RESUMO
PURPOSE: To investigate the efficacy and safety of non-valved Aurolab aqueous drainage implant (AADI) surgery combined with phacoemulsification in eyes with refractory glaucoma and coexistent cataract. METHODS: Included patients of 18 years or older who underwent combined AADI-Phacoemulsification from June 2015 to January 2017 with at least 12 months of consecutive follow-up. The best-corrected visual acuity, intraocular pressure (IOP), and the number of IOP-lowering medications were recorded at baseline, 2 weeks, 1, 3, 6, 12, 18, and 24 months. Cumulative probability of success was defined as IOP < 18 mmHg or 30% reduction from the baseline at two consecutive postoperative visits after 3-months. Loss of light perception or reoperation for uncontrolled glaucoma or a complication was considered failure apart from IOP criteria. RESULTS: Seventeen eyes of 17 patients with a mean follow-up of 22.6 ± 4.0 months were included. Baseline IOP and ocular hypotensive drugs reduced significantly from 27.9 ± 7.6 mmHg to 14.0 ± 3.0 mmHg (p < 0.001) and 3.24 ± 0.7 to 1.33 ± 1.1 (p = 0.001), respectively, at 24 months. Cumulative probability of qualified success was 71.4% (95% Confidence Interval [CI] 40.6-88.2%) at 3 months and was maintained from 6 months onwards at 64.3% (95% CI 34.3-83.3%), up to 2 years. Intravitreal steroid was injected in one eye (5.9%) of chronic cystoid macular edema, and tube repositioning was done in another for focal corneal decompensation. CONCLUSIONS: Combined AADI-Phacoemulsification surgery is a safe and effective option in providing favorable visual and IOP outcomes at an affordable cost in eyes with refractory glaucoma and coexistent cataract.

PURPOSE: To evaluate the severity of primary open angle glaucoma (POAG) at presentation using visual field analysis and its relationship to demographic and ocular factors in patients presenting to a tertiary eye care centre. DESIGN: Cross-sectional study. METHODS: Newly diagnosed POAG patients were classified as early, moderate, or severe stage in the worse eye based on the Humphrey visual field testing using Hodapp-Parrish-Andersons criteria. The groups were compared for differences in demographics and ocular characteristics. Statistical analysis was done using STATA 14.1 (Texas, USA). RESULTS: The average age of 71 eligible patients was 60.04 ± 9.53 years, and the cohort had 29.5% females. Among the subjects, 19 (26.7%) had early, 24 (33.3%) had moderate and 28 (38.89%) had severe POAG at presentation. There was no statistically significant difference among different stages of glaucoma with respect to age and sex groups. No statistical association was found with education, occupation status, presenting complaints, family history of glaucoma, or systemic diseases between the different stages of severity. 5.6% with severe disease presented with a relative afferent pupillary defect (RAPD). The mean intraocular pressure (IOP) in the severe stage was 22.54 ± 5.27 mmHg, which was not statistically higher than the other groups (P = 0.726). CONCLUSIONS: Newly diagnosed POAG patients predominantly present at moderate or severe stage of disease, reflecting either the asymptomatic nature of the disease or a lack of access to vision care services. Existing screening programmes need to be improved, with special attention to women and individuals less than 50 years of age.

AIM/PURPOSE: To report the incidence, risk factors, and magnitude of steroid response in individuals receiving topical 1% prednisolone acetate eye drops following phacoemulsification surgery MATERIALS AND METHODS: Postoperative IOP of 1118 consecutive patients who had uneventful cataract surgery and used 1% topical prednisolone acetate were studied. Baseline ocular parameters like best-corrected visual acuity, IOP, and slit-lamp examination findings were noted preoperatively and at postoperative day 30. Incidence of postoperative intraocular pressure response to steroid was analyzed and graded as mild, moderate, or severe and risk factors studied. RESULTS: The mean age of our study cohort was 59.49 ± 7.25 years. The overall incidence of steroid response was 3.2%, (2.8% being moderate responders, and 0.4% high responders). Mean preoperative IOP was 14.67 ± 2.2 mm Hg in the study cohort (n = 1118). Mean postoperative IOP was 21.33 ± 7.97 mm Hg in the steroid responder (SR) and 14.66 ± 2.8 mm Hg in the non-responder (NR), with a statistically significant difference from the baseline IOP in the SR group (p < 0.001) and no difference in the NR. Univariate analysis revealed younger age and high axial length as risk factors but on multiple regression analysis, only younger age < 50 years was found to be a significant risk factor for steroid response. CONCLUSION: The overall steroid response in this population post-cataract surgery was low with most being moderate responders. Younger age and higher axial length were identified as risk factors for steroid response, and hence this warrants the judicious use of steroids in such individuals.

