Abstract
OBJECTIVE To determine the preference for dacryocystorhinostomy (DCR), patient selection criteria for endoscopic DCR, endoscopic DCR technique, and barriers to adoption of endoscopic DCR. METHOD Cross-sectional study conducted from May-December 2021. A survey was sent to oculoplastic surgeons. Questions on demographic characteristics, type of clinical practice, technique preferences, barriers and facilitators to adoption of endoscopic DCR were included. RESULTS 245 participants completed the survey. Most respondents were located at an urban site (84%), were in private practice (66%), and had been in practice for more than 10 years (58.9%). Sixty one percent perform external DCR as the first line procedure for treating primary nasolacrimal duct obstruction. The most common factor influencing the surgeon's decision to perform endoscopic DCR was the patient's request (37%) followed by endonasal exam (32%). The most common barrier for not performing endoscopic DCR was the lack of experience and lack of training during fellowship (42%). The most worrisome complication for most respondents was failure of the procedure (48%), followed by bleeding (30.3%). Eighty one percent believe surgical mentorship and supervision during initial cases would facilitate endoscopic DCR learning. CONCLUSIONS External Dacryocystorhinostomy is the preferred technique for treating primary acquired nasolacrimal duct obstruction. Learning endoscopic DCR early during fellowship training and high surgical volume to improve the learning curve dramatically impacts the adoption of the procedure.

Recurrent and recalcitrant upper lid cicatricial entropion following combined chemotherapy: Clinical and pathology correlation. Saudi J Ophthalmol 2022; 35:347-349. [PMID: 35814986 PMCID: PMC9266477 DOI: 10.4103/1319-4534.347308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Revised: 06/26/2020] [Accepted: 12/09/2020] [Indexed: 11/04/2022] Open
Abstract
We report a case of recalcitrant bilateral upper eyelid cicatricial entropion associated with distichiasis/trichiasis which followed an adjuvant systemic chemotherapy. The chemotherapy, administered for treatment of breast cancer, consisted of docetaxel, carboplatin, and herceptin. Shortly following the combined chemotherapy treatment, epiphora and eyelash abnormalities commenced. The patient presented with a swollen eyelid margin and tarsal conjunctival inflammation associated with cicatricial entropion and diffused distichiasis/trichiasis affecting the upper lids, with greater severity observed in the medial portion. Despite manual epilation and multiple argon laser sessions, no improvement was noted. Surgical treatment was performed using a lid split, distichiasis excision of the right upper lid, and homolateral tarsoconjunctival graft. The biopsy examination showed chronic inflammation, dermal fibrosis with squamous metaplasia process, and an abnormal epithelial differentiation. After 6 months, entropion recurred. Tarsal marginal rotation associated with posterior lamella advancement was performed. However, cicatricial entropion and distichiasis/trichiasis recurred. The patient was prescribed bandage contact lenses and topical lubrication to relieve symptoms.

Abstract
PURPOSE To describe the characteristics and recurrence rates of primary periocular squamous cell carcinoma (SCC) in Spain. METHODS This retrospective study investigates the characteristics of primary periocular SCC at two tertiary centers in Spain from 2000 to 2020. Data were collected on demographics, skin phenotype, location, clinical and histological diagnosis, the commitment of surgical margins, recurrence, and risk factors. Multivariate analysis and risk factors were used to investigate recurrence rates, considering p < 0.05 as statistically significant. RESULTS Over the 20-year studied period, 107 patients with primary periocular SCC were assessed. The mean age of SCC was 76.8 ± 12.8 years, 55 (50.9%) were females, and 105 (98.1%) had Fitzpatrick skin phenotype type II or III. SCC lesions affected less than 1/3 of the eyelid (56/52.3% cases), mainly the lower lid (42/39.3% lesions). Sixty (56.1%) cases were SCC differentiated, 76 (71%) had clear margins. Clinical diagnosis of SCC corroborated with histological in 84 (78.5%) cases and orbital involvement occurred in 18 (16.8%) cases. Recurrence was observed in 13 (12.1%) cases, occurring more in large tumors and undifferentiated subtype (53.8%), with committed margins (69.2%) (p = 0.001), being the commitment of margins a significant predictor for recurrence, although thickness was an independent predictor. CONCLUSION Periocular SCC in Spain showed a similar pattern as in the world. The risk of recurrence is increased in undifferentiated and large periocular SCC, partially removed with committed margins.

