RESUMO
PURPOSE: To report the trends in the clinical presentation, diagnosis, and management of keratoconus (KC) in patients presenting to a multitier hospital network over 33 years. METHODS: This retrospective study included patients with KC presenting from 1987 to 2020. Patients with KC in at least 1 eye were included. The data of 20,576 patients included in this study were retrieved from the electronic medical record database. Data on patient demographics, ocular diagnosis, contact lens usage, and surgical history were collected and exported for analysis. Descriptive statistics and chi square test were used for statistical analysis. RESULTS: A total of 20,576 KC cases were seen from 1987 to 2020. Mean age at diagnosis reduced from 29.3 years (1987-1991) to 22.2 years (2016-2020). Adults (76.64%) were commonly affected with a majority being male (61.25%). Use of contact lenses increased from 4.34% (2002-2006) to 11.23% (2016-2020). Of the total number of surgical interventions, collagen crosslinking (CXL) constituted more than 1/5th (22.28%) between 2007 and 2011, which increased to more than half between 2012 and 2016 (53.61%) and almost 3/4th (72.53%) between 2017 and 2020. Advances in lamellar surgery have led to more patients undergoing deep anterior lamellar keratoplasty (DALK) as compared with penetrating keratoplasty. In the last 8 years, 17.2% patients underwent surgery and the most common was CXL (14.77%) followed by DALK (1.72%) and penetrating keratoplasty (1.04%). CONCLUSIONS: We report the trends in the clinical presentation and management of KC over 3 decades. In the last 33 years, advances in diagnostics have helped diagnose KC earlier. Contact lenses and advances in CXL have reduced the number of keratoplasties in KC, DALK being more common.
RESUMO
INTRODUCTION: To describe the clinical profile, complications and trends of ocular anaesthesia in a multi-tier ophthalmology network in India. METHODS: This retrospective hospital-based study included 417,622 patients presenting between January 2013 and December 2020. Patients who were administered either topical, local or general anaesthesia for ocular surgery in at least one eye were included as cases. The data were collected using an electronic medical record system. RESULTS: Among the 417,622 patients, local anaesthesia was administered to 280,638, (67.2%) patients and was the most commonly administered type followed by topical anaesthesia in 84,117 (20.14%) patients. The most common complication encountered in administering local anaesthesia was retrobulbar haemorrhage in 103 (0.037%) patients followed by lid haematoma in 49 (0.017%) patients. Tooth damage occurred in 40 (0.076%) patients followed by delayed recovery in 30 (0.057%) patients during general anaesthesia. The trend of local anaesthesia decreased (83.48% vs 53.36%), whereas the trend of topical anaesthesia increased (8.61% vs 32.42%) over the study period. CONCLUSION: There is a notable trend towards the adoption of less invasive anaesthetic methods, particularly in common surgeries such as cataract, intravitreal injection, and vitreoretinal surgery. However, despite this trend, a significant proportion of oculoplastic/orbital surgeries, trauma, and strabismus surgeries continue to be performed under general anaesthesia. These observations underscore the ongoing evolution of ocular anaesthesia practices, reflecting advancements in surgical techniques and patient preferences.
RESUMO
Purpose: To determine macular pigment (MP) density scores in healthy Indians and examine correlations with demographic and lifestyle variables. Methods: We observed 484 Indians without an ocular pathology. Body mass index (BMI) and self-reported lifestyle factors (sunglasses usage, physical activity, and smoking) were noted. MP density was assessed as the threshold of perception of the shadow of their macular pigments on their retina using a new MP assessment tool (MP-eye). Lutein and zeaxanthin intake was assessed using a prevalidated questionnaire regionally designed for the Indian diet. Clusters of participants were created for statistical analysis based on MP-eye scores secondarily to detect any relevant effects in very low, low, medium, and high ranges of MPs. Results: Data analyzed included 235 males and 249 females with mean age of 36.1 ± 12.9 years (range, 14-72). The median MP-eye score was 6 (range, 0-10, with 10 being high). Most were non-smokers (413, 85.3%) and did not use sunglasses (438, 90.5%), and 314 (64.9%) had low physical activity. Diabetes was present in 62 participants (12.8%) and hypertension in 53 (10.9%). Advancing age (r = -0.209; P < 0.000) and BMI (r = -0.094; P = 0.038) had weak negative correlation with MP-eye scores. Hypertension was less prevalent (7/88) in the cluster with the highest median MP-eye score (P = 0.033). Dietary intake of MPs and other lifestyle factors did not correlate significantly with MP-eye score overall or when analyzed in clusters. Conclusions: MP-eye scores of an Indian population were normally distributed. Higher age, high BMI, and presence of hypertension were weakly associated with lower MP-eye scores. The impact of diet on MPs requires further evaluation. Translational Relevance: This normative regional database enables risk stratification of macular degeneration.