UNLABELLED: An effective preventive vaccine is highly sought after in order to stem the current HIV-1 pandemic. Both conservation of contiguous gp41 membrane-proximal external region (MPER) amino acid sequences across HIV-1 clades and the ability of anti-MPER broadly neutralizing antibodies (BNAbs) to block viral hemifusion/fusion establish the MPER as a prime vaccination target. In earlier studies, we described the development of an MPER vaccine formulation that takes advantage of liposomes to array the MPER on a lipid bilayer surface, paralleling its native configuration on the virus membrane while also incorporating molecular adjuvant and CD4 T cell epitope cargo. Here we demonstrate that several immunizations with MPER/liposomes induce high levels of bone marrow long-lived plasma cell (LLPC) antibody production. Single-cell immunoglobulin gene retrieval analysis shows that these plasma cells are derived from a germ line repertoire of B cells with a diverse representation of immunoglobulin genes, exhibiting antigen-driven positive selection. Characterization of LLPC recombinant monoclonal antibodies (rMAbs) indicates that antigen recognition is achieved through convergence on a common epitopic focus by utilizing various complementarity-determining region H3 (CDRH3) lengths. Importantly, the vast majority of rMAbs produced from these cells lack polyreactivity yet manifest antigen specificity in the context of lipids, shaping MPER-specific paratopes through selective pressure. Taken together, these findings demonstrate that the MPER is a vaccine target with minimal risk of generating off-target autoimmunity. IMPORTANCE: A useful vaccine must generate desired long-term, antigen-specific antibody responses devoid of polyreactivity or autoreactivity. The common polyreactive features of some HIV-1 BNAbs have raised concern about elicitation of anti-MPER antibodies. Utilizing single-LLPC repertoire analysis and biophysical characterization of anti-MPER rMAbs, we show that their fine specificities require a structural fitness of the antibody combining site involving heavy and light chain variable domains shaped by somatic hypermutation and affinity maturation of B cells in the germinal center. Perhaps more importantly, our results demonstrate that the majority of MPER-specific antibodies are not inherently polyspecific and/or autoreactive, suggesting that polyreactivity of MPER-specific antibodies is separable from their antigen specificity.

Purpose: The objective of the present study was to investigate the relationship between macular pigment optical density (MPOD) and plasma carotenoids [(L) and (Z)] and serum lipids in South Indian young healthy volunteers and patients with early age-related macular degeneration (AMD). Methods: Two hundred and fourteen (N = 214) study participants (Healthy control group (N) = 178; Early AMD group (N) = 36) were enrolled after getting their written informed consent. The MPOD of the study participants was assessed using MPS II (Electron Technology, UK) after completing their routine ocular examination. Serum lipids were measured by the standard technique. Plasma levels of L, Z, lycopene and beta-carotene were estimated by high performance liquid chromatography with photo diode array detector. Statistical analysis used: Correlations among variables in serum, plasma and the MPOD were established using Spearman's rho correlation coefficient. Results: The overall mean MPOD in healthy control group and early AMD group were found to be 0.47 ± 0.16 (N = 178; 317 eyes) and 0.35 ± 0.22 (N = 36; 38 eyes) at 1° eccentricity respectively and were found to be statistically significant (p < 0.001). A strong positive association was found between plasma L, Z and L + Z and MPOD. Serum HDL showed a strong negative association with MPOD and other lipids showed a very weak association. MPOD was unaffected by body mass index. Conclusions: MPOD is positively associated with plasma L,Z and L + Z, adding further evidence that additional intake of L/Z may be beneficial in delaying the risk of AMD in our population.
