Contrast Sensitivity and Low Contrast Visual Acuity in Children With Normal Visual Acuity.

Purpose: To measure and report the distribution of distance and near contrast sensitivity (CS) and low contrast visual acuity (LCVA) at 5% and 2.5% contrast in children aged 5-15 years with normal visual acuity (VA).

Design: Prospective, cross-sectional study.

Refractive outcomes following silicone oil tamponade in vitreoretinal surgery.

Purpose: To evaluate the factors influencing the refractive outcomes following silicone oil tamponade (SOT) and silicone oil removal (SOR) in different lens statuses post-vitreoretinal surgery.

Design: Retrospective analysis of three different lens statuses.

Materials And Methods: This was a descriptive study that included 150 eyes of 147 patients who had undergone pars plana vitrectomy with SOT and SOR between January 2017 and June 2021.

mutations in Leber congenital amaurosis, early-onset severe retinal dystrophy, and retinitis pigmentosa from a tertiary eye care center in India.

Introduction: Mutations in the retinal pigment epithelial 65 kilodalton protein () gene are associated with various inherited retinal diseases (IRDs), including Leber congenital amaurosis (LCA), early-onset severe retinal dystrophy (EOSRD), and retinitis pigmentosa (RP). We screened for mutations in in a series of Indian patients with these IRDs to determine the frequency/types of mutations and to describe the associated phenotypes.

Materials And Methods: Diagnosis of LCA, EOSRD, and RP was made by standard and pre-defined criteria.

Low vision system for rapid near- and far-field magnification switching.

People suffering from low vision, a condition caused by a variety of eye-related diseases and/or disorders, find their ability to read greatly improved when text is magnified between 2 and 6 times. Assistive devices currently on the market are either geared towards reading text far away (~20 ft.) or very near (~2 ft.