OBJECTIVE: To describe the demographics, clinical, and imaging characteristics, and visual outcomes in young patients with full-thickness traumatic macular hole (TMH). METHODS: This retrospective hospital-based study included patients with full-thickness TMH who presented between August 2010 and June 2021. Demographic data, clinical findings, and imaging characteristics were extracted from an electronic medical record system. Regression analyses were performed to determine significant associations among variables and to identify predictors of visual outcomes. RESULTS: 144 (0.005%) patients among 2,834,616 were diagnosed with Full thickness TMH. The majority of them were male (89.58%; odds ratio [OR] = 6.71) and the holes were unilateral. The mean age at presentation was 23.37 ± 8.19 years. Ball were the most common cause of injuries (22.22%), followed by stick (14.58%) and firecracker (12.50%). The mean LogMAR visual acuity (VA) at presentation was 1.18 ± 0.72, with 25.69% of eyes having VA < 20/400. The mean minimum hole diameter was 619.34 ± 336.16 µm. Sub-retinal fluid was present in 44.44%, followed by intraretinal fluid in 34.03% of eyes. Macular holes closed after vitrectomy in 66.67% of eyes, with mean final VA of 1.07 ± 0.85. Baseline VA was a strong predictor of final VA (R2 = 0.677; p = 0.000168). CONCLUSION: Traumatic macular hole is a unilateral condition with significant visual impairment that is mainly seen in males during the third decade of life. Surgery is successful in most cases but improvements in VA are modest.
RESUMO
PURPOSE: To study the epidemiology and microbiological landscape in patients (≤21 yrs) diagnosed with endophthalmitis across a multi-tier ophthalmology network in India. METHODS: This cross-sectional hospital-based study included 1,041 patients (≤21 yrs) diagnosed with endophthalmitis, between April 2012 and May 2022. The data were collected using an electronic medical record system. RESULTS: Bacteria (24%) was the most common etiology followed by fungus (2%). The majority of the patients were male (66%) with a mean age of 8.37 ± 5.99 years. The most common age group was middle childhood (6-11 years) with 365 (35.06%) patients. The patients were more commonly from the lower socio-economic status (60.81%) and urban geography (49%). The common cause of endophthalmitis was trauma (59.33%) and amongst the 279 culture positive eyes, the predominant bacteria isolated was Streptococcus pneumoniae followed by Bacillus species and fungus included predominantly Aspergillus and Candida species. The most common surgical intervention performed was intraocular antibiotics (74%) followed by pars plana vitrectomy (52%). CONCLUSION: The most common etiology of endophthalmitis in children is bacterial and traumatic in nature and presented from the lower socio-economic status. A half of the eyes warranted a vitreo-retinal surgical intervention. .
A cross-sectional study on the microbiological landscape in pediatric endophthalmitis showed that the most common cause of endophthalmitis was trauma and the predominant bacteria isolated was Streptococcus spp. and Bacillus spp. Additionally, majority of the patients were from the lower socio-economic status and urban geography and the most common surgical intervention performed was injection of intraocular antibiotics.