Abstract
Focal eosinophilic myositis (FEM) is a rare disease that is even more uncommon in affecting the periocular area. The authors are reporting the first case of FEM occurring in the lower eyelid of a 45-year-old Caucasian female who presented with localized painful area of glossy induration and peau d'orange skin lesion. Magnetic resonance image shows significant hyperintense thickening of the pre-septal orbicularis muscle region on T2-weighted images. Incisional biopsy of the induration revealed marked fibrinoid degeneration of the orbicularis muscle and adjacent fascia, mixed cellular infiltration of lymphocytes and eosinophils and a predominant CD8+ lymphocytic infiltrates in the immunohistochemical study. The final diagnosis was FEM. Oral prednisolone improved symptoms and the lesions disappeared, with no recrudescence in a one year follow-up.

Abstract
Purpose: To define the incidence, characteristics, and management of eyelid basal cell carcinoma (BCC) in Central Spain. Methods: This retrospective study investigates the characteristics and the outcome of eyelid BCC from 2000 to 2016 in a central region of Spain. Data were collected on demographics, skin phenotype, location of the eyelid lesion, clinical and histological diagnosis, surgery, commitment of surgical margins, and recurrence rate. Results: Primary eyelid BCC occurred in a mean of 20.6 lesions a year or 9.4/100,000 inhabitants/year. The mean age of BCC carriers was 69.4 ± 16.2 years, with no gender difference (P = 0.479), predominantly affecting Fitzpatrick II–III skin (81.3%) (P < 0.001). The most common location was the inner canthus (154/45.7%) (P < 0.001) and type nodular (215 cases/63.8%) (P < 0.001). The surgical margins were affected in 69 (20.5%) individuals, and the recurrence rate was 5.6 (95% confidence interval, 3.2–8.3) significantly higher in affected margins (P < 0.001). The most common location for recurrence was the inner canthus (P = 0.003), and the most common histological type for recurrence was sclerosing (16.7%), then multinodular (12.5%), and infiltrating (10.4%) with no significant difference (P = 0.27). Conclusions: The frequency of occurrence of eyelid BCC is much less than the estimated crude incidence for skin tumors involving all areas of the body in the Spanish population. Eyelid BCC is more common in the seventh decade of life, with no predilection for gender. Nodular histological type is the most common. The recurrence rate is 5.6%, depending on site and affected margins, even though clear free margins also can present with recurrence.

Abstract
PURPOSE: To report the epidemiological data, clinical profile, management, and outcomes of canalicular lacerations in the pediatric age group in a tertiary eye care hospital in Saudi Arabia. METHODS: This retrospective study evaluated pediatric patients who underwent canalicular laceration repair in the last 15 years at King Khalid Eye Specialist Hospital (KKESH), Saudi Arabia. Demographics, causes of injury, type of trauma, surgical approach, and outcomes were analyzed. The success of repair was defined as the absence of epiphora after canaliculus repair with negative dye disappearance test (DDT). Success within subgroups was compared. P < 0.05 was considered statistically significant. RESULTS: The study sample was comprised of 43 patients, with a median age of 6.35 years (range, 1.77–17.96 years). Most of the patients were males (69.8%). Sharp objects were the most common cause of canalicular laceration (46.5%), being 9 (20.9 %) caused by a metallic clothing hanger. Lower canaliculus was involved in 65.1%, upper canaliculus in 32.6%, and both canaliculi in 2.3% of patients. Canaliculus repair was performed with a bicanalicular stent in 58.1 % and monocanalicular stent in 41.9 % of patients.The success rate and risk of complications using bicanalicular or monocanalicular stent did not differ (P = 0.065). Functional success was achieved in 87.5% of patients. CONCLUSION: Canalicular laceration is common in male children, mainly affecting the lower canaliculus. There was no difference in success rate between monocanalicular and bicanalicular stent. As canalicular laceration could be related to social determinants, the main causes should be highlighted in community health education initiatives.

