Optical Coherence Tomography Angiography Parameters in Indian Patients With Central Serous Chorioretinopathy.

Background In this study, we aimed to evaluate optical coherence tomography angiography (OCTA) parameters among Indian patients affected with central serous chorioretinopathy (CSCR). Methodology A cross-sectional study on Indian patients having unilateral or bilateral affection with CSCR was conducted at the Department of Ophthalmology, Guru Nanak Eye Centre, and Maulana Azad Medical College, New Delhi. A history of ocular symptoms such as a diminution of vision, metamorphopsia, decreased contrast sensitivity (CS), and defective color vision (CV) and their duration were obtained.

Color perception on Ishihara plates with red lenses in subjects with low vision due to retinal diseases.

Purpose: This study aimed to evaluate color perception (CP) changes on Ishihara plates following red-tinted contact lenses in subjects with low vision (LV) from retinal diseases.

Methods: A cross-sectional observational study without control involved 84 subjects, aged 20-70 years, having LV from retinal diseases to examine CP changes following wearing red-tinted contact lenses. The subjects viewed Ishihara plates, with each eye separately, before and after wearing red lenses in two categories: "plates 1-21" and "plates 22-25".

The Association of Neovascularization With Optical Coherence Tomography Angiography Parameters in Proliferative Diabetic Retinopathy.

Aim: We aim to find an association between neovascularization (NVn) and optical coherence tomography angiography (OCTA) parameters in proliferative diabetic retinopathy (PDR).

Methods: In a prospective study, 41 subjects including 28 (68%) males and 13 (32%) females having PDR were examined for neovascularization disc (NVD) and neovascularization elsewhere (NVE) clinically and with fundus fluorescein angiography (FFA). A total of 79 eyes were found to be involved.

A Case of Full Thickness Parafoveal Hole Associated with Chorio-Retinal Atrophy.

Background: An idiopathic full-thickness parafoveal hole (PFH) in the absence of trauma or intraocular surgery is a rare finding.

Case: A 60-year-female who did not gain good vision following an uneventful phacoemulsification with intraocular lens (IOL) implantation in the right eye (RE) consulted a retina specialist, one year after her cataract surgery. There was no history of trauma, radiation exposure, reduced scotopic vision, or any other intraocular surgery.

Evaluating the Quantitative Foveal Avascular Zone and Retino-Choroidal Vessel Density Using Optical Coherence Tomography Angiography in a Healthy Indian Population.

Objective: The foveal avascular zone (FAZ) is the round capillary-free zone within the macula and is supplied only by a single-layered parafoveal capillary arcade. This study aimed to evaluate the quantitative FAZ and retino-choroidal vessel density (VD) using optical coherence tomography angiography (OCTA) in a healthy Indian population.

Methods: This was a cross-sectional observational study that was conducted for evaluating the quantitative FAZ and retino-choroidal VD of 200 eyes of 100 healthy Indian subjects, including 62 males and 38 females (age range 17-50 years) having the best-corrected visual acuity (BCVA) of logMAR 0 (20/20; 6/6) and spherical equivalent refractive error of not more than 1 D.

Iridofundal Coloboma Associated with Vitreous Haemorrhage and an Intraocular Mass: A Case Report.

Introduction: Iridofundal colobomas, being developmental defects, are known to be accompanied by several ocular anomalies but an association with vitreous hemorrhage and an intraocular mass has not been reported earlier.

Case: We report a case of an 18 years old subject having iridofundal coloboma in both eyes and an association of vitreous hemorrhage and an intraocular mass in the left eye. The diagnosis was confirmed with a detailed ocular examination, fundus fluorescein angiography, swept-source optical coherence tomography and ultrasonography.

Central Retinal Vein Occlusion Following the First Dose of COVID Vaccine.

The reports of vascular adverse events in the eye following COVID-19 vaccination are infrequent. We report the case of a healthy male who developed central retinal vein occlusion in his left eye three days following administration of the first dose of Covishield vaccine. As the underlying systemic and ocular risk factors were absent and laboratory investigations were normal, vein occlusion appeared to probably result from the vaccine.

Assessing contrast sensitivity change in retinal diseases with use of yellow-amber NoIR glasses.

Purpose: The purpose of this study was to assess change of contrast sensitivity (CS) in subjects having retinal diseases with yellow-amber no infrared (NoIR) glasses used as low vision aid (LVA).