PURPOSE: To report the clinical settings, management, and factors associated with outcomes of rhegmatogenous retinal detachment with concurrent choroidal detachment. METHODS: Retrospective, consecutive, multicenter case series from January 2014 to January 2021 were included. Cases were from a tertiary eye care center in India and Taiwan. RESULTS: Overall 303 eyes were included. Mean age was 43.72 ± 20.64 years (median 46). Best-corrected presenting visual acuity was 1.79 ± 0.92 logMAR (median 2.10) (Snellen 20/1,233). Forty-four patients (17.91%) received preoperative steroids. Final visual acuity was 1.33 ± 0.94 logMAR (median 1.10) (Snellen 20/427). Favorable anatomic outcome was seen in 200/303 (66%), whereas favorable functional outcome was seen in 128/303 (42.20%). Factors predicting favorable anatomic outcome were absence of phakic lens status (odds ratio [OR] 2.76), absence of proliferative vitreoretinopathy worse than Grade A (OR 7.69), use of preoperative steroids (OR 4.50), and use of an encircling band (3.85). Factors predicting favorable functional outcome were better presenting visual acuity (OR 3.03), absence of phakic lens status (OR 4.93), absence of proliferative vitreoretinopathy worse than Grade A (OR 10.41), and use of preoperative steroids (OR 7.24). CONCLUSION: Administration of preoperative steroids, use of an encircling band during surgery, and pseudophakic status of the eye were found to have better outcomes in rhegmatogenous retinal detachment with concurrent choroidal detachment.

Purpose: To describe the clinical profile and relative prevalence of subtypes of glaucoma presenting to a tertiary care center in India. Methods: This cross-sectional hospital-based study included 6,120 new patients (>16 years) presenting between January 2016 and December 2017. The data were collected using an electronic medical record system. Results: A total of 11,016 eyes of 6,120 new patients were diagnosed with glaucoma. Sixty-one percent were male and 79% had a bilateral affliction. Primary glaucoma was present in 4,352 (71.1%) and secondary glaucoma in 1,063 (17.4%) subjects. Glaucoma was primary open-angle (POAG) in 4,015 (36.4%) eyes and primary angle closure disease (PACD) in 3,806 (34.5%) eyes. Commonest among secondary glaucoma was post-cataract surgery glaucoma (3.1%), neovascular glaucoma (2.4%), pseudoexfoliation glaucoma (PXG) (2.1%), and steroid-induced glaucoma (SIG) (1.4%). Patients with primary glaucoma were older than secondary (56.6 ± 0.2 vs 54.1 ± 0.4; P < 0.0001). Mean IOP was higher in secondary glaucoma compared to primary (26.9 ± 0.3 vs 18.9 ± 0.1; P < 0.0001). Secondary glaucoma had greater mean CDR compared to primary glaucoma (0.77 ± 0.007 vs 0.70 ± 0.003; P < 0.0001). The prevalence of blindness (visual acuity <20/200) was 16.2% of eyes. Mean deviation (MD) 20db or worse was noted in 39.5% of eyes at presentation including 47.8% of PACG, 37.3% of POAG, 51% of JOAG, 58% of PXG, and 45% of SIG, suggesting disease severity. Conclusion: At the presentation to a tertiary care center, 40% of all eyes with glaucoma had advanced disease with MD worse than - 20D. PACG and JOAG had the worse disease among primary; among secondary, PXG and SIG had the worse disease at presentation.

Purpose: To report a big data analysis of risk and protective factors in patients with AMD, as well as report on the age-adjusted prevalence in a geriatric Indian cohort in a hospital setting. Methods: This retrospective, observational study of all patients older than 60 years of age. Multiple logistic regression was performed for the binary outcome and the presence of AMD. Variables analyzed include age, gender, socioeconomic status, occupation, urban-rural-metropolitan distribution, self-reported history of diabetes mellitus (DM), hypertension (HTN), or coronary artery disease (CAD), ocular comorbidities, history of cataract surgery, and presenting VA. Odds ratios (OR) and 99% confidence intervals were calculated. Results: Of the 608,171 patients over the age of 60 years who attended our clinics, 1.68% of subjects had a diagnosis of AMD (N = 10,217). Less than half (4,621 of 10,217 with AMD) of them were diagnosed to have dry AMD. Cataract, glaucoma, and diabetic retinopathy were associated with lower risk of AMD. Cataract surgery was associated with the higher risk of AMD (OR = 1.20; 99% CI 1.13-1.29). Smoking was not associated with AMD. Conclusion: Big data analysis from a hospital setting shows that the prevalence of AMD above the age of 60 years is low. More patients with wet AMD present for treatment compared to dry AMD. Smoking was not associated with AMD in the Indian population. Cataract surgery was associated with higher prevalence of AMD.