RESUMO
PURPOSE: To assess the clinical outcomes of symblepharon release in patients with ocular surface chemical injury using Gore-Tex as a novel treatment option. METHODS: This was a retrospective analysis of 23 eyes of 22 chemical injury patients done during a period of January 2014 to December 2021 at a tertiary eye care centre in South India. All patients underwent symblepharon lysis along with Gore-Tex application over the sclera with minimum 1 year follow up. The patients were assessed for demographic details, visual acuity, intraocular pressure, anterior and posterior segment details, photographic documentation, preoperative diagnosis, previous surgical details in recurrent cases, surgical procedures, final visual acuity, surgical outcomes, and complications. The clinical outcomes were assessed and outcomes were defined as success, partial success, or failure. RESULTS: The median age was 17 years (IQR, 12-39 years). Among them 10 eyes with symblepharon had grade 3 length, 12 eyes grade 3 width and 12 eyes had grade 3 loss of palisades of Vogt. The success was achieved in 52.2% of the patients; partial success in 34.8% and 13.3% had failure. The mean duration of recurrence was 6.75 ± 3.6 months. Failure was noted in young patients with mean age 9.75years and with grade 3c symblepharon. There was no sight threatening complications noted. CONCLUSION: The study showed very good results with Gore-Tex as a novel treatment option for chemical injury patient with symblepharon formation. It can be easily employed to prevent the symblepharon recurrence of various ocular surface disorders.
RESUMO
AIM: This study aims to profile the ocular biometric parameters in a large group of children of South-Indian ethnicity who visited our outpatient children's department and were diagnosed with myopia. METHODS: Children <15 years old diagnosed with myopia (Jan 2022-Oct 2023) and who had ocular biometry readings recorded were included. Their demographics, axial length (AL), anterior chamber depth (ACD), spherical equivalent (SE), corneal radius of curvature (CR), and AL/CR ratio were analyzed. RESULTS: The study included 3728 myopic children; the mean age was 11.85 (4-15) years, and 52.8% were girls. Mean SE was -3.98 D. The mean (SD) AL, ACD, CR, and AL/CR ratio were 24.64 (1.32), 3.73 (0.40), 7.61 (0.27), and 3.24 (0.16), respectively. Female gender was associated with shorter AL, ACD, CR, and AL/CR ratios (P < 0.001) across all age groups. There was a significant increase in ACD with age in both sexes (P < 0.001). A 1-unit (mm) increase in AL was associated with an SE increase of -1.65 D (CL: -1.70 to -1.60). AL/CR ratio could explain 71% of the total variance in SE (P < 0.001). SE showed a mild correlation with age (rho = 0.14, P < 0.001) and ACD (rho = -0.03, P = 0.041) and a stronger correlation with AL (rho = -0.68, P < 0.001) and AL/CR (rho = -0.83, P < 0.001). CONCLUSION: In this hospital-based study, AL and AL/CR ratios strongly correlate with SE, and the AL/CR better explains the total variance in SE than AL alone in children with myopia.