Methods: We examined CS in 82 low vision (LV) subjects having retinal diseases with Pelli Robson Chart at 1 m distance before and after wearing yellow-amber NoIR glasses. We also found type of retinal affection and macular optical coherence tomography (OCT) features.

Predictors of Retinal Nerve Fiber Layer Parameters Following Scleral Buckling Surgery in Primary Rhegmatogenous Retinal Detachment.

Objective: This study aimed to examine predictors of retinal nerve fiber layer (RNFL) parameters following scleral buckling (SB) surgery for primary rhegmatogenous retinal detachment (RRD) and to determine the influence of the magnitude of change in qualitative and quantitative parameters on RNFL.

Methods:  In an observational prospective study, 40 subjects who underwent successful retinal reattachment with SB surgery done within one month of RRD were evaluated for the parameters of best-corrected visual acuity (BCVA), refractive error, intraocular pressure (IOP), axial length (AL), anterior chamber depth (ACD), angle opening distance (AOD 500 and AOD 750), trabecular iris surface area (TISA 500 and TISA 750), visual fields, and ganglion cell count (GCC) and RNFL before and three months after SB. We additionally noted qualitative factors like extent, location, and type of buckle; phakic status; and grade of proliferative vitreoretinopathy in the affected eye.

Role of improved distance and near visual acuity with low vision aids to enhance stereopsis in retinal diseases.

Purpose: The purpose of this study was to examine role of improved distance and near best-corrected visual acuity (DBCVA and NBCVA) with use of magnification devices to enhance stereopsis in low vision (LV) subjects having retinal diseases.

Methods: In a cross-sectional observational study without control, 84 subjects having LV due to retinal diseases were examined for an improvement of BCVA with use of magnifying low vision aids (LVAs) (2X for DBCVA and 3X for NBCVA). The stereopsis scores on titmus fly test were recorded with near refractive correction "on" and then with 3X magnification.

Optical Coherence Tomography Angiography following Scleral Buckling Surgery.

Introduction: The retinal changes following scleral buckling surgery (SBS) for rhegmatogenous retinal detachment (RRD) have been rarely evaluated with optical coherence tomography angiography (OCTA).

Methods: A 40 years old male presented with subtotal RD involving the macula and had best corrected visual acuity of logmar 2.3 in the affected right eye.

Introduction: The orbital manifestations of acquired immunodeficiency syndrome(AIDS) are uncommon.

Objective: To provide a review of orbital manifestations of AIDS, the predisposing factors, investigations, treatment and outcome.

Materials And Methods: Meticulous and systematic literature search of Pubmed to identify manuscripts describing orbital manifestations of AIDS was done and the articles were reviewed.

A neonate with anorectal malformation with rare limb defects report of a case.

A 2-day-old male infant, born of a non-consanguineous marriage and uneventful pregnancy was found to have anomalies of vertebral, anal, cardiac, tracheo-esophageal, radial and limb (VACTERL) association. The striking feature was the simultaneous occurrence of two rare limb defects of right upper and lower limb in the baby who also had imperforate anus and ventricular septal defect. These limb defects were-meromelia of the right upper limb (due to transverse deficiency of right humerus and absence of all the bony elements distally), and a short right lower limb due to co-existence of proximal femoral hypoplasia and fibular hemimelia.

Temporary transgastric fistula occlusion as salvage procedure in neonates with esophageal atresia with wide distal fistula and moderate to severe pneumonia.

A method to achieve distal fistula occlusion by inflating the balloon of a catheter placed at the gastroesophageal junction via a transgastric route was tried in seven consecutive neonates with esophageal atresia and wide distal fistula. Due to associated moderate or severe pneumonia, these infants were at poor anesthetic risk for the definitive repair. The procedure was done under local anesthesia with mild sedation and took an average of half an hour for completion.

A rare presentation of abortive epispadiac urethral duplication and vanishing midurethra.

We report a 4-year-old boy with a hitherto undescribed case of abortive epispadiac duplication of the urethra presenting as a blind-ending penopubic sinus proximally and a mucosa-lined groove overlying the glanular corona distally but with absent midurethra. The patient was treated for cosmetic reasons with good results. A plausible embryological genesis of this defect is discussed.