Abstract
PURPOSE To determine the frequency of ocular conditions among patients presenting to an emergency department at a tertiary hospital in Spain. METHODS A retrospective, longitudinal analysis of all patients who presented to the ocular emergency department of Rio Hortega University Hospital, Valladolid, Spain, from 2013 to 2018 was performed. Data on demographics, ophthalmic examination, and diagnosis were collected. Diseases were classified according the International Classification of Diseases, Ninth Revision, Clinical Modification codes. RESULTS We had 20,822 patients, of which 10,878 (52.2%) were women. The main age categories were 45-65 years (7391 patients; 35.5%) and 15-45 years (5979 patients; 28.2%). Most of the patients (17,793; 85.5%) were discharged on the same day. Conjunctival pathology was the most common cause of presentation (4110; 19.7%), followed by corneal disorders (4025; 19.3%). Acute conjunctivitis was diagnosed in 2920 (14%) and ocular trauma in 2125 (10.2%) patients. Non-emergency ophthalmic conditions were diagnosed in 1581 (7.6%) patients. Retinal detachments and peripheral holes occurred more commonly in patients aged 45-65 years (p <0.001). Corneal or conjunctival disorders and lid inflammation (p <0.001) were more frequent in women, whereas men had higher incidences of trauma (p <0.001). CONCLUSION Most of our patients presented ocular surface diseases. Men were more vulnerable to trauma, mainly superficial foreign body. The majority of the patients presented with uncomplicated ocular conditions that would be managed more cost-effectively by primary health care providers. We advocate greater education of primary care physicians and patients in managing simple ocular emergencies to reduce the cases presenting to an emergency department of a tertiary hospital.

Abstract
We report a case of a young healthy patient who developed orbital cellulitis and scleritis after retinal detachment surgery that was repaired with a scleral buckling procedure. Once scleral implant infection occurs, orbital infection results requiring removal of the implant in all previous reported cases. However, our patient was treated with systemic antibiotic and steroids without the need for removal of the scleral buckle.

Abstract
PURPOSE To provide a focused review of sickle cell retinopathy in the light of recent advances in the pathogenesis, multimodal retinal imaging, management of the condition, and migration trends, which may lead to increased prevalence of the condition in the Western world. METHODS Non-systematic focused literature review. RESULTS Sickle retinopathy results from aggregation of abnormal hemoglobin in the red blood cells in the retinal microcirculation, leading to reduced deformability of the red blood cells, stagnant blood flow in the retinal precapillary arterioles, thrombosis, and ischemia. This may be precipitated by hypoxia, acidosis, and hyperosmolarity. Sickle retinopathy may result in sight threatening complications, such as paracentral middle maculopathy or sequelae of proliferative retinopathy, such as vitreous hemorrhage and retinal detachment. New imaging modalities, such as wide-field imaging and optical coherence tomography angiography, have revealed the microstructural features of sickle retinopathy, enabling earlier diagnosis. The vascular growth factor ANGPTL-4 has recently been identified as a potential mediator of progression to proliferative retinopathy and may represent a possible therapeutic target. Laser therapy should be considered for proliferative retinopathy in order to prevent visual loss; however, the evidence is not very strong. With recent development of wide-field imaging, targeted laser to ischemic retina may prove to be beneficial. Exact control of intraoperative intraocular pressure, including valved trocar vitrectomy systems, may improve the outcomes of vitreoretinal surgery for complications, such as vitreous hemorrhage and retinal detachment. Stem cell transplantation and gene therapy are potentially curative treatments, which may prevent retinopathy. CONCLUSIONS There is lack of evidence regarding the optimal management of sickle retinopathy. Further study is needed to determine if recent progress in the understanding of the pathophysiology and diagnosis of sickle retinopathy may translate into improved management and outcome.