Purpose: To describe the demographics and clinical profile of Stargardt disease in patients presenting a multitier ophthalmology hospital network in India. Methods: This cross-sectional hospital-based study was performed among 2,834,616 new patients presenting between August 2010 and June 2021 in our network. Patients with a clinical diagnosis of Stargardt disease in at least one eye were included as cases. The data were collected using an electronic medical record system. Results: Overall, 1,934 (0.069%) patients were diagnosed with Stargardt disease. Most of the patients were male (63.14%). The most common age group at presentation was during the second decade of life, with 626 (31.87%) patients. The overall prevalence was higher in patients from a higher socioeconomic status (0.077%), in those presenting from the urban geography (0.079%), and in students (0.197%). Systemic history of hypertension was seen in 56 (2.85%) patients, while diabetes mellitus was seen in (2.49%) patients. Of the 3,917 eyes, 1,910 (48.76%) eyes had moderate visual impairment (>20/70-20/200) followed by severe visual impairment (>20/200 to 20/400) in 646 (16.49%) eyes. The most commonly associated retinal signs were retinal flecks in 1,260 (32.17%) eyes, followed by RPE changes in 945 (24.13%) eyes. The most documented investigations were autofluorescence (39.85%), followed by optical coherence tomography (23.90). Cataract surgery was the commonest performed surgical intervention in (0.66%) eyes, followed by intravitreal injection in 4 (0.10%) eyes. The family history of parent consanguinity marriage was reported by 212 (10.79%) patients. Conclusion: Stargardt disease was seen more commonly in males presenting during the second decade of life. It is predominantly a bilateral disease, with the majority of the eyes having moderate visual impairment.

Purpose: To study and compare the demographic and clinical profile of acute ocular burns (AOB) in children and adults. Methods: This retrospective case series included 271 children (338 eyes) and 1300 adults (1809 eyes) who presented to two tertiary eye care centers within one month of sustaining AOB. Data regarding demographics, causative agents, severity of injury, visual acuity (VA), and treatment were collected and analyzed. Results: Males were more commonly affected particularly among adults (81% versus 64%, P < 0.00001). Among children, 79% sustained domestic injuries, whereas 59% of adults had work-place injuries (P < 0.0001). Most cases were due to alkali (38%) and acids (22%). Edible lime (chuna, 32%), superglue (14%), and firecrackers (12%) in children, and chuna (7%), insecticides, lye, superglue (6% each), toilet cleaner (4%) and battery acid (3%) in adults, were the main causative agents. The percentage of cases with Dua grade IV-VI was greater in children (16% versus 9%; P = 0.0001). Amniotic membrane grafting and/or tarsorrhaphy were needed in 36% and 14% of affected eyes in children and adults, respectively (P < 0.00001). The median presenting VA was logMAR 0.5 in children and logMAR 0.3 in adults (P = 0.0001), which improved significantly with treatment in both groups (P < 0.0001), but the final VA in eyes with Dua grade IV-VI burns was poorer in children (logMAR 1.3 versus logMAR 0.8, P = 0.04). Conclusion: The findings clearly delineate the at-risk groups, causative agents, clinical severity, and treatment outcomes of AOB. Increased awareness and data-driven targeted preventive strategies are needed to reduce the avoidable ocular morbidity in AOB.

