Abstract

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., Competing Interests: None

Abstract

Purpose: To evaluate the factors influencing final visual outcome after surgical repair of open globe injuries. Materials and Methods: The study was carried out at a tertiary referral eye care center in Central India. In this retrospective study, case records of 669 patients with open globe injuries were analyzed. Different preoperative variables were correlated with the final visual outcome. Exclusion criteria were patients with less than four months follow up, previous ocular surgery, presence of intraocular foreign body or endophthalmitis at the time of presentation. Using statistical tests, the prognostic factors for vision outcome following surgical repair of open globe injuries were studied. Results: Based on the Spearman's Rho correlation analysis, following factors were found to be significantly associated with the final visual acuity at univariate level: age (P

Abstract

There are few studies on pseudophakic monovision even though it is widely applied. We reviewed the published literature on pseudophakic monovision. Surgeons select patients who not only have a strong desire to be free of glasses after surgery, but also fully understand monovision design and its drawbacks. However, other criteria adopted for pseudophakic monovision are very different. Both traditional monovision and cross monovision are used in pseudophakic monovision, and the target binocular anisometropia ranges from -1.0 D to -2.75 D. Postoperative results were acceptable in every study and most patients were satisfied, with vision being improved and presbyopia corrected. Complications were decreased stereopsis, contrast sensitivity, and visual fields, similar to other types of monovision. The term "pseudophakic monovision" should include more than just monocular intraocular lens implantation in two eyes, and further studies are required.

Abstract

Aim : Eye morbidities with or without symptoms delineate a significant morbidity among adolescent schoolgirls in India. The study was undertaken to assess the extent of visual impairment and ocular morbidity to identify influencing factors and the impact on scholastic performance. Materials and Methods : A population-based cross-sectional study was undertaken among 3002 urban girl students of Surat in Gujarat, India. Overall prevalence of refractive error was found to be 15.22%; myopia affected 91.47%, hyperopia 4.60%, and astigmatism 0.04%. The prevalence of myopia and astigmatism was more in higher age groups, while hyperopia was more in lower age groups; even students with good vision reported ophthalmic symptoms. Of all spectacle users, in 29.73% cases the eyesight was not found to be with the best possible corrections. Refractive error was observed to be higher among the general caste (50.98%) and among Muslims (54.05%). Still, among those with problems of eyesight, 75.93% students had good academic performance. Associated ocular morbidity was noted in 20.35% participants along with the refractive error. Conclusion : This study highlighted the load of eye morbidities of adolescent Indian urban girls.