Abstract
This study aims to describe a case of double lower lacrimal punctum-canaliculi in a dry eye patient treated with a punctal plug. A 60-year-old healthy female presented with complaints of tearing, itchy eyes, and foreign body sensation in the right eye for many years. There was no history of trauma or inflammation. Two patent independent supernumerary puncta and canaliculi were present on the right lower eyelid. The Schirmer Test II (with anesthesia) was zero, the tear breakup time was 2 s, and superficial punctate erosions were present in the right eye. A long-term nonabsorbable punctal plug was inserted into one of the lower puncta. At 9-month follow-up, the dry eye symptoms decreased markedly, the Schirmer Test II improved and superficial keratitis resolved.

Abstract
PURPOSE To evaluate the demographic, clinical, and histopathologic characteristics of periocular inverted follicular keratosis (IFK), a very rare lesion with poorly defined characteristics. STUDY DESIGN Retrospective case series. METHODS We evaluated 11 patients with clinically diagnosed IFK confirmed by histologic analysis. Data were collected on the patients' demographics, clinical presentation and course of the disease, signs and symptoms, location of the lesion, and outcomes of treatment. RESULTS The patients' mean age was 71 years (range, 32-91 years). Seven (64%) of the patients were female. Eight of the patients (72.7%) had no symptoms, two (18.2%) reported itching, and one (9.1%) had edema and bleeding of the lesion. The lesion affected the upper eyelid in 4 of the patients (36%), the lower lid in 3 of the patients (27%), and the inner canthus in 4 of the patients (36%). CONCLUSIONS IFK has no specific clinical characteristic and thus requires histologic confirmation for its diagnosis and appropriate management.

Abstract
PURPOSE To investigate potential risk factors for the progression of myopia. METHODS Prospective study. Myopic progression was evaluated by cycloplegic autorefraction and axial length (AL) every 6 months in children 6 to 15 years old. Univariate analysis and multiple logistic regression were applied. RESULTS Around 82 children with median age of 10.3±2.3 years. Myopia progressed by -0.816±0.6 D over 18 months. Increased myopic spherical equivalent refraction (SER) was correlated with increase in AL (P<0.001). Univariate analysis found SER to be significantly associated with: age, especially between 6 and 9.4 years old (P=0.001), parental myopia (P=0.028), and less time spent outdoors (P=0.009). There was a significantly greater increase in SER during months with the least daylight hours (P<0.001). CONCLUSION Outdoor activities and daylight have a protective effect against increased AL and progression of myopia. Younger children with significant myopia should be monitored closely, especially those around 6 years old with myopic parents.

Abstract
BACKGROUND To evaluate the success rates of endoscopic-assisted probing compared to conventional probing in children 48 months or older. METHODS This retrospective study included children 48 months and older with CNLDO who underwent endoscopic-assisted probing or conventional probing between January 2011 to August 2015 at a tertiary eye care hospital in central Saudi Arabia. Probing was considered successful when signals of tearing or discharge disappeared and fluorescein dye disappearance test (FDDT) was normal. Demographic data, clinical features, intraoperative and postoperative variables were correlated to the success rate. RESULTS One hundred and twelve children with CNLDO undergoing endoscopic-assisted (37 patients) or conventional (75 patients) probing were included. The success rates of endoscopic-assisted and conventional probing were 94.6% [95% confidence interval (CI): 89.5-99.7] and 58.7% [95% (CI): 47.6-69.8], respectively. The success rate was higher with endoscopic probing, especially in older children. CONCLUSIONS Endoscopic-assisted probing can achieve better outcomes to treat CNLDO, even in older children. The significantly higher success rates with endoscopic probing are likely due to the ability to observe and treat associated problems.