RESUMO
PRCIS: Long-term intraocular pressure control can be difficult to achieve in eyes with Sturge-Weber syndrome glaucoma. The most commonly performed primary surgery was trabeculotomyin early onset disease and tube shunt implantation in late onset disease. PURPOSE: To compare long-term surgical outcomes of glaucoma associated with Sturge-Weber syndrome (SWS) in eyes with early and late-onset disease. METHODS: Medical records of children with glaucoma associated with SWS who underwent surgical treatment between January 1990 and December 2018 were reviewed. Those diagnosed ≤2 years of age were categorized as early onset while those who were diagnosed >2 years of age were late onset. Failure was defined as intraocular pressure (IOP) >21 mm Hg or reduced <20% below baseline on 2 consecutive follow-up visits after 3 months, IOP ≤5 mm Hg on 2 consecutive follow-up visits, reoperation for glaucoma or a complication, or loss of light perception. RESULTS: Forty-three eyes of 36 children were studied, including 26 eyes in the early-onset group and 17 eyes in the late-onset group. The early-onset group more frequently presented with buphthalmos, corneal edema, and Haab striae, while late-onset group had higher baseline IOP, larger cup-to-disc ratio, and longer axial length. The most commonly performed primary surgery was trabeculotomy (50%) in early-onset group and tube shunt implantation (71%) in late-onset group. The cumulative probability of failure after 5 years follow-up was 50.6% in early-onset group and 50.9% in the late-onset group ( P =0.56). Postoperative complications occurred in 3 eyes (12%) in early-onset group and 11 eyes (65%) in late-onset group ( P <0.001). CONCLUSIONS: Early and late-onset SWS glaucoma may represent 2 entities with different pathogenetic mechanisms, clinical presentations, primary surgical choices, and outcomes, though this needs corroboration in future studies.

PURPOSE: To describe the clinical presentation and treatment outcomes of pupillary block glaucoma (PBG) following vitreoretinal surgery (VR surgery). MATERIAL AND METHODS: Retrospective observational study of 6941 patients, who underwent VR surgery at a tertiary eye care centre in South India between January 2015 and December 2019. Amongst them, clinical data of 61 patients who developed PBG were taken for statistical analysis. RESULTS: Mean (SD) age was 53.90 (13.4) years and the incidence of PBG was .87%. Median (IQR) time of onset of PBG following VR surgery was 3.33 (1.1-6.6) months and majority were pseudophakic (75%). PBG resolved with Nd:YAG laser peripheral iridotomy (LPI) alone in 50 (82%) patients, whereas 11(18%) patients required additional interventions like surgical iridectomy, trabeculectomy or diode laser cyclophotocoagulation (CPC) either as a stand-alone procedure or in combination with silicone oil removal (SOR). Mean (SD) intraocular pressure at the onset of PBG was 41.61 (14.5) mmHg, which reduced drastically following LPI to 24.28 (14.9) mmHg which further dropped significantly at 6 months follow up to 20.34 (13.9) mmHg. CONCLUSIONS: Incidence of secondary PBG after VR surgery was .87%, and we observed diabetes mellitus, combined cataract and VR surgery, use of 1000cs SO endotamponade, intraoperative endolaser and multiple VR surgical interventions as common associations. Majority of the patients with PBG after VR procedures resolved with LPI and medical management. Few individuals (18%) required additional laser or surgical intervention for IOP control.

PURPOSE: To contribute evidence about the effectiveness of dichoptic therapy in patients with mild to moderate amblyopia. METHODS: A retrospective study was conducted in patients enrolled for dichoptic therapy on the Bynocs AmblyGo platform (Kanohi Eye Pvt Ltd) from January to August 2023. Data collected included logarithm of the minimum angle of resolution best corrected visual acuity, anterior and posterior segment examination, fixation pattern, dynamic and cycloplegic refraction, orthoptic evaluation, and number of dichoptic therapy sessions. Visual acuity, binocularity, and stereopsis before and after therapy were analyzed. RESULTS: Of 59 patients (median age: 11 years, range: 5 to 30 years) enrolled, 34 (57.6%) had anisometropic amblyopia, 12 (20.3%) had ametropic amblyopia, 10 (17.0%) had strabismic amblyopia, and 3 (5.1%) had deprivation amblyopia. All 6 (10.2%) and 15 (22.4%) patients who had no binocular single vision for near and distance before therapy, respectively, attained normal binocular single vision on completion, except one who suppressed at distance. Twenty-one (75.0%) had improved near stereopsis, and 21 (60.0%) had improved distance stereopsis. Of 74 eyes treated, 61 (82.4%) had improved visual acuity and 73 (98.6%) improved in at least one tested parameter. A majority of these eyes had residual amblyopia after occlusion therapy. CONCLUSIONS: Dichoptic therapy improves visual acuity, binocularity, and stereoacuity in patients with amblyopia, including those older than 8 years, especially in partial deprivation, ametropic, and anisometropic amblyopia. {J Pediatr Ophthalmol Strabismus. 20XX;XX(X):XX-XX.].
