very low certainty evidence) and binocular diplopia (RR 0.20, 95% CI 0.04 to 0.90; 1 RCT; 262 eyes of 262 participants; very low certainty evidence) compared with support-the-break positioning. Immediate face-down positioning may increase the ocular adverse event of elevated intraocular pressure compared with support-the-break positioning (RR 1.74, 95% CI 1.11 to 2.73; 1 RCT; 262 eyes of 262 participants; very low certainty evidence). Another study found no evidence of a difference in postoperative outer retinal folds when comparing face-down versus face-up positioning at one and three months (RR 1.00, 95% CI 0.50 to 2.02; RR 1.00, 95% CI 0.28 to 3.61; 1 RCT; 56 eyes of 56 participants; very low certainty evidence). No studies reported non-ocular adverse events.

AUTHORS' CONCLUSIONS

Very low certainty evidence suggests that immediate face-down positioning after PPV and gas tamponade may result in a reduction in postoperative retinal displacement, outer retinal folds, and binocular diplopia, but may increase the chance of postoperative raised intraocular pressure compared with support-the-break positioning at six months. We identified two ongoing trials that compare face-down positioning with face-up positioning following PPV and gas tamponade in participants with primary macula-involving RRDs, whose results may provide relevant evidence for our stated objectives. Future trials should be rigorously designed, and investigators should analyze outcome data appropriately and report adequate information to provide evidence of high certainty. Quality of life and patient preferences should be examined in addition to clinical and adverse event outcomes.

Internal limiting membrane peeling in rhegmatogenous retinal detachment: A meta-analysis

PURPOSE

To determine whether pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for rhegmatogenous retinal detachment (RRD) could get better functional and anatomical outcomes.

METHODS

A comprehensive literature search was performed to find relevant studies. A meta-analysis was conducted by comparing the weighted mean differences (WMD) in the mean change of best corrected visual acuity (BCVA) from baseline and calculating the odd ratios (OR) for rates of epiretinal membrane (ERM) formation and recurrence of retinal detachment (RD).

RESULTS

Fourteen studies were selected, including 2259 eyes (825 eyes in the ILM peeling group and 1434 eyes in the non-ILM peeling group). There was no significant difference in terms of mean change in BCVA from baseline and the rate of RD recurrence (WMD = 0.02, 95% CI, -0.20 to 0.24, P = 0.86, and OR = 0.55, 95% CI, 0.24 to 1.26, P = 0.16), but ILM peeling was associated with a significantly lower frequency of postoperative ERM formation (OR = 0.13, 95% CI, 0.06 to 0.26, P<0.00001). Similar results were obtained in a sub-analysis based on macula-off RRD.

CONCLUSION

ILM peeling results in similar BCVA, with same rate of RD recurrence, but lower rate of postoperative ERM development. ILM peeling could be considered in selected cases with risk factors that are likely to develop an ERM.

Retinal detachment

Retinal detachment (RD) occurs when the neurosensory retina, the neurovascular tissue responsible for phototransduction, is separated from the underlying retinal pigment epithelium (RPE). Given the importance of the RPE for optimal retinal function, RD invariably leads to decreased vision. There are three main types of RD: rhegmatogenous, tractional and exudative (also termed serous) RD. In rhegmatogenous RD, one or more retinal breaks enable vitreous fluid to enter the subretinal space and separate the neurosensory retina from the RPE. In tractional RD, preretinal, intraretinal or subretinal membranes contract and exert tangential forces and elevate the retina from the underlying RPE. Finally, in exudative RD, an underlying inflammatory condition, vascular abnormality or the presence of a tumour causes exudative fluid to accumulate in the subretinal space, exceeding the osmotic pump function of the RPE. The surgical management of RD usually involves pars plana vitrectomy, scleral buckling or pneumatic retinopexy. The approach taken often depends on patient characteristics as well as on practitioner experience and clinical judgement. Advances in surgical technology and continued innovation have improved outcomes for many patients. However, even if retinal re-attachment is achieved, some patients still experience decreased vision or other visual symptoms, such as metamorphopsia, that diminish their quality of life. Continued research in the areas of neuroprotection and retinal biology as well as continued surgical innovation are necessary to enhance therapeutic options and outcomes for these patients.

[Emphasizing the timing and procedure selection for vitrectomy in pathological myopic traction maculopathy]

Myopic maculopathy is the primary cause of irreversible visual impairment in patients with pathologic myopia, and myopic traction maculopathy often requires vitrectomy for treatment. Myopic traction maculopathy encompasses epiretinal membrane, foveoschisis, macular hole, and macular hole-related retinal detachment. It is recommended to perform vitrectomy combined with inner limiting membrane peeling for Type II epiretinal membrane, foveal-sparing inner limiting membrane peeling for foveoschisis, inverted inner limiting membrane flap technique for macular hole, and vitrectomy combined with macular buckle for refractory macular hole-related retinal detachment. Myopic traction maculopathy is a chronically progressive condition, and surgeons need to accurately determine the timing of surgery and choose appropriate procedures to maximize the benefits for patients.

