Aim And Background: The study aims to determine the accuracy of utilizing a temporal view in the detection of a shallow anterior chamber (AC), in comparison to the conventional anterior view, by evaluation of photographs of the anterior segment of the eye.

Materials And Methods: Two hundred fifty students who had completed basic undergraduate ophthalmology training as part of their medical education graded the AC depth in anterior segment photographs as "shallow" or "not shallow." Each eye was photographed from the anterior and temporal views.

The demand for treating diseases using yoga therapy, a Complementary and Alternative Medicine (CAM) treatment, has increased globally. An increase in the research in this yoga area from fewer than 10 research publications per year in the 1990s to at least 20 per year after 2010 is evidence of this change in treatment needs over time. The beneficial effect of yoga therapy has been limited to practice in acute care despite its remarkable success in this domain.

Article Synopsis
  • Refractive error is a significant cause of visual impairment in children, and early detection using the modified Brückner test can prevent conditions like amblyopia and strabismus.
  • In a study involving 683 children aged 4 to 10, the characteristics of the red reflex were analyzed with a direct ophthalmoscope, showing a strong correlation between the presence of crescents in the reflex and types of refractive errors (hypermetropia and myopia).
  • The modified Brückner test proved to be a quick and effective method for screening refractive errors in children, with high sensitivity, making it suitable for community health settings.

Article Synopsis
  • The study reports a rare case of unilateral acute hypertensive uveitis occurring alongside systemic leptospirosis in a young male patient from coastal Karnataka, India.
  • The patient, who was experiencing an acute febrile illness, was found to have elevated intraocular pressure and anterior uveitis in one eye.
  • The uveitis improved with medical treatment, highlighting the need to include leptospirosis as a potential diagnosis in similar eye conditions.

Article Synopsis
  • Chákṣu is a retinal fundus image database designed to help evaluate computer-assisted techniques for glaucoma prescreening, containing 1,345 color images from various fundus cameras.
  • Each image includes outlines for the optic disc and optic cup, alongside assessments of whether the images show normal or glaucomatous conditions, made by five expert ophthalmologists.
  • The database is the largest of its kind focusing on Indian ethnicity, providing detailed expert annotations and ground truths, which will be useful for advancing artificial intelligence in glaucoma diagnostics.

We report the occurrence of unilateral central retinal vein occlusion (CRVO) in a young yoga enthusiast who presented amidst the COVID-19 pandemic. Subtle signs of uveitis when systemically investigated revealed a multitude of causes, but ocular fluid polymerase chain reaction was positive for varicella zoster virus (VZV). The prompt initiation of antivirals resulted in a good visual outcome.

Purpose: The purpose of the study was to study the association between diabetic retinopathy (DR) and periodontal disease (PD) in a South Indian cohort.

Methods: This was a cross-sectional, observational, interdisciplinary hospital-based study wherein patients with diabetes mellitus visiting the ophthalmology department of a university teaching hospital in coastal Karnataka, south India, during the study period, were screened independently for retinopathy by an ophthalmologist and PD by a periodontal surgeon. All the patients were above 18 years of age and did not have juvenile or gestational diabetes.

Purpose: This study aimed to explore the role of smartphone imaging of the eye using two perspectives - anterior and temporal - in the detection of a shallow anterior chamber (AC). The AC depth (ACD) of an eye can be used as a surrogate marker for identification of eyes at risk of developing angle-closure disease.

Methods: A prospective observational study was conducted at a university teaching hospital in South India.

We report a case of a young male from Udupi, Karnataka, presenting with features of bilateral non-granulomatous anterior uveitis with mild vitritis. There was a history of fever and myalgia a month before ocular features, which was partially treated. He also gave a history of being actively involved in the flood relief work in the district, before the onset of fever.

Purpose: To compare the stereopsis in patients with various grades of cataract and bilateral pseudophakia.

Methods: A cross-sectional observational study was conducted at a tertiary care center in South India from December 2016 to September 2018, wherein the stereoacuity of patients having bilateral senile cataract or bilateral pseudophakia, was measured using the Titmus Fly chart. Those with any form of squint, glaucoma or retinal pathology were excluded.

Purpose: To compare the posterior capsular opacification (PCO) after implantation of three types of hydrophobic square edge intraocular lenses (IOLs).

Methods: A single-center, hospital-based, cross-sectional, observational study was conducted wherein patients with senile cataract who had undergone phacoemulsification by a single surgeon, with the implantation of three different types of square edge, hydrophobic IOLs [Group 1: enVista, Bausch and Lomb; Group 2: Tecnis 1 ZCBOO, AMO and Group 3: Acrysof IQ SN60WF, Alcon], and followed up for 12 months were included. The PCO was graded clinically and scored using the EPCO 2000 software.

We present a novel and fully automated fundus image processing technique for glaucoma prescreening based on the rim-to-disc ratio (RDR). The technique accurately segments the optic disc and optic cup and then computes the RDR based on which it is possible to differentiate a normal fundus from a glaucomatous one. The technique performs a further categorization into normal, moderate, or severely glaucomatous classes following the disc-damage-likelihood scale (DDLS).

Purpose: The purpose of this study is to compare the contrast sensitivity function (CSF) between eyes of age-matched individuals with aspheric intraocular lens (IOL) and emmetropia.

Methods: A prospective hospital-based case-control study in South India was conducted to study the CSF in the eyes of patients between the ages of 50-60 years. The CSF was compared between those with emmetropia and those implanted with an indigenous aspheric IOL.

Purpose: The purpose was to study the retinopathy status in diabetic patients with a risk of diabetic foot (DF) syndrome visiting a tertiary care hospital in South India.

Methods: In this cross sectional study all patients with diabetes mellitus (DM) with a risk of DF syndrome, visiting a tertiary care hospital during the study period, underwent an ophthalmological evaluation for documentation of their retinopathy status.

Results: One hundred and eighty-two patients diagnosed to have a risk profile for DF syndrome were included in the study.