RESUMO
PURPOSE: To analyze the reasons for declining corneal refractive laser correction procedures in patients presenting to tertiary eye care centers in Tamil Nadu, Southern India, and review the literature. METHODS: Retrospective case records of subjects presenting from January 2019 to December 2021 for refractive surgery workup were analyzed. Demographic details and refractive parameters of patients rejected for corneal refractive laser corrections (CRLC) were documented and reviewed. RESULTS: A total of 2358 patients presented for refractive surgery evaluation during the study period, and out of them, 395 patients (16.8%) were not considered ideal candidates for undergoing CRLC. The common reasons for rejecting the patients were unfit topography (n = 110, 27.8%), unstable refraction over a one-year duration (n = 9, 2.27%), low corneal thickness (n = 85, 21.5%), keratoconus (n = 5, 12.9%), and other ocular and systemic disorders (n = 48, 12.1%). CONCLUSION: There was a marked change in magnitude and rationalization for not performing either laser-assisted in situ keratomileusis (LASIK) or photorefractive keratectomy in our study. The reasons are unfit topography, keratoconus, and systemic disorders, which were diagnosed during pre-LASIK screening workup, being the most common cause for rejecting patients for corneal refractive corrections.

PRCIS: A pathogenic autosomal dominant MYOC mutation N480K detected in 6 generations of an Indian family is primarily responsible for juvenile open angle glaucoma (JOAG) and adult-onset primary open angle glaucoma (POAG), emphasizing the importance of screening this mutation at a younger age. PURPOSE: To screen myocilin mutations in a large South Indian family with early-onset JOAG and adult-onset POAG. METHODS: In a large South Indian family with 20 members, 8 members diagnosed as JOAG, 7 members as POAG, 4 members as JOAG suspect, and 1 member as POAG suspect were screened for myocilin ( MYOC) mutations using Sanger sequencing. Whole exome sequencing was performed on clinically suspected JOAG/POAG individuals. RESULTS: Myocilin gene mutation N480K (c.1440C>G) was detected in 20 family members, including proband, of whom 8 were JOAG and 7 were POAG patients, 3 were JOAG suspects, and 2 were unaffected. Among the unaffected carriers, 1 was less than 5 years old, and another was 25 years old. The earliest to develop the disease was a 10-year-old child. The penetrance of the mutation was 95% over 10 years of age. This family had JOAG/POAG suspects with no N480K MYOC mutation, and they were further screened for other mutations using whole-exome sequencing. Polymorphisms CYP1B1 L432V and MYOC R76K were detected in 3 JOAG/POAG suspects, and among these 3, one had another CYP1B1 polymorphic variant R368H. The presence of the CYP1B1 polymorphism along with an MYOC polymorphic variant among the JOAG/POAG suspects needs additional studies to explore their combined role in the onset of glaucoma. CONCLUSIONS: This study reveals that MYOC mutation is primarily responsible for JOAG and adult-onset POAG in a family, emphasizing the importance of screening for this mutation at a younger age for early treatment.

OBJECTIVES: To evaluate the accuracy of tele-ophthalmic examination (TOE) for common ocular conditions in comparison with the gold-standard in-person examination (IPE) for diagnosis and treatment advice. METHODS: In a prospective, diagnostic accuracy validation study, we recruited 339 consecutive new patients, aged ≥16 years, visiting a vision centre (VC) associated with Aravind Eye Hospital in south India during January and February, 2020. All participants underwent the TOE, followed by IPE on the same visit. The in-person ophthalmologist was masked to the TOE diagnosis and treatment advice. Data were analysed via the sensitivity specificity of TOE versus the gold-standard IPE. RESULTS: TOE achieved high sensitivity and specificity for identifying normal eyes with 87.4% and 93.5%, respectively. TOE had high sensitivity for cataracts (91.7%), infective conjunctivitis (72.2%), and moderate sensitivity for pterygium (62.5%), DR (57.1%), non-serious injury (41.7%), but low sensitivity for glaucoma (12.5%). TOE had high specificity ranging from 93.5% to 99.8% for all diagnoses. The sensitivity for treatment advice ranged from 58.1% to 77.2% and specificity from 96.9% to 100%. CONCLUSIONS: The TOE in VCs has acceptable accuracy to an IPE by an ophthalmologist for correctly identifying and treating major eye ailments. Through providing universal eye care to rural populations, this model may contribute to work toward achieving Universal Health Coverage, which is a linchpin of the health-related U.N. Sustainable Development Goals (SDG).