THE LONG-TERM RECOVERY OF VISION IN PSEUDOPHAKIC MACULA-OFF RHEGMATOGENOUS RETINAL DETACHMENTS

PURPOSE

To assess the long-term visual recovery in uncomplicated macula-off pseudophakic rhegmatogenous retinal detachment treated with pars plana vitrectomy and gas tamponade in the absence of other visual comorbidities.

METHODS

Single-center retrospective longitudinal study on eyes with macula-off pseudophakic rhegmatogenous retinal detachment successfully treated with pars plana vitrectomy between 2011 and 2020 and with at least 2 follow-ups (FU), first gas-free FU (first-FU) and a final-FU, were included. Patients with subsequent ocular surgery or comorbidities affecting best-corrected visual acuity were excluded. The duration between operation date and final-FU was calculated (total days FU) and split into total days quintiles-1: ≤57, 2: >57 and ≤77, 3: >77 and ≤152, 4: >152 and ≤508, and 5: >508 days. Multivariable regression was performed with logMAR gain between the first and the final-FU as the dependent variable.

RESULTS

In 209 eyes, the authors report association with increase of logMAR gain between the first and the final-FU, with reducing clock hours of pseudophakic rhegmatogenous retinal detachment ( P = 0.041) and relative to the total days Quintile 1. Mean (SD) logMAR gain between the first and the final-FU was 0.02 (0.07) in the first quintile, increasing to 0.14 (0.13) ( P < 0.001) by the fifth quintile on multivariable regression. For patients not achieving 0.30 logMAR at the first-FU, this was attained at the final-FU with a sensitivity of 51.9% and specificity of 95.5% at a cut off ≤0.58 logMAR at the first-FU (area under the curve 0.756 [95% confidence interval 0.664-0.848], P < 0.001).

CONCLUSION

The authors report a significant time-dependent visual improvement after uncomplicated pars plana vitrectomy with gas tamponade for macula-off pseudophakic rhegmatogenous retinal detachment without visual confounders and provide important quantitative data for counselling patients with macula-off repair.

Aqueous misdirection syndrome post silicone oil removal in a vitrectomized eye - a case report

PUROPSE

Aqueous misdirection syndrome (AMS) is an aggressive post-operative glaucoma unresponsive to conventional measures with grave outcomes. In this report, we describe a rare case of AMS following silicon oil removal in a vitrectomized eye.

METHODS

A diabetic patient with tractional retinal detachment underwent pars plana vitrectomy with silicon oil injection. Following retinal reattachment, silicon oil removal was performed at three months. Post oil removal she developed increased intraocular pressure with shallowing of both the peripheral and central anterior chamber suggestive of AMS.

RESULTS

Initial medical management with anti-glaucoma medications and cycloplegics was not beneficial. A pars plana lensectomy with complete anterior hyaloidectomy along with a surgical peripheral iridectomy helped relieve the aqueous misdirection.

CONCLUSION

AMS can rarely occur following vitrectomy and is likely secondary to intact anterior hyaloid. Lensectomy along with zonulo-hyaloido-iridectomy is essential. This report highlights the occurrence of this rare complication and its effective management.

Long-term complications according to silicone oil type. A single center cohort study

PURPOSE

To study the incidence of macular edema (ME), ocular hypertension (OHT), emulsification and migration to the anterior chamber (AC) of silicone oil (SO) in patients after complex retina surgery, stratified by SO type.

METHODS

Retrospective, cohort study. Patients who underwent retina surgery with SO injection and extraction in our center were included. We compared the complication rates of ME, OHT, emulsification and migration to the AS according to SO type (1300cSt, 5700cSt and heavy SO). Data on age, sex, emulsification time, duration of the tamponade, previous retina surgeries and diagnosis were also gathered and included in a multivariate analysis.

RESULTS

We included 163 patients (mean age of 64.8 years; mean duration of the tamponade: 11 months). Rates of emulsification, ME, OHT and SO migration to the AC were similar in all groups (p = 0.998, 0.668, 0.915 and 0.360). ME was the most frequent complication (33.3-47.8%), which resolved after SO extraction in 77.6% of cases. The majority of cases with OHT persisted (61.7%). Emulsification was related to younger age (OR 0.94) and longer duration of the tamponade (OR 1.04). The odds of SO migration to the AC increased with emulsification (OR 2.78), recurrent retinal detachment (OR 0.99) and aphakia (OR 4.05).