Purpose: To describe the demographics and clinical profile of pseudoexfoliation syndrome (PXF or PES) in patients presenting to a multi-tier ophthalmology hospital network in India. Methods: This cross-sectional hospital-based study included 3,082,727 new patients presenting between August 2010 and December 2021. Patients with a clinical diagnosis of PXF in at least one eye were included as cases. The data were collected using an electronic medical record system. Results: Overall, 23,223 (0.75%) patients were diagnosed with PXF. The majority of the patients were male (67.08%) and had unilateral (60.96%) affliction. The most common age group at presentation was during the seventh decade of life with 9,495 (40.89%) patients. The overall prevalence was higher in patients from a lower socio-economic status (1.48%) presenting from the urban geography (0.84%) and in retired individuals (3.61%). The most common location of the PXF material was the pupillary margin (81.01%) followed by the iris (19.15%). The majority of the eyes had mild or no visual impairment (<20/70) in 12,962 (40.14%) eyes. PXF glaucoma was documented in 7,954 (24.63%) eyes. Krukenberg's spindle was found in 64 (0.20%) eyes, phacodonesis in 328 (1.02%) eyes, and lens subluxation in 299 (0.93%) eyes. Among the surgical interventions, cataract surgery was performed in 8,363 (25.9%) eyes, trabeculectomy was performed in 966 (2.99%) eyes, and a combined procedure in 822 (2.55%) eyes. Conclusion: PXF more commonly affects males presenting during the seventh decade of life from lower socio-economic status and is predominantly unilateral. A quarter of the affected eyes are associated with glaucoma and the majority of the eyes have mild or no visual impairment.

Purpose: The current study was carried out to evaluate the clinical features and management outcomes of dry eye disease (DED) in chronic ocular GvHD following allogenic hematopoietic stem cell transplantation (HSCT). Methods: A retrospective review of consecutive patients diagnosed with chronic ocular GvHD between 2011 and 2020 was performed at a tertiary eye care network. Multi-variate regression analysis was carried out for identifying risk factors associated with progressive disease. Results: A total of 34 patients (68 eyes) with a median age of 33 years [inter-quartile range (IQR) 23-40.5] were studied. The most common indication for HSCT was acute lymphocytic leukemia (26%). Ocular GvHD developed at a median of 2 years (IQR 1-5.5 years) after HSCT. Aqueous tear deficiency was present in 71% of the eyes, of which 84% had a Schirmer value of <5 mm. The median visual acuity at presentation and that after a median follow-up of 6.9 months were comparable at 0.1 log minimum angle of resolution (logMAR) (P = 0.97). Topical immunosuppression was required in 88% of cases, and with this, improvement in corneal (53%, P = 0.003) and conjunctival staining scores (45%, P = 0.43) was noted. A progressive disease was present in 32% with persistent epithelial defects being the most common complication. Grade 2 conjunctival hyperemia [odds ratio (OR): 2.6; P = 0.01] and Schirmer's value <5 mm (OR: 2.7; P = 0.03) were found to be associated with progressive disease. Conclusion: Aqueous deficient DED is the most common ocular manifestation of chronic ocular GvHD, and the risk of the disease progression is greater in eyes with conjunctival hyperemia and severe aqueous deficiency. Awareness among ophthalmologists of this entity is essential for its timely detection and optimal management.

PURPOSE: To describe the spectrum and demographic distribution of non-oncological retinal diseases in children and adolescents presenting to a multi-tier ophthalmic hospital network in India. METHODS: This is a cross-sectional hospital-based retrospective study over nine years (March 2011-March 2020) from a pyramidal eye care network in India. The analysis included 477,954 new patients (0-21 years), collected from an International Classification of Diseases (ICD) coded electronic medical record (EMR) system. Patients with a clinical diagnosis of retinal disease (non-oncological) in at least one eye were included. Age-wise distribution of these diseases in children and adolescents was analysed. RESULTS: In the study, 8.44% (n = 40,341) of new patients were diagnosed with non-oncological retinal pathology in at least one eye. The age group-specific distribution of retinal diseases was 47.4%, 11. 8%, 5.9%, 5.9%, 6.4%, 7.6% in infants (< 1 year), toddlers (1-2 years), early childhood (3-5 years), middle childhood (6-11 years), early adolescents (12-18 years) and late adolescents (18-21 years), respectively. 60% were male, and 70% had bilateral disease. The mean age was 9.46 ± 7.52 years. The common retinal disorders were retinopathy of prematurity (ROP, 30.5%), retinal dystrophy (19.5%; most commonly, retinitis pigmentosa), and retinal detachment (16.4%). Four-fifth of the eyes had moderate to severe visual impairment. Nearly one-sixth of patients needed low vision and rehabilitative services, and about 1 in 10 patients required surgical intervention (n = 5960, 8.6%). CONCLUSION AND RELEVANCE: About 1 in 10 children and adolescents seeking eye care in our cohort had non-oncological retinal diseases; the common ones were ROP (in infants) and retinitis pigmentosa (in adolescents). This information would help future strategic planning of eye health care in the institution in pediatric and adolescent age groups.