PURPOSE: To study the early postoperative efficacy and safety of 5-0 Prolene gonioscopy-assisted transluminal trabeculotomy (GATT) combined with phacoemulsification in Indian eyes. METHODS: This was a prospective, interventional study. Patients with primary and secondary glaucoma who underwent GATT combined with phacoemulsification (Phaco-GATT) or standalone GATT were included. All patients were evaluated on postoperative days 1, 15, and 30, as well as 3 months and 6 months postoperatively. Baseline and follow-up visits were compared to determine the significant difference in the number of intraocular pressure (IOP), antiglaucoma medications (AGM), and best corrected visual acuity (BCVA). Other outcome measures included surgical success, complications, and interventions. A P value of < 0.05 was considered statistically significant. RESULTS: One hundred and five eyes (95 patients) were included. Seventy-five eyes underwent GATT along with phacoemulsification and 30 eyes underwent GATT. In the Phaco-GATT group, the mean IOP reduced significantly from 17.71 ± 6.85 to 12.29 ± 4.44, 12.33 ± 4.44, and 12.18 ± 3.49 mmHg and in the GATT group, it reduced from 21.67 ± 11.42 mmHg to 16.38 ± 8.42, 16.47 ± 10.26, and 13.10 ± 3.25 mmHg at 1, 3, and 6 months, respectively (P < 0.001). The number of AGM also significantly reduced from 1.67 ± 1.22 to 0.41 ± 0.87 and 0.34 ± 0.82 in the phaco-GATT group and from 2.63 ± 1.19 to 0.67 ± 1.09 and 0.60 ± 1.25 in the GATT group at 3 and 6 months, respectively (P < 0.001). Complete success (IOP > 6-≤21 mmHg/20% reduction without AGM) was 96.7% in the Phaco-GATT group and 91.2% in the GATT group. BCVA improved from log of minimum angle of resolution 0.30 to 0.00 (P < 0.001) in phaco-GATT group. Hyphema was the most common complication. Macrohyphema (>1 mm) was seen in six patients, out of which two patients required anterior chamber wash. IOP spikes (>30 mmHg) were seen in three patients. CONCLUSION: In Indian eyes, GATT combined with phacoemulsification and standalone GATT are efficacious and safe with good surgical outcomes.
RESUMO
PURPOSE: To assess the effect of Glaucoma awareness, knowledge, and anxiety on patients under visual field analysis by Humphrey's visual field analyzer (HFA) and optical coherence tomography(OCT). METHODS: This prospective comparative cohort study included glaucoma patients undergoing HFA (Group A)(n = 150) and OCT(Group B) (n = 150). Each group consisted of 75 newly diagnosed patients and 75 patients who were on follow-up. Participants completed State trait anxiety inventory form Y2(STAI) before and after the test to assess pre-test and intra-test anxiety. Another validated and structured questionnaire was used to assess patient awareness and knowledge of glaucoma. Anxiety scores were used to make correlations and comparisons between the two groups and also against visual field reliability indices. The impact of awareness on anxiety scores and its correlation with reliability indices were also determined. RESULTS: Overall pretest and intratest anxiety scores in patients undergoing HFA were 52.39(9.5) and 52.45(8.6)and OCT 53.04(8.0) and 53.83(8.2) respectively.Pretest anxiety was less in follow-up patients of both groups(Group A-51.04,Group B-52.72).There was no statistically significant difference between the groups(pretest p = 0.52,Intratest p = 0.15). Anxiety score was found to be significantly high in female participants(54.07,p = 0.01)and those without awareness(p < 0.001). Patients with education of graduation and above in group B had significantly lower anxiety scores(p = 0.007). CONCLUSION: Anxiety levels induced by both diagnostic modalities HFA and OCT appear to be similar and it does not affect the reliability indices.Anxiety score was higher in female participants and participants lacking disease awareness.