CONCLUSIONS

We propose SO extraction as the preferred treatment for ME during SO tamponade. SO extraction should be performed sooner in younger patients to avoid emulsification. In selected patients, we suggest a longer duration of the tamponade up to 11 months with a reasonable safety profile, regardless of the SO type.

Quality of Life after Pars Plana Vitrectomy, Scleral Buckle, or Pneumatic Retinopexy for Rhegmatogenous Retinal Detachment: A Meta-Analysis

PURPOSE

Comparisons of the surgical and anatomic results of rhegmatogenous retinal detachment surgery have been investigated previously. A systematic evaluation of the available evidence comparing quality of life outcomes of either pars plana vitrectomy, scleral buckling, or pneumatic retinopexy has not been evaluated to date. This article analyzes whether pars plana vitrectomy, scleral buckling, or pneumatic retinopexy for the treatment of rhegmatogenous retinal detachment results in differing quality of life outcomes.

METHODS

In February of 2022, a comprehensive search of MEDLINE, EMBASE, CINHAL, and Cochrane Library was conducted for studies on patients treated surgically for rhegmatogenous retinal detachment and included follow-up measurements of quality of life outcomes. Meta-analysis was completed using STATA v. 14.0. The main outcomes of interest were the mean vision-related quality of life score (VRQOL) and SD of VRQOL of each type of surgical procedure.

RESULTS

In this systematic review of 13 distinct trials including follow-up of patient quality of life after rhegmatogenous retinal detachment surgery (n = 1063), a better correlation was found between higher quality of life outcomes with scleral buckling than with pars plana vitrectomy (SMD = 0.62, CI: [0.31, 0.93]). There was also no signficant difference in quality of life outcomes between pneumatic retinopexy and pars plana vitrectomy (SMD = 0.08, CI: [-0.07, 0.22]).

CONCLUSIONS

Scleral buckling results in better quality of life outcomes for patients when compared to pars plana vitrectomy. Pneumatic retinopexy did not show a difference in quality of life outcomes compared to pars plana vitrectomy.

Brolucizumab for recalcitrant macular neovascularization in age-related macular degeneration with pigment epithelial detachment

PURPOSE

To analyze anatomic and functional response to intravitreal brolucizumab in age-related macular degeneration recalcitrant to previous intravitreal anti-VEGF therapies.

METHODS

In this monocentric, one arm, retrospective study, eyes affected by neovascular age-related macular degeneration (nAMD) resistant to other intravitreally injected anti-vascular endothelial growth factor inhibitors were switched to intravitreal brolucizumab. All patients underwent ophthalmological examinations at baseline and in regular follow-up intervals. Best registered visual acuity (BRVA), Goldmann tonometry, intraocular pressure (IOP), central retinal thickness (CRT) and pigment epithelial detachment (PED) characteristics were analyzed at initiation of anti-VEGF treatment, at treatment switch, and at the end of brolucizumab loading phase.

RESULTS

The study included 20 eyes of 18 consecutively treated patients (age: 77 ± 6 years). All eyes had macular neovascularization with PED. Previous treatments included intravitreal aflibercept, bevacizumab, and ranibizumab and had not resulted in a significant improvement in BRVA (0.5 ± 0.5 logMAR vs 0.5 ± 0.6 logMAR) or mean CRT (320 ± 60 µm vs 313 ± 83 µm) up to treatment switch to brolucizumab. At the end of the brolucizumab loading phase, there was significant improvement for both BRVA (0.3 ± 0.2 logMAR, P < 0.05) and CRT (264 ± 55 µm, P < 0.05). Under previous anti-VEGF therapy, there was a significant increase/deterioration in both PED area (2.68 mm2 to 5.18 mm2, P < 0.05) and PED volume (0.39 mm3 to 1.07 mm3, P < 0.05); however, both parameters improved after switching to brolucizumab (3.81 mm2 and 0.37 mm3, P < 0.05).

CONCLUSION

Our results suggest a favourable anatomical and visual response after treatment switch to brolucizumab in patients with nAMD refractory to previous anti-VEGF agents.

PURPOSEFUL GAS-INDUCED RESORPTION OF SUBMACULAR FLUID IN MACULA-OFF RETINAL DETACHMENTS (PERSIMMON STUDY)

PURPOSE

To examine the visual outcomes in patients with macula-off rhegmatogenous retinal detachments with intentional submacular fluid retention after pars plana vitrectomy (PPV) or PPV/scleral buckle surgery (PPV/SB).

METHODS

Patients with macula-off retinal detachments were included if they had a PPV or PPV/SB without drainage retinotomy or perfluorocarbon liquid to flatten the retina.