Abstract
AIM To present a method of screening for irregular astigmatism with an autorefractor and its determinants compared to corneal topography. METHODS This cross-sectional validity study was conducted in 2013 at an eye hospital in Spain. A tabletop autorefractor (test 1) was used to measure the refractive status of the anterior surface of the cornea at two corneal meridians of each eye. Then corneal topography (test 2) and Bogan's classification was used to group eyes into those with regular or no astigmatism (GRI) and irregular astigmatism (GRII). Test 1 provided a single absolute value for the greatest cylinder difference (Vr). The receiver operating characteristic (ROC) were plotted for the Vr values measured by test 1 for GRI and GRII eyes. On the basis a Vr value of 1.25 D as cut off, sensitivity, specificity were also calculated. RESULTS The study sample was comprised of 260 eyes (135 patients). The prevalence of irregular astigmatism was 42% [95% confidence interval (CI): 36, 48]. Based on test 2, there were 151 eyes in GRI and 109 eyes in GRII. The median Vr was 0.75 D (25% quartile, 0.5 D) for GRI and 1.75 D (25% quartile, 1.25 D) for GRII. The area under curve was 0.171 for GRI and 0.83 for GRII. The sensitivity of test I was 78.1% and the specificity was 76.1%. CONCLUSION A conventional autorefractor can be effective as a first level screening method to detect irregular corneal astigmatism in places where corneal topography facilities are not available.

Abstract
Distichiasis is a condition clinically presenting as partial or complete accessory row of lashes that emerges from the meibomian glands orifices. It can be an acquired or congenital with an autosomal dominant inheritance. The histopathological features are not well described in the ophthalmic literature, however they include abnormal pilosebaceous units within the posterior lamella of the eyelid and perifollicular chronic inflammatory cell infiltration. In this report, we describe the histopathological findings of three congenital distichiasis cases treated at King Khaled Eye Specialist Hospital (KKESH), Riyadh, Saudi Arabia with discussion on the pathogenesis of such a condition and the differentiating features from ectopic cilia.

Abstract
PURPOSE To compare outcomes of two techniques of frontalis silicone sling surgery. METHODS This retrospective, nonrandomized chart review was performed on patients undergoing frontalis sling surgery between 2008 and 2011. Silicone rods were sutured to the tarsal plate through an eyelid crease incision (open method) or stab incisions (closed method). Data were collected on age, gender, type of surgery, preoperative and postoperative margin reflex distance (MRD), and complications. A successful outcome was defined as a postoperative score of 2 to 4 for MRD or an improvement in MRD. RESULTS A total of 155 eyelids of 146 patients with ptosis were included. There were 60 patients in the open method group and 85 patients in the closed method group, respectively. Successful outcomes were seen in 30 (50%) patients in the open method and 44 (51.8%) patients in the closed method groups. There were 61 (71.8%) patients in the open method group and 45 (75%) patients in the closed method group who had improved MRD at last follow-up. The main complications were exposure keratitis, eyelash ptosis, and eyelid crease abnormalities that occurred only in the closed method group. CONCLUSIONS The silicone frontalis sling procedure had the same success rates in both the open and closed methods. Eyelash and eyelid crease abnormalities were unique to the closed method.