RESUMO
Purpose: To compare the surgical outcomes of trabeculectomy with and without anti-metabolites in patients with juvenile open-angle glaucoma (JOAG). Methods: This retrospective comparative case series included 98 eyes of 66 patients with JOAG who underwent either trabeculectomy without anti-metabolites (group A, n = 53 eyes) or with anti-metabolites (group B, n = 45 eyes) with a minimum of 2 years follow-up. The main outcome measures were intra-ocular pressure (IOP), number of glaucoma medications, visual acuity, additional surgical interventions, surgical complications, and risk factors for failure. Surgical failure was defined as IOP >18 mmHg or failure to reduce IOP by <30% from the baseline value or IOP ≤5 mmHg or re-operation for refractory glaucoma or a complication or loss of light perception vision. Results: The mean post-operative IOP reduced significantly from baseline at all post-operative visits until 6 months and thereafter. The cumulative probability of failure at 2 years was 28.7% in group A [95% confidence interval (CI) = 17.6-44.8%] and 29.1% in group B (95% CI = 17.1-46.7%) (P = 0.78). Surgical complications occurred in 18 eyes (34%) in group A and 19 eyes (42%) in group B. Re-operations for glaucoma or complications were performed in two eyes (3.8%) in group A and two eyes (4.4%) in group B. Cox-hazard regression model revealed male gender (HR = 0.29; P = 0.008), baseline high IOP (HR = 0.95; P = 0.002), and an increased number of pre-operative glaucoma medications (HR = 2.08; P = 0.010) as significant factors associated with failure. Conclusion: : Our study results on trabeculectomy in JOAG revealed a success of 71% in both groups at 2 years follow-up. There was no significant difference in success or failure rates between the two groups. The risk factors for poor surgical outcome in JOAG were male gender, baseline high IOP, and an increased number of glaucoma medications.

Purpose: To study the clinical outcomes, time span of healing of various ocular surface disorders with amniotic membrane graft. Methods: A total of 41 patients, presenting to cornea clinic were included in the study and divided into five groups depending on the type of diagnosis: Group 1, with either >2 weeks of Persistent epithelial defect following cataract/retinal/glaucoma surgeries or Shield ulcers, Group 2 with >4 weeks of Non healing corneal ulcers, Group 3 with chemical injuries, Group 4 with Epithelial defects following keratoplasty, and Group 5 is the miscellaneous group. Results: The mean age of the study subjects was 50.0 years. Overall mean duration between clinical presentation and AMT was 23.59 (30.7) days, a median 16 days (IQR; 2-26 days). Failure rate was high in Group 5 (n = 3: 30.0%) and Group 2 (n = 3: 27.3%). Time taken for epithelial closure was slower in groups 1 and 5 patients. The average time taken for reabsorption of AMG was 14.98 days. The complications included repeat AMG was in four eyes (9.75%), and graft displacement was noted in four eyes (9.75%) required resuturing, three eyes required TPK (7.31%), and one eye underwent evisceration (2.43%) following severe corneal melt secondary to neurotropic ulcer. The mean log MAR visual acuity improved from 1.52 to 1.26 at the 3 months. Conclusion: Understanding on timespan for healing of ocular surface disorders with AMG is needed to assess the prognosis of the disease, preoperative counselling for repeat procedures, and the compliance with regard to follow up.