RESULTS

The mean age of the patients was 65.0 years. The mean presenting vision was 20.0 Early Treatment Diabetic Retinopathy Study (ETDRS) letters. Six months after repair, the vision improved to 62.9; 75.4% of patients had 20/40 or better at best achieved visual acuity. Pseudophakic eyes had better vision compared with phakic eyes ( P = 0.049). Patients younger than 80 years had better best achieved vision ( P = 0.0118) compared with patients 80 years or older. Patients with initial vision better than or equal to 20/100 had better best achieved vision ( P = 0.016) compared with those with initial vision worse than 20/100.

CONCLUSION

Leaving submacular fluid after macula-off retinal detachments surgery was not detrimental for visual outcomes or anatomic success for retinal detachments repair and may lead to better visual outcomes for patients, specifically for those patients younger than 80 years, who are pseudophakic, and have presenting vision 20/100 or better.

The efficacy of different anti-vascular endothelial growth factor agents, and dexamethasone implant therapy in patients with serous retinal detachment caused by Irvine-Gass syndrome

PURPOSE

The aim of this study is to compare the efficacy of intravitreal aflibercept (IVA), bevacizumab (IVB), ranibizumab (IVR), and dexamethasone implant (IVDI) in the treatment of serous retinal detachment (SRD) caused by Irvine-Gass syndrome (IGS).

DESIGN

Retrospective cohort, comparative study.

METHODS AND MATERIALS

The medical records of 128 eyes with no previous history of intravitreal agents in 128 IGS patients with SRD that received IVA, IVB, IVR, and IVDI monotherapy were retrospectively reviewed. The patients were divided into 4 groups, according to treatment. Patients with recurrence and/or were unresponsive following a course of topical steroids and non-steroidal anti-inflammatory drugs (NSAIDs) were included in the study. Best corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal choroidal thickness (SFCT), and SRD were compared between the 4 treatment groups at baseline, at follow-up months 1, 3, 6, and 12, and at the final follow-up visit.

RESULTS

Serous retinal detachment completely resolved in 74%, 45.7%, 66.4%, and 40.8% of the eyes at month 1 (P = 0.042), 87%, 50.9%, 75.8%, and 80.9% at month 3 (p = 0.031), 88.9%, 50.4%, 75.7%, 80.2% at month 6 (p = 0.028), 81.7%, 72.8%, 68.7%, 80.1% at month 12 (p = 0.580), and 100%, 66.4%, 87.9%, 93.2% (p = 0.478) at final follow-up visit in the IVA, IVB, IVR, and IVDI groups, respectively. BCVA was significantly better in the IVA group at all follow-up time points (month 1: p < 0.001; month 3: p < 0.001; month 6: p = 0.002; month 12: p = 0.009, final follow-up visit: p < 0.001). CMT was significantly lower in the IVA group at months 3 (p = 0.008), 6 (p = 0.011), and 12 (p = 0.010), and at the final follow-up visit (p < 0.001). Recurrence was observed after a longer period of time and fewer injections were needed in the IVDI and IVA groups (p < 0.05). Resolution of CME was most rapid in the IVA group (p = 0.032).

CONCLUSION

All intravitreal agents were effective in terms of visual results in the SRD patients; however, eyes treated with IVA and IVDI required fewer injections, as compared to the eyes treated with IVB and IVR. Furthermore, SRD entirely resolved in all eyes in the IVA group at the final follow-up visit.

Posterior vitreous detachment and retinal tear - a prospective study of community referrals

BACKGROUND

Retinal tears (RT) from posterior vitreous detachment (PVD) are an important and treatable cause of rhegmatogenous retinal detachment (RRD). Better understanding of the risk of RT from PVD will help plan urgent eye care.

METHODS

Prospective observational case series over two years. Patients presenting to their optometrist, family doctor or emergency department with flashes and floaters were directed to a research clinic. History and examination, including slit-lamp biomicroscopy (SLB) and indentation indirect ophthalmoscopy (IIO), were performed by a single investigator, with two month follow-up for patients with confirmed PVD. Main outcome measures were incidence of PVD, RT, and RRD.

RESULTS

1010 patients were recruited. 896 (89%) patients had PVD at first assessment, of which 89 (8.8% of total cohort, 9.9% of PVD eyes) had RT and 8 had RRD. 21 (3%) of the remaining PVD patients developed RT in the subsequent two months and a further 9 (11%) patients with RT at initial assessment developed further tears by two months. 7 (0.7%) had asymptomatic RT in the fellow eye. 15% of RT were only visible on IIO and not SLB. Weiss ring was absent in 32% of eyes with RT. Patients with RT or RRD were more likely than 'PVD-only' eyes to have blurred or missing vision (p < 0.001), have higher rate of blue-green cataracts (p < 0.001), and longer axial lengths (p < 0.05).

CONCLUSIONS AND RELEVANCE

This large, prospective study demonstrates a 9.9% rate of RT or RRD at the time of PVD, and emphasises the importance of IIO examination.