Main visual symptoms associated to refractive errors and spectacle need in a Brazilian population. Int J Ophthalmol 2016; 9:1657-1662. [PMID: 27990372 DOI: 10.18240/ijo.2016.11.20] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2015] [Accepted: 01/22/2016] [Indexed: 11/23/2022] Open
Abstract
AIM To determine the main visual symptoms in a Brazilian population sample, associated to refractive errors (REs) and spectacle need to suggest priorities in preventive programs. METHODS A cross-sectional study was conducted in nine counties of the southeast region of Brazil, using a systematic sampling of households, between March 2004 and July 2005. The population was defined as individuals aged between 1 and 96y, inhabitants of 3600 residences to be evaluated and 3012 households were included, corresponding to 8010 subjects considered for participation in the survey, of whom 7654 underwent ophthalmic examinations. The individuals were evaluated according their demographic data, eye complaints and eye examination including the RE and the need to prescribe spectacles according to age. Statistical analysis was performed using SPSS software package and descriptive analysis using 95% confidence intervals (P<0.05). RESULTS The main symptom detected was asthenopia, most frequent in the 2nd and 3rd decades of life, with a significant decline after the 4th decade. Astigmatism was the RE most associated with asthenopia. Reduced near vision sight was more frequent in those ≥40y with a progressive decline thereafter. Spectacles were most frequently required in subjects of ≥40 years of age. CONCLUSION The main symptom related to the vision was asthenopia and was associated to astigmatism. The greatest need for spectacles prescription occurred after 40's, mainly to correct near vision. Subjects of ≥40 years old were determined to be at high risk of uncorrected REs. These observations can guide intervention programs for the Brazilian population.

Abstract
BACKGROUND Anophthalmia is the absence of one or both eyes, and it can be congenital (i.e. a birth defect) or acquired later in life. There are two main types of orbital implant: integrated, whereby the implant receives a blood supply from the body that allows for the integration of the prosthesis within the tissue; and non-integrated, where the implant remains separate. Despite the remarkable progress in anophthalmic socket reconstruction and in the development of various types of implants, there are still uncertainties about the real roles of integrated (hydroxyapatite (HA), porous polyethylene (PP), composites) and non-integrated (polymethylmethacrylate (PMMA)/acrylic and silicone) orbital implants in anophthalmic socket treatment. OBJECTIVES To assess the effects of integrated versus non-integrated orbital implants for treating anophthalmic sockets. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 7), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to August 2016), Embase (January 1980 to August 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to August 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 8 August 2016. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs of integrated and non-integrated orbital implants for treating anophthalmic sockets. DATA COLLECTION AND ANALYSIS Two authors independently selected relevant trials, assessed methodological quality and extracted data. MAIN RESULTS We included three studies with a total of 284 participants (250 included in analysis). The studies were conducted in India, Iran and the Netherlands. The three studies were clinically heterogenous, comparing different materials and using different surgical techniques. None of the included studies used a peg (i.e. a fixing pin used to connect the implant to the prosthesis). In general the trials were poorly reported, and we judged them to be at unclear risk of bias.One trial compared HA using traditional enucleation versus alloplastic implantation using evisceration (N = 100). This trial was probably not masked. The second trial compared PP with scleral cap enucleation versus PMMA with either myoconjunctival or traditional enucleation (N = 150). Although participants were not masked, outcome assessors were. The last trial compared HA and acrylic using the enucleation technique (N = 34) but did not report comparative effectiveness data.In the trial comparing HA versus alloplastic implantation, there was no evidence of any difference between the two groups with respect to the proportion of successful procedures at one year (risk ratio (RR) 1.02, 95% confidence interval (CI) 0.95 to 1.09, N = 100, low-certainty evidence). People receiving HA had slightly worse horizontal implant mobility compared to the alloplastic group (mean difference (MD) -3.35 mm, 95% CI -4.08 to -2.62, very low-certainty evidence) and slightly worse vertical implant motility (MD -2.76 mm, 95% CI -3.45 to -2.07, very low-certainty evidence). As different techniques were used - enucleation versus evisceration - it is not clear whether these differences in implant motility can be attributed solely to the type of material. Investigators did not report adverse events.In the trial comparing PP versus PMMA, there was no evidence of any difference between the two groups with respect to the proportion of successful procedures at one year (RR 0.92, 95% CI 0.84 to 1.01, N = 150, low-certainty evidence). There was very low-certainty evidence of a difference in horizontal implant motility depending on whether PP was compared to PMMA with traditional enucleation (MD 1.96 mm, 95% CI 1.01 to 2.91) or PMMA with myoconjunctival enucleation (-0.57 mm, 95% CI -1.63 to 0.49). Similarly, for vertical implant motility, there was very low-certainty evidence of a difference in the comparison of PP to PMMA traditional (MD 3.12 mm 95% CI 2.36 to 3.88) but no evidence of a difference when comparing PP to PMMA myoconjunctival (MD -0.20 mm 95% CI -1.28 to 0.88). Four people in the PP group (total N = 50) experienced adverse events (i.e. exposures) compared to 6/100 in the PMMA groups (RR 17.82, 95% CI 0.98 to 324.67, N = 150, very low-certainty evidence).None of the studies reported socket sphere size, cosmetic effect or quality of life measures. AUTHORS' CONCLUSIONS Current very low-certainty evidence from three small published randomised controlled trials did not provide sufficient evidence to assess the effect of integrated and non-integrated material orbital implants for treating anophthalmic sockets. This review underlines the need to conduct further well-designed trials in this field.