Purpose: To study the prevalence and determinants of compliance with spectacle wear among school-age children in South India who were given spectacles free of charge under a school vision screening program. Methods: A cross-sectional, descriptive study was performed. The participants were recruited from the school from Tirunelveli and Tuticorin districts of Tamil Nadu, where a school vision screening camp was conducted between January 2012 and October 2012. The school screening was performed under. "Lavelle Pediatric Eye Care Project": . Of the 129,720 children examined of 249 schools, 4253 of children had refractive error and 3333 were prescribed and dispensed spectacles. A total of 683 children were interviewed, who were not wearing glasses on follow-up. Results: About 20% of the participants (683/3333) were not wearing their spectacles at examination. The most common reasons given for non-wear were lost (44.9%) or broken (35.3%) spectacles. There was no gender preference on compliance to spectacles. Conclusion: Compliance with spectacle wear is less even when spectacles are provided free of cost, particularly in children among the age group of 5-15 years. Because factors such as type of school, area (urban or rural), parent's income, occupation, and their education were not significantly affecting the compliance of spectacle wear, proper encouragement and counseling of the parents and the child become extremely important.

Purpose: To find out parents' knowledge, attitude, and treatment practice (KAP) toward pediatric eye problems and to assess the effect of demographic factors such as gender, age, educational status, and number of children on KAP. Methods: A cross-sectional descriptive study was conducted in a hospital setting. Two hundred parents were randomly selected for the questionnaire. All parents had children who were included in Systematic Pediatric Eye Care Through Sibling Screening Strategies (SPECSSS) study. A survey with 15 questions on KAP of pediatric eye diseases was prepared and administered to parents coming to a tertiary eye hospital with varied experience and education qualifications. Results: The mean age of 200 patients was 9.6 (3.4) years, with the majority of them male (n = 110; 55.0%). The majority of the children (n = 91, 45.5%) were between the age group of 6-10 years. Knowledge of visual problems among parents was of a good grade in 9% only. The attitude of the parents toward the visual problem was positive at 17%, and the responses regarding the practice were of excellent grade at 46.5% and good at 26.5%. Analysis suggests that the level of knowledge and practice were not significantly associated with the demographic factors (p > 0.05). The positive attitude toward the visual problems of the children was associated with education of the parents (p < 0.05) and the father occupation (p < 0.05). Conclusion: Knowledge about pediatric eye diseases was poor among parents and it was significantly affected by education and occupation of parents. The parents have positive attitude toward enhancing their attitude in treatment.

Purpose: To study the refractive profile of children after they received intravitreal injection of bevacizumab for retinopathy of prematurity (ROP). Methods: The study was conducted at a tertiary eye care hospital in South India. ROP patients of more than 1 year of age, presenting to the Pediatric Ophthalmology Clinic and Retina Clinic and having history of treatment for type I ROP with intravitreal bevacizumab (IVB) or intravitreal bevacizumab and laser photocoagulation were included in the study. Cycloplegic refraction was done, and the refractive status was evaluated. The refractive status of age-matched, full-term children with uneventful perinatal and neonatal history was also recorded and compared to the study group. Results: Among 134 eyes of 67 study subjects, the major refractive error was myopia in 93 eyes (69.4%; spherical equivalent [SE] = -2.89 ± 3.1, range = -11.5 to -0.5 D). There were 75 eyes (56%) with low-to-moderate myopia; high myopia was seen in 13.4%, emmetropia in 18.7%, and hypermetropia in 11.9% of eyes. The majority of them (87%) had with-the-rule (WTR) astigmatism. In 134 eyes, the SE was -1.78 ± 3.2 (range = -11.5 to 4 D); the SE of the 75 eyes with low-to-moderate myopia was -1.53 ± 1.2 (range = -0.50 to -5 D). In the control group, the majority had emmetropia (91.8%). There was no significant association between the age at which IVB had been injected and the development of refractive errors (P = 0.078). The prevalence of low-to-moderate myopia was more than high myopia in patients with zone I and zone II ROP before treatment (60.0% and 54.5%, respectively). Conclusion: Myopia was the major refractive error seen in post-IVB pediatric patients. WTR astigmatism was more commonly seen. The age at which IVB injection had been given had no effect on the development of refractive errors.