RHEGMATOGENOUS RETINAL DETACHMENT WITH CONCURRENT CHOROIDAL DETACHMENT AND MACULAR HOLE FORMATION AFTER UNCOMPLICATED CATARACT EXTRACTION AND INTRAOCULAR LENS IMPLANTATION: A CASE REPORT AND REVIEW OF LITERATURE

PURPOSE

To describe a case of concurrent rhegmatogenous retinal detachment, choroidal detachment, and macular hole (RRD-CD-MH) formation in a patient after uncomplicated cataract extraction and intraocular lens implantation (CEIOL). In addition, we summarize the previously reported cases of RRD-CD-MH in the literature.

METHODS

Interventional case report and literature review.

RESULTS

A 71-year-old white man without relevant medical or ocular history underwent an uncomplicated CEIOL. He presented with counting fingers vision and intraocular pressure of 5 mmHg after 3 weeks. On dilated fundus examination, multiple superior tears and total RRD with a serous CD was evident. Intraoperatively, a full-thickness MH was identified. The patient underwent routine RRD and MH repair, with instillation of 1,000 centistoke silicone oil (SiO). The retina successfully re-attached, the CD resolved, and the intraocular pressure normalized; however, the MH did not initially close. The SiO was removed approximately 4 months later and, while the MH remained open, the patient's vision improved to 20/80. Approximately three years after the surgical repair, the MH closed spontaneously, and the vision remained at 20/80.

CONCLUSION

Our patient developed an RRD-CD-MH after uncomplicated CEIOL. The MH displayed delayed closure. The vision improved after surgical repair, and remained stable in the long term.

Retinal Vasculitis as an Ocular Manifestation in Atopic Dermatitis-Associated Retinal Detachment: A Case Report

Atopic dermatitis is usually associated with various ocular complications. We report a 21-year-old Chinese male who presented to our ophthalmology clinic with bilateral retinal detachment and cataracts. The patient had a clear medical history of atopic dermatitis, which had been diagnosed eight years earlier and had been treated with loratadine and pimecrolimus. Cataract surgery was performed in both eyes, combined with scleral buckling in the right eye and pars plana vitrectomy in the left eye. During postoperative follow-up, fundus fluorescein angiography indicated retinal vasculitis in both eyes and macular edema in the left eye, which coincided with an exacerbation of atopic dermatitis. Macular edema improved after four months of regular dupilumab treatment in the dermatology department. The ocular condition remained stable three years postoperatively.

Macular hole following scleral buckling for rhegmatogenous retinal detachment: a case series

BACKGROUND

Macular hole (MH) development following scleral buckling (SB) surgery for rhegmatogenous retinal detachment (RRD) repair is rare. This study presents both full-thickness MH (FTMH) and lamellar MH (LMH) cases following SB for the treatment of RRD.

METHODS

Clinical records of patients undergoing SB surgery for treatment of RRD at the Xi'an People's Hospital (Xi'an Fourth Hospital) from January 2016 to December 2021 were reviewed, and cases with postoperative MH were selected. Clinical features and follow-up data were summarised, and possible causes were analysed.

RESULTS

Among 483 identified cases (483 eyes), four eyes (three male patients, one female patient) had postoperative MH, with prevalence, mean age, and mean axial length of 0.83%, 43.5 ± 10.66 years, and 29.13 ± 3.80 mm, respectively. All patients did not undergo subretinal fluid (SRF) drainage. The mean time for detecting MH was 26 ± 15.5 days postoperatively. Macula-off RRD with high myopia and FTMH combined with retinal re-detachment were diagnosed in three patients. One patient had macula-on RRD with outer LMH. The average follow-up duration was 7.25 ± 1.5 months. The FTMH closed successfully after reoperation, while the outer LMH closed without intervention. Visual acuity insignificantly improved or slightly decreased in all patients.

CONCLUSIONS

Patients with high myopia combined with macula-off RRD might be more susceptible to FTMH, causing MH related retinal detachment. Additionally, LMH following SB was noted in patients with macula-on RRD. Therefore, we should raise awareness of MH following SB for RRD repair.

INCIDENCE AND RISK FACTORS FOR EXUDATIVE RETINAL DETACHMENT FOLLOWING LASER PHOTOCOAGULATION FOR RETINOPATHY OF PREMATURITY

PURPOSE

Exudative retinal detachment (ERD) may result from laser photocoagulation for retinopathy of prematurity. Although risk factors have been hypothesized from case reports, comparative studies have not been reported. We sought to evaluate risk factors for ERD following laser, comparing affected and unaffected infants.