Purpose: To describe the demographics, clinical profile, and outcomes of ocular siderosis in patients presenting to a multi-tier ophthalmology hospital network in India. Methods: This cross-sectional and hospital-based study included 3,082,727 new patients who presented between August 2010 and December 2021. Patients with a clinical diagnosis of ocular siderosis in at least one eye were included. Results: Overall, 58 eyes of 57 patients (0.002%) were diagnosed with ocular siderosis. The majority were men (96.49%) and had unilateral (98.25%) affliction. The most common age group at presentation was during the third decade of life with 24 patients (42.11%). A clear history of ocular trauma was documented in 47 patients (81.03%). Major clinical signs included corneal pigment deposition in nearly half of the eyes (27/58 eyes, 46.55%), corneal scar (20/58 eyes, 34.48%), cataract (22/58 eyes, 37.93%) and retinal detachment (11/58 eyes, 18.96%). The intraocular foreign body (IOFB) was anatomically localized in a majority of the eyes (i.e., 45/58 eyes, 77.59%). The most common location of the IOFB was in the posterior segment (22/58 eyes, 37.93%). The eyes that underwent a vitreoretinal surgery with removal of IOFB had a slightly better BCVA (1.0 ± 1.01) when compared to eyes with non-removal of IOFB (1.58 ± 1.00). Conclusion: Ocular siderosis is a rare sight-threatening entity, with half of the affected eyes exhibiting severe visual impairment. Majority of the eyes in ocular siderosis will have a detectable IOFB. Surgical removal of IOFB may lead to a better visual gain when compared to non-removal.

PURPOSE: To study etiology, clinical presentation, anatomical, and functional outcomes of patients with giant retinal tear detachment at a tertiary eye institute. METHODS: Retrospective, consecutive case series of 396 patients (396 eyes) who underwent surgery were reviewed. Factors affecting the final anatomical and functional success were determined. RESULTS: Mean age was 37 years (range; 1-79 years), and 86% (n = 339) of the subjects were men. Trauma (21%) and high myopia (11%) were predisposing risk factors. Two hundred and seventy-seven eyes (70%) had giant retinal tear configuration of >180° and <270°, associated with partial retinal detachment in 282 (71%) eyes and macular detachment in 262 (66%) eyes. Primary surgery included pars plana vitrectomy (n = 240, 61%), pars plana vitrectomy with encirclage band (n = 152, 38%), or scleral buckle (n = 4, 1%). The mean follow-up duration was 15 months (median, 8.4 months; range, 3-83 months). Anatomical success after initial surgery was 64% (255 eyes), which improved to 78% (308 eyes) after undergoing a second vitreoretinal procedure for recurrent retinal detachment (53 eyes). Median visual acuity improved from 20/1,500 preoperatively to 20/400 at final follow-up ( P = 0.01), and 15% of eyes achieved postoperative visual acuity of 20/60 or better. Factors associated with poor anatomical success included age <16 years ( P = 0.005) and presenting visual acuity 20/400 or less ( P = 0.001). CONCLUSION: Trauma and myopia constituted the major risk factors for giant retinal tear detachment in our series. Surgery for giant retinal tear detachment managed with pars plana vitrectomy with or without encirclage band and silicone oil tamponade had good anatomical and favorable visual outcomes at last follow-up.

