PurposeAssess long-term outcome of combined trabeculotomy-trabeculectomy (CTT) in primary congenital glaucoma (PCG).MethodsData of PCG patients treated with CTT by a single surgeon between 1976 and 1993 were reviewed for reduction in intraocular pressure (IOP), visual acuities, surgical success rates, and need for repeat surgeries at last follow-up (FU). At the last FU, IOP<21 mm Hg without any topical antiglaucoma medication (TAM) was complete success and with 1-2 TAMs was qualified success. IOP reduction ≥30% without any TAM was modified complete success and with 1-2 TAMs was modified qualified success. IOP>21 mm Hg, IOP reduction <30%, or use of >2 TAM at last FU, or need for additional surgery was considered as failure.ResultsTwo hundred thirty eyes of 121 patients had been followed up for 21.5-38 years (mean 28.87±2.77 years). Eyes that were pthisical (3), had immeasurable IOP (2), or IOP<6 mm Hg (3) were excluded from the success analysis. At last FU, mean IOP reduction was 22.71±11.28 mm Hg and TAM score was 1.71 (0-4). Complete success was achieved in 14 (6.3%), modified complete success in 14 (6.3%), qualified success in 148 (66.7%), and modified qualified success in 140 (63.1%). Success probability was 95% till 25 years and 92, 90, 85, 79 and 68% at 26, 27, 28, 29, and 30 years, respectively. Severe visual impairment or functional blindness was found in only 13 (10.7%) patients.ConclusionCTT shows long-term success in PCG patients. All patients must be monitored for IOP control to avoid need for repeat surgeries.

Combined trabeculotomy-trabeculectomy showed promising results as a treatment for SWS-associated glaucoma in children. Long-term visual and surgical outcomes are encouraging.

There is a significant gap in the knowledge about glaucoma and its risks in both urban and rural set-ups in Northern India necessitating active steps to spread awareness regarding glaucoma and its relation with blindness.

Article InfoBackground: Uncontrolled hypertension and diabetes in truckers can negatively affect their work performance. This paper analyses the first-year data of an eye care program for truckers to assess their need for hypertension and diabetes screening. Materials and Method:In this cross-sectional study, data were collected via eye camps for truckers held between July 2017 and June 2018. Truckers who consented to have their blood pressure and glucose examined were included. Variables analysed included basic age profiles of the drivers attending the camps, the proportion of the truckers suffering from hypertension, the proportion with previously undetected hypertension, proportion of hypertensive drivers taking treatment and the proportion of the truckers with suspected diabetes. Z-test and Chi-square test were used for data analysis. Results: During the study period, 4,059 truckers attended camps, of whom 86.13% underwent hypertension screening. Out of those screened, 865 (24.7%, 95% CI: 23.31-26.17%) were diagnosed with hypertension. The mean age of the hypertensive drivers was higher than that of those with normal blood pressure (p < 0.001) and susceptibility to hypertension was found to increase with age. Among 816 drivers with hypertension who responded to questions about hypertension history, only 49.1% reported to have undergone blood pressure examinations earlier, while only 25.4% had received the treatment prescribed. The prevalence of high blood glucose was found to be 4% in the 3,433 drivers tested, which had an increasing trend with aging. Conclusions: There is an urgent need for formulating policies on hypertension screening and launching awareness campaigns in this mobile population.

Purpose: The purpose of this study was to assess the performance of the tertiary centers (TCS) and vision centers (VCs) of the four organizations participating in this research, once the lockdown was lifted, and to compare it with the performance during the same period of the previous year. Methods: This was a cross-sectional study assessing eyecare utilization in the first 2 months after resumption of services post the lockdown in 2020 and comparing that across the same time period in 2019. Anonymized data containing basic demographic details, proportions of patient visits and their reasons, as well as referral information was collected. The drop percentage method was used, and P values were calculated using paired t -tests. Results: Four TCs and 60 VCs were included. Overall, outpatient attendance dipped 51.2% at TCs and 27.5% at VCs, across the 2 years. At both levels of care delivery, the percentage drop in females was more than that in males; however, the overall drop at VCs was less than that at TCs, for both sexes. Eyecare utilization in pediatric populations dropped significantly more than in adult populations, across the overall sample. There was no significant change in referrals for refractive error as a proportion of total outpatients, although there was a significant decline in the same for cataract and specialty treatment. Conclusion: VCs are valuable and successful model for eyecare delivery especially in the continued aftermath of the COVID-19 pandemic.

Purpose: To compare the five-year incidence of acute post-operative endophthalmitis following cataract surgery, between centers with and without laminar air flow and high-efficiency particulate air (HEPA) filters in operating rooms. Methods: Retrospective analysis of medical records of patients operated in a single network of a tertiary and four secondary hospitals across north India. Cases of endophthalmitis were identified from the records between January 2013 and June 2018. Protocols and consumables were standardized across all hospitals. The only infrastructural difference being the presence of laminar air flow and high energy particulate air filters in operating rooms of the tertiary center. The type of surgery, along with the demographic and socio-economic details, were captured and analyzed, using z-test for proportions and logistic regression. Results: Out of 88,297 cataract surgeries conducted, 36 cases of endophthalmitis were reported. The incidence of endophthalmitis across the network was estimated to be 0.041%, (95% CI: 0.027 to 0.054). There was no statistically significant difference between the incidence of POE at the tertiary (0.042%) and secondary centers (0.039%). Certain risk factors for high endophthalmitis incidence were identified, namely patients undergoing small incision cataract surgery and belonging to lower socio-economic status. However, for both factors the difference was not statistically significant. Conclusion: The five-year incidence of acute post-operative endophthalmitis in our network was found comparable to the best reported in literature. Incidence at secondary centers, without laminar air flow and high energy particulate air filters was found comparable to that in the tertiary center having these facilities.

Purpose: Cataract remains the leading cause of blindness and visual impairment in most low-and middle-income countries, with the greatest burden borne by women. To achieve Global Action Plan targets, cataract programs must target people, especially women, with maximum need. This study examines whether cataract surgical programs in three major north Indian eyecare institutions are equitable and describes a refined indicator for reporting equity. Methods: Retrospective one-year cross-sectional study of cataract surgery utilization using routine administrative data from three north Indian eyecare institutions. Patient data were categorized by paying category, sex, and preoperative visual acuity. Comparisons were made between payment categories and sexes. Results: Out of the total number of patients operated, 86,230 were in the non-paying category and 56,738 in the paying category. Overall, 8.2% were blind, 21.1% were severely visual impaired (SVI) or worse, and 86.1% were moderate visual impaired (MVI) or worse. Non-paying patients had a significantly higher proportion of poorer visual categories compared to paying patients [(blind, 9.7% vs. 5.8%; SVI or worse, 24.6% vs. 15.8%; and MVI or worse, 89.1% vs. 81.6%, respectively, ( P < 0.001)]. Women had significantly higher proportion of poorer visual categories than men [(blind, 8.9% vs. 7.4%, SVI or worse, 21.9% vs. 20.3% and MVI or worse 87.6 vs. 84.7%) ( P < 0.001)]. Conclusion: The institutions primarily provided surgery to patients with maximum need: too poor to pay, low visual acuity, and women. Similar data from all service providers of a region can help estimate the proposed “equitable cataract surgical rate”: the proportion of patients operated with maximum need among those operated in a year. This can be used for targeting people in need.