METHODS

Retrospective cohort study of infants undergoing retinopathy of prematurity laser at the Children's Hospital of Philadelphia over 6 years. All received near-confluent laser of avascular retina. Demographic, medical, and procedural risk factors for ERD were evaluated in univariate analysis because of the rarity of ERD.

RESULTS

Among 149 lasered infants, 6 infants (4%, 95% confidence interval [CI] 1.5%-8.6%) developed ERD. Race was a significant risk factor ( P = 0.01). Among 71 African American or Hispanic infants, 6 (8.5%, 95% CI 3.2%-17.5%) developed ERD. Among 78 non-African American or Hispanic infants, 0 (0%, 95% CI 0%-4.6%) developed ERD. There were no significant differences in the other studied factors.

CONCLUSION

Exudative retinal detachment was uncommon (4%) following retinopathy of prematurity laser. Despite so few cases, darker pigmented race with likely increased pigmented fundi was significantly associated with an increased ERD risk. Further study may reveal whether increased choroidal pigment causes greater laser tissue damage or makes it difficult to discern the ora, resulting in inadvertent lasering of the ciliary body, leading to ERD.

Prevalence of vitreoschisis-induced vitreous cortex remnants over the peripheral retinal surface in eyes undergoing vitrectomy for primary rhegmatogenous retinal detachment

PURPOSE

Unremoved vitreoschisis-induced vitreous cortex remnants over the peripheral retinal surface posterior to the vitreous base (pVCR) may increase the risk of surgical failure after primary rhegmatogenous retinal detachment (RRD) repair. The purpose of this study was to validate our previous findings on pVCR prevalence during vitrectomy for RRD and to examine their association with proliferative vitreoretinopathy (PVR) and surgical failure.

METHODS

Prospective observational multisurgeon study of 100 eyes of 100 consecutive patients who underwent vitrectomy for RRD by one of four vitreoretinal surgeons. Collected data included detected pVCR and known PVR risk factors. Pooled analysis with our previous retrospective study (251 eyes of 251 patients) was also performed.

RESULTS

Initial PVR (≥C) was present and removed in 6/100 (6%) patients, pVCR were detected in 36/100 (36%) patients, pVCR were removed in 30/36 (83%) patients with pVCR, and 4/36 (11%) patients with pVCR were high myopes (≤-6D). Six per cent (6/100) developed a retinal redetachment, of which 3/6 (50%) had initial PVR (≥C). Surgical failure rates in eyes with and without pVCR were 17% (6/36) and 0% (0/64), respectively. In eyes with pVCR and surgical failure, pVCR were not or not completely removed during the first surgery. Overall analysis showed that pVCR were statistically significantly associated with PVR.

CONCLUSIONS

This study confirms our previous findings: a pVCR prevalence of around 35% and an association between pVCR, PVR formation and surgical failure in patients undergoing vitrectomy for RRD. More research is needed to determine which patients would benefit most from pVCR removal.

Rhegmatogenous retinal detachment in choroidal melanoma: clinical features and surgical outcomes

PURPOSE

To describe the clinical features, prognostic factors, safety and rate of success of surgery and visual outcomes in patients with rhegmatogenous retinal detachment (RRD) and choroidal melanoma (CM).

METHODS

A retrospective, observational case-series of 21 patients with rhegmatogenous retinal detachment or combined tractional-rhegmatogenous retinal detachment in patients with choroidal melanoma over a period of 20 years.

RESULTS

Nineteen patients were included in the final analysis. The mean elevation of CM was 4.0 mm and the mean largest diameter was 11.0 mm. RRD occurred after the CM treatment in 14 eyes at a mean interval of 44.2 months. The RRD was macula-on RRD in 6 eyes, there was posterior vitreous detachment (PVD) in 15 and PVR in 7 eyes. BCVA at presentation was 0.71 logMAR and final was 1.5 logMAR (p = 0.01). The primary surgical success rate was 59%. No intraocular or extraocular tumour dissemination occurred. Mean follow-up was 66 months.

CONCLUSION

RRD in patients with CM is uncommon but requires multidisciplinary management. Anatomical results are favourable but visual outcomes are poor due to a combination of factors related to melanoma treatment, macular retinal detachment and PVR. Vitrectomy as a surgical intervention for RRD in treated CM appears to be safe in terms tumour dissemination.

Incidental Finding of Suprachoroidal Space's Silicone Oil Migration: A Tumor-Mimicking Lesion and Its Clinical Management

The migration of silicone oil into the suprachoroidal region is a rare complication of vitrectomy. A 70-year-old man was admitted to our ocular oncology unit with a choroidal elevation in the nasal area, as well as signs of pars plana vitrectomy surgery performed about 5 years ago for retinal detachment. The patient underwent ocular ultrasound, visual field test, fluorangiography, and magnetic resonance imaging, which led to the diagnosis of silicone oil migration in the suprachoroidal space. Silicone oil may move into the suprachoroidal area, mimicking choroidal neoformation. It is important to have a comprehensive diagnosis and then set up the appropriate treatment.