OBJECTIVE: To study the clinical presentation and treatment outcomes of patients with vasoproliferative retinal tumor (VPRT) in India. METHODS: Retrospective study of 50 eyes in 47 patients. RESULTS: Of the 50 eyes, 25 (50%) were primary and 25 (50%) were secondary. Common ocular pathologies related to secondary VPRT included retinal detachment (n = 8, 32%) and Coats disease (n = 7, 28%). Overall, the mean age at presentation was 35 years (range; 3-74 years) and included 30 (64%) males and 17 (36%) females. The lesions were unilateral in 44 (94%) patients. Secondary retinal features included intra/subretinal exudation (n = 41, 82%), vascularity (n = 32, 64%), subretinal fluid (n = 21, 42%), retinal neovascularisation (n = 9, 18%) and vitreous hemorrhage (n = 8, 16%). Thirty-four eyes (68%) underwent cryotherapy, of which 16 eyes (47%) received adjunct intravitreal anti-VEGF (12 eyes) or corticosteroid injection (4 eyes). Primary surgery included vitrectomy with/without encirclage and cryotherapy (n = 12, 24%) and plaque brachytherapy (n = 3, 6%). At last follow-up (mean 9.7 months, range 3-67 months), 42 eyes (84%) had complete tumor regression with no improvement in visual outcomes when comparing presenting and final best corrected visual acuity. Comparing primary versus secondary VPRT, secondary VPRT presented a decade earlier (31 vs 40 years), needed surgical intervention (48% vs 20%), had poor tumor control (72% vs 92%) and worse visual outcomes (p < 0.05). CONCLUSION: VPRTs commonly present as a unilateral lesions in the adult population with equal prevalence of primary and secondary variants. Compared with primary VPRT, secondary VPRTs require surgical treatment and are associated with poor visual outcome.

OBJECTIVE: To study the epidemiology and landscape of ocular infections in patients undergoing microbiological investigations across a multi-tier ophthalmology network in India. METHODS: This cross-sectional hospital-based study included 15,822 patients in whom microbiology samples were analysed between September 2013 and December 2021. Ocular tissue of patients in whom a microbiology sample was processed in at least one eye were included. The data were collected using an indigenously developed electronic medical record system. RESULTS: Among the 15,822 patients, bacteria (51.06%) was the most common aetiology followed by fungus (38.27%). The majority of the patients were male (68.10%) and adults (90.01%). The most common age group was during the sixth decade of life with 2,914 (18.42%) patients. The patients were more commonly from the lower socio-economic status (51.61%) and from the rural geography (46.82%). Majority of the specimens sent for microbiological analysis were corneal scrapings (68.61%) followed by vitreous (8.77%). The most common bacteria isolated was Staphylococcus aureus (14.45%) followed by Pseudomonas aeruginosa (12.53%) and among the fungus were Fusarium (30.53%) and Aspergillus species (29.86%). Acanthamoeba (1.26%) and Microsporidia (0.38%) accounted for a minority of the infections in the samples. Fungus (53.10%; p ≤ 0.00001) and virus (51.08%; p = 0.000673) aetiology was found to be significantly higher in patients presenting from the rural geography. CONCLUSION: The most common aetiology of infection in ocular disease is bacterial but fungal infections also accounted for a significant proportion. The majority of the patients with ocular infections presented from the rural geography and from lower socio-economic status.

PURPOSE: To describe the demography, clinical settings and outcomes in 2071 patients undergoing evisceration across a multi-tier ophthalmology hospital network and comparison of results with the global scenario of clinical settings for evisceration. METHODS: An analysis of 2071 patients undergoing evisceration and implant between 2013 and 2019. RESULTS: The mean age at surgery was 39 ± 22 years. Children constituted 303(15%) of the cases. The four leading indications for surgery included painful blind eye in 760(37%), phthisis bulbi in 552(27%), staphyloma in 215(10%) and open globe injury in 195(9%) patients. The clinical settings encountered were trauma in 852(41%), ocular infection in 714(34%), glaucoma in 198(10%), post ocular surgery in 146(7%), congenital in 95(5%) and uveitis in 21(1%). Trauma and infection remained the commonest clinical settings in the urban (843,75%), rural (622,77%) and metropolitan (101,71%) areas. Decade wise distribution suggested trauma to be the commonest clinical setting in the first 4 decades and infection in the next 6 decades. The mean follow-up period was 351 ± 386 days (median 194). While trauma remained one of the commonest clinical setting in both the developed and the developing economies, painful blind eye and intractable glaucoma were other common clinical settings in the developed economies and infection was one of the leading clinical setting in the developing economies. CONCLUSION: Most patients undergoing evisceration are young. The commonest indications for surgery include painful blind eye and phthisis bulbi. Trauma and infection remain the commonest clinical settings for evisceration in developed and developing economies.

