Context: Ocular complications due to diabetes mellitus (DM) were on the rise despite good literacy levels in South India. Aims: To assess knowledge and attitude toward DM diabetic retinopathy of general population a suburban town Settings Design: Door-to-door survey India May 2013. Materials Methods: A 30-point questionnaire was prepared data collected analyzed determine statistically knowledge, attitude, practice (KAP) scores also significant demographic associations. Results: In this...
To evaluate the causes of acute acquired comitant esotropia (AACE) in young adults and children setting COVID-19-induced home confinement.A retrospective, clinical study all patients, who presented to Pediatric Ophthalmology Strabismus services a tertiary eye care center South India from August 2020 January 2021 during COVID-19 pandemic, with acute-onset, esotropia.11 (73.3%) total 15 patients were students, above 10 years mean age 16.8 years. 12 (80%) had more than 8 hours near activity day...
Purpose: To suggest a low cost, non-contact smartphone-based screening system in retinopathy of prematurity (ROP), and to illustrate its potential clinical application as future tool for teleophthalmology. Methods: Neonatal intensive care unit (NICU)-based bedside ROP done between January 2018 May 2018. Documentation was by using smartphone +40D, +28D, or +20D indirect condensing lenses. By the coaxial light source phone, this works an ophthalmoscope that creates digital image fundus. With...
Diabetic retinopathy (DR) at risk of vision loss (referable DR) needs to be identified by retinal screening and referred an ophthalmologist. Existing automated algorithms have mostly been developed from images acquired with high cost mydriatic cameras cannot applied in the settings used most low- middle-income countries. In this prospective multicentre study, we a deep learning system (DLS) that detects referable DR using handheld non-mydriatic fundus camera non-technical field workers 20...
National estimates of the prevalence vision impairment and blindness in people with diabetes are required to inform resource allocation. People more susceptible conditions such as diabetic retinopathy that can impair vision; however, these often missed national studies. This study aims determine risk factors India. Data from SMART-India study, a cross-sectional survey coverage 42 147 Indian adults aged 40 years older, collected using complex sampling design, were used obtain nationally...
Aim: To provide the normative data of macular and retinal nerve fiber layer (RNFL) thickness in Indians using spectral domain OCT (Spectralis OCT, Heidelberg Engineering, Germany) to evaluate effects age, gender, refraction on these parameters. Design: Observational, cross-sectional study. Materials Methods: The eyes 105 healthy patients aged between 20-75 years, with no ocular disease best corrected visual acuity 20/20, were scanned standard scanning protocols by a single examiner....
To compare outcomes of macular hole surgery using sulfurhexafluoride (SF6) versus perfluoropropane (C3F8) gas.This is a retrospective, interventional, comparative study. A total 177 eyes 166 patients operated over 3-year period for idiopathic holes were included. Sixty-seven had tamponade with SF6 gas (Group 1), whereas 111 received C3F8 2) as the tamponading agent. The primary outcome measure was closure rate. Statistical analysis done SPSSv16.Spectral domain optical coherence...
Aims To develop and externally test deep learning (DL) models for assessing the image quality of three-dimensional (3D) macular scans from Cirrus Spectralis optical coherence tomography devices. Methods We retrospectively collected two data sets including 2277 3D 1557 scans, respectively, training (70%), fine-tuning (10%) internal validation (20%) electronic medical research records at The Chinese University Hong Kong Eye Centre Hospital. Scans with various eye diseases (eg, diabetic oedema,...
Chikungunya fever is a relatively rare from of vector-borne viral caused by chikungunya virus and spread bites the Aedes aegypti albopictus mosquito. Epidemics have been reported in past different parts world. Although had passive for quite some time, recent reports outbreaks several Southern India confirmed re-emergence this virus. Symptoms infection include abrupt onset fever, chills, headache, rash, severe joint pain, conjunctival injection photophobia. Ocular manifestations recently with...
Optic disc pit with associated maculopathy is a known entity. However, controversy exists regarding the source of subretinal fluid in these cases. In our series, we attempted to analyze morphologic changes seen optic and evaluate fluid.In this prospective observational case series 4 patients maculopathy, complete ophthalmic evaluation, fundus color photography enhanced depth imaging spectral-domain optical coherence tomography scanning disc, was carried out between January 2013 November...
Purpose: The "double-layer sign (DLS)" describes the shallow and irregular elevation of retinal pigment epithelium from underlying intact Bruch's membrane visualized on spectral domain optical coherence tomography. In this study, we evaluated frequency, characteristics space within double layer other features in pachychoroid spectrum to aid clinical diagnosis these variants. Methods: This retrospective study DLS multimodal imaging consecutive patients with a one four variants pachychoroid:...
The COVID-19 pandemic has brought new challenges to the health care community. Many of super-speciality practices are planning re-open after lockdown is lifted. However there lot apprehension in everyone's mind about conforming that would safeguard patients, ophthalmologists, healthcare workers as well taking adequate equipment minimize damage. aim this article develop preferred practice patterns, by developing a consensus amongst lead experts, help institutes individual vitreo-retina and...
To investigate the safety and efficacy of pneumatic displacement submacular hemorrhage without use intravitreal tissue plasminogen activator (tPA).In a prospective, consecutive, single-center, noncomparative, interventional case series, 20 consecutive patients with due to various etiologies (duration, 1-30 days; visual acuity, hand movements 20/125) were treated perfluoropropane gas injection followed by prone positioning for 5 days 7 days. Patients observed 1 day, days, 30 3 months, 6 year...
To analyse whether the size of internal limiting membrane peeling influences outcome macular hole surgery.Prospective, comparative, interventional study. Fifty eyes were included. Twenty-five had smaller (3-mm) peel (Group 1), whereas other 25 larger (5-mm) 2). Outcome measures closure rate, improvement in best corrected visual acuity, retinal nerve fiber layer, and ganglion cell layer thickness (0.5 mm, 1.5 2.5 mm temporal medial to fovea), external membrane, inner segment outer cone tip...