Success Rates of Conventional Versus Endoscope-Assisted Probing for Congenital Nasolacrimal Duct Obstruction in Children 12 Years and Younger. J Pediatr Ophthalmol Strabismus 2016; 53:292-9. [PMID: 27383144 DOI: 10.3928/01913913-20160610-02] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2015] [Accepted: 04/05/2016] [Indexed: 11/20/2022]
Abstract
PURPOSE To compare the success rates for congenital nasolacrimal duct obstruction (CNLDO) treated with conventional probing versus endoscope-assisted probing. METHODS A retrospective nonrandomized comparison of the success rates in children (0 to 12 years) with CNLDO who underwent conventional probing or endoscope-assisted probing. Success was defined as absence of tearing or negative fluorescein dye disappearance test. Stent was evaluated. RESULTS A total of 270 patients with CNLDO comprised the study population. The mean age was 37 months in the conventional probing group and 48.5 months in the endoscope-assisted probing group. The subjective and objective success rates were 76.1% and 75.9%, respectively, in the conventional probing group and 95.7% and 95.7%, respectively, in the endoscope-assisted probing group. The success rates were higher for both methods in the endoscope-assisted probing group (P < .005). The success rate decreased in older children in the conventional probing group (100% < 6 months; 62.5% > 48 months) and remained stable in the endoscope-assisted probing group (100% < 6 months; 97% > 48 months). Stent did not improve success. CONCLUSIONS Endoscope-assisted probing increased success in older children and children with bilateral obstruction.

Abstract
PURPOSE To assess the efficacy and safety of porous and nonporous implants for management of the anophthalmic socket. METHODS Case series meta-analysis was conducted with no language restriction, including studies from: PUBMED, EMBASE and LILACS. Study eligibility criteria were case series design with more than 20 cases reported, use of porous and/or nonporous orbital implants, anophthalmic socket and, treatment success defined as no implant exposure or extrusion. Complications rates from each included study were quantified. Proportional meta-analysis was performed on both outcomes with a random-effects model and the 95% confidential intervals were calculated. RESULTS A total of 35 case series studies with a total of 3,805 patients were included in the meta-analysis. There are no studies comparing porous and nonporous implants in the anophthalmic socket treatment. There was no statistically significant difference between porous polyethylene (PP) and hydroxyapatite (HA) on implant exposure: 0.026 (0.012-0.045) vs 0.054 (0.041-0.070), respectively and, neither on implant extrusion: 0.0042 (0.0008-0.010) vs. 0.018 (0.004-0.042), respectively. However, there was a significant difference supporting the use of PP when compared to bioceramic implant: 0.026 (0.012 -0.045) vs. 0.12 (0.06-0.20), respectively, on implant exposure. CONCLUSION PP implants showed lower chance of exposure than bioceramic implant for anophthalmic socket reconstruction, although we cannot rule out the possibility of heterogeneity bias due to the nature and level of evidence of the included studies. Clinical trials are necessary to expand the knowledge of porous and nonporous orbital implants in the anophthalmic socket management.