Intra-Anterior Chamber Injection of Ranibizumab in Advanced Pediatric Vitreoretinal Diseases

Importance

Anti-vascular endothelial growth factor (VEGF) treatment through intravitreal or subretinal administrations has been proven effective for VEGF-driven pediatric vitreoretinal diseases but are not feasible for advanced cases, such as shallow traction retinal detachments or peripheral circumferential retinal detachments which adhere to the lens. Intra-anterior chamber injection (IAcI) of anti-VEGF may be a viable alternative in such cases but needs evaluation.

Objective

To investigate the effects and safety of IAcI of anti-VEGF to treat VEGF-driven pediatric vitreoretinal diseases.

Design, Setting, and Participants

This was a retrospective observational case series study conducted at Xinhua Hospital, affiliated with Shanghai Jiao Tong University School of Medicine in China. The study included 14 eyes of 13 children diagnosed with vitreoretinal disease exhibiting elevated vascular activity between January and August 2023.

Intervention

IAcI with ranibizumab.

Main Outcomes and Measures

Retinal vascular abnormalities, vitreous hemorrhage resolution, and complications 1 month and 3 months after injection.

Results

Of 13 patients included in this study, 12 were male. The mean age was 4.6 years (range, 1 month to 9 years). Six patients were diagnosed with familial exudative vitreoretinopathy, 4 with morning glory syndrome, 1 with retinopathy of prematurity, and 2 with chronic retinal detachments of unknown causes. At 1-month postoperative follow-up, vascular activity had decreased in 14 of 14 eyes. At 3-month follow-up, vascular activity had resolved in 7 of 14 eyes, persisted in 6 of 14 eyes, and reactivated in 1 of 14 eyes. On final observation, no complications were reported.

Conclusions and Relevance

These findings support the possibility of treatment using IAcI with ranibizumab to decrease retinal vascular abnormalities in familial exudative vitreoretinopathy or retinopathy of prematurity or related conditions, but further studies are needed to understand more precise benefits and risks. This approach might be considered in cases where intravitreal or subretinal injection are not feasible, recognizing the limitations of these findings and that longer-term outcomes still need to be monitored.

Evaluation of epiretinal membrane formation after scleral buckling for treating rhegmatogenous retinal detachment: En face optical coherence tomography image-based study

PURPOSE

To assess epiretinal membrane (ERM) formation, severity, and the associated risk factors after scleral buckling using en face optical coherence tomography (OCT) images.

METHODS

Medical records of 61 consecutive patients (66 eyes) with rhegmatogenous retinal detachment who underwent scleral buckling were retrospectively reviewed. Posterior vitreous detachment (PVD) was determined based on B-scan OCT images. En face OCT images were used to visualize the ERM and retinal folds. ERM formation was identified by comparing en face images pre- and post-surgery. The maximum depth of the retinal folds (MDRF) was measured using en face imaging to objectively assess traction strength.

RESULTS

ERM formation occurred in 15 (22.7%) eyes at the final visit; the foveal pit was preserved in all cases. Parafoveal retinal folds were present in 5 (7.6%) eyes, with a mean MDRF of 21.8 ± 12.6 µm. No significant difference was observed in best-corrected visual acuity (logarithm of the minimal angle of resolution) between the ERM formation (-0.019 ± 0.128) and non-ERM formation (-0.001 ± 0.213) groups at the final visit (P = 0.593; Mann-Whitney U test). Multivariate logistic regression analysis revealed that older age and the presence of PVD were significant risk factors for ERM formation (odds ratio 1.07, 95% confidence interval 1.01-1.14, P = 0.032; odds ratio 5.26, 95% confidence interval 1.06-26.10, P = 0.042; respectively).

CONCLUSION

ERM occurred in 22.7% of cases but was mild and did not affect visual acuity. Older age and the presence of PVD are risk factors for ERM formation.

Early-Onset Myopia and Retinal Detachment without Typical Microcoria or Severe Proteinuria due to a Novel LAMB2 Variant

PURPOSE

To describe the ocular and renal features, as well as outcomes of retinal detachment repair, in patients with a novel, homozygous laminin β-2 (LAMB2) pathogenic variant.

DESIGN

Single-center retrospective chart review of patients with a homozygous variant, c.619T>C p.(Ser207Pro), in the LAMB2 gene.

SUBJECTS

Eleven patients (22 eyes) from 4 families.

METHODS

Demographic data and ocular findings were recorded. Patients were recalled for a detailed renal evaluation.

MAIN OUTCOME MEASURES

Ocular features, renal features, and outcomes of retinal detachment repair.