Introduction. Injudicious use of antibiotics often leads to antibiotic resistance which contributes to significant morbidity and mortality. Knowledge of local antibiogram is important in informing appropriate empiric antimicrobial therapy.Hypothesis / Gap. It is the first and largest study that examines bacterial isolates from multiple ocular infections across South India and provides a overview of susceptibility patterns for each individual bacteria in the detailed interactive dashboard.Aim. To study the landscape of bacterial antibiotic susceptibility patterns of ocular infections in patients undergoing microbiological investigations across a multi-tier ophthalmology network in India.Methodology. This cross-sectional hospital-based study included 15â822 patients in whom microbiology samples were analysed between September 2013 and December 2021. Ocular tissue of patients in whom a microbiology sample was processed in at least one eye were included as cases. The data were collected using an indigenously developed electronic medical record (EMR) system.Results. Among the 15â822 patients, bacteria (51.06â%) was the most common aetiology, followed by fungus (38.27â%). The majority of the patients were male (68.10â%) and the majority were adults (90.01â%). The most common age group was during the sixth decade with 2914 (18.42â%) patients. The patients were more commonly from the lower socio-economic status (51.61â%) and rural geography (46.82â%). The majority of the specimens sent for microbiological analysis were corneal scraping (68.61â%). Gram-positive cocci and Gram-positive bacilli were most sensitive towards vancomycin (86.83 and 92.89% respectively) followed by cefazolin (80.88â%) and amikacin, while Gram-negative bacilli were most sensitive towards ofloxacin (65.24%).Conclusion. The most common aetiology of infection in ocular disease is bacterial and the majority of the patients presented from the rural geography and from lower socio-economic status. While vancomycin continues to be the drug of choice for Gram-positive organisms, increasing resistance to fluoroquinolones and ceftazidime was observed. Adoption of this model will enable access to antimicrobial susceptibility data, leading to reliable decisions and better clinical outcomes.

Purpose: The aim of this study was to develop a risk stratification system that predicts visual outcomes (uncorrected corrected visual acuity at one week and five weeks postoperative) in patients undergoing cataract surgery. Methods: This was a retrospective analysis in a multitier ophthalmology network. Data from all patients who underwent phacoemulsification or manual small-incision cataract surgery between January 2018 and December 2019 were retrieved from an electronic medical record system. There were 122,911 records; 114,172 (92.9%) had complete data included. Logistic regression analyzed unsatisfactory postoperative outcomes using a main effects model only. The final model was cross-checked using forward stepwise selection. The Hosmer-Lemeshow goodness of fit test, the Bayesian information criterion, and Nagelkerke's R2 assessed model fit. Dispersion was calculated from deviance and degrees of freedom and C-stat from receiving operating characteristics analysis. Results: The final phacoemulsification model (n = 48,169) had a dispersion of 1.08 with a Hosmer-Lemeshow goodness of fit of 0.20, a Nagelkerke R2 of 0.19, and a C-stat of 0.72. The final manual small-incision cataract surgery model (n = 66,003) had a dispersion of 1.05 with a Hosmer-Lemeshow goodness of fit of 0.00015, a Nagelkerke R2 of 0.14, and a C-stat of 0.68. Conclusion: The phacoemulsification model had reasonable model fit; the manual small-incision cataract surgery model had poor fit and was likely missing variables. The predictive capability of these models based on a large, real-world cataract surgical dataset was suboptimal to determine which patients could benefit most from sight-restoring surgery. Appropriate patient selection for cataract surgery in developing settings should still rely on clinician thought processes, intuition, and experience, with more complex cases allocated to more experienced surgeons.