RESULTS

The mean age at presentation was 6.0 (range, 1-26) years. None of the study eyes had microcoria, and none of the patients had nephrotic-range proteinuria. The mean refraction and axial length were -7.9 diopters (range, -4.0 to -12.0 diopters) and 25.3 (range, 22.7-27.7) mm, respectively. Eleven eyes (50%) had cataract at presentation. Fifteen eyes had a clear view to the fundus and all showed tessellated myopic fundus, avascular peripheral retina evident clinically or on fluorescein angiography, and rudimentary fovea. Optic disc pallor was observed in 10 eyes (66.7%). Straightened retinal vessels, abnormal vascular emanation (situs inversus) from the optic disc, supernumerary vascular branching at the optic disc, and vascular tortuosity were observed in 10 (66.7%), 2 (13.4%), 2 (13.4%), and 2 (13.4%) eyes, respectively. Discrete areas of punched-out chorioretinal atrophy were observed in 4 (26.7%) eyes. Spectral-domain OCT showed retinal and choroidal thinning in 13 eyes (86.7%), retinoschisis temporal to the fovea in 2 eyes (13.4%), and rudimentary fovea in 15 eyes (100%). Among the 22 eyes, 14 eyes (63.6%) developed rhegmatogenous retinal detachment (RRD), mostly during childhood, of which 5 patients had bilateral RRD. Eight eyes were operated on and 6 (75%) achieved retinal reattachment at the last follow-up. The mean preoperative visual acuity was 20/300 and the mean postoperative visual acuity at the last follow-up was 20/400.

CONCLUSIONS

This study describes a distinct phenotype of LAMB2-related disease with a novel, homozygous LAMB2 variant, and further expands the spectrum of ophthalmic and renal features, and the molecular genetic basis, of LAMB2-related disease. Because the typical microcoria and nephrotic-range proteinuria might be absent, the retinal features can guide the diagnosis.

Use of 30 gauge needle to prevent hypotony during silicone oil removal

Silicone oil (SO) is used as an intraocular tamponade after complex vitreoretinal surgeries because of its properties such as transparency, inertness, high surface tension, and interfacial tension with water. The only disadvantage of SO tamponade is the need for a second surgery for its removal. However, there is a risk of ocular hypotony soon after the removal of the infusion cannula, especially in retinal vascular conditions, such as diabetic retinopathy. We hereby present a silicone oil removal (SOR) technique using a 30 G needle that prevents intraocular hypotony during SOR.

Bilateral Combined Rhegmatogenous and Tractional Retinal Detachments Due to Persistent High-Titer Syphilis

A 23-year-old man developed bilateral rhegmatogenous retinal detachments secondary to high-titer ocular syphilis. The patient's titer increased four-fold after completing a 14-day course of intravenous penicillin (IVP). He underwent bilateral pars plana vitrectomy with silicone oil fill in both eyes. In this article, the authors propose an updated treatment method for patients with advanced ocular syphilis that includes oral doxycycline for 30 days following 14 days of IVP to optimally minimize the patient's infectious burden. Following surgery and this new treatment regime, this patient's best-corrected visual acuity 10 weeks postoperatively measured 20/50 in the right eye and 20/30 in the left eye. This case highlights a rare but devastating complication of ocular syphilis. We suggest the addition of oral doxycycline to IVP for patients with syphilis titers ≥ 1:256, HIV co-infection, and presence of posterior retinitis.

MANAGEMENT OF RETINAL DETACHMENT ASSOCIATED WITH MORNING GLORY SYNDROME USING THE HUMAN AMNIOTIC MEMBRANE

PURPOSE

This case report describes an innovative procedure for addressing retinal detachment in patients with morning glory syndrome.

METHODS

An 18-year-old woman with unilateral morning glory syndrome complicated by macula-off retinal detachment without any visible peripheral retinal breaks underwent three corrective surgeries. In the first surgery, a 25-gauge pars plana vitrectomy with a 3-mm human amniotic membrane patch positioned on the optic disc and gas endotamponade was performed. When the gas reabsorbed, inferior retinal detachment recurred, and a second vitrectomy with silicone oil endotamponade was conducted. At three months, the retina was still attached under the silicone oil, so the oil was removed. At the second follow-up, retinal detachment had recurred, and a third vitrectomy with a larger amniotic patch and silicone oil endotamponade was performed.

RESULTS

Three months following the last surgery, the subretinal fluid had totally reabsorbed, and the retina was completely attached. The best-corrected visual acuity was 20/100.

CONCLUSION

To the best of our knowledge, the first description of a human amniotic patch associated with vitrectomy in morning glory syndrome complicated with retinal detachment is described. Using human amniotic membranes, positioned onto the optic nerve, and silicone oil endotamponade could be useful for morning glory syndrome complicated by retinal detachment.
