Autologous platelet-rich plasma eye drop versus artificial tear eye drop for symptomatic dry eye disease: A prospective comparative interventional study.

Purpose: To evaluate and compare the efficacy of autologous platelet-rich plasma (aPRP) eye drop and artificial tear (AT) eye drop in moderate to severe symptomatic dry eye disease (DED).

Methods: This prospective interventional study included 121 eyes of 61 patients of moderate to severe DED. Patients were divided into aPRP (31 patients) and AT (30 patients) group.

Complete and incomplete lower motor neuron facial palsy in post-COVID-19 mucormycosis.

Purpose: To study facial nerve palsy (FNP) in post-COVID-19-mucormycosis patients and its ocular complications, report different presentations of FNP in such patients, and propose its etiopathogenesis based on presentation and clinico-radiologic localization.

Methods: A prospective cohort study was carried out in patients of post-COVID-19-mucormycosis who presented at our tertiary center, over a period of 3 months. Motor and sensory examination of the facial nerve was done to diagnose FNP and localize the lesion clinically.

COVID-19-associated mucormycosis: Preliminary report from a tertiary eye care centre.

Purpose: Mucormycosis is a life-threatening infection that has made sudden comeback in COVID-19 era. We conducted this study to determine demography, site of involvement, management, and outcome in these patients.

Methods: All cases presenting with signs and symptoms of mucormycosis were thoroughly evaluated and confirmed diagnosis was made on demonstration of fungi in the tissue (or body fluids) either by direct microscopy and/or culture.

Study of retinal nerve fiber layer analysis using optical coherence tomography in different demyelinating diseases and its correlation with the severity of visual impairment.

Purpose: This purpose of this study was to find the association between severity of visual impairment and retinal nerve fiber layer (RNFL) thickness loss in different demyelinating diseases using optical coherence tomography (OCT) and, simultaneously, assess the fellow eye for subclinical RNFL thickness loss.

Methods: This cross-sectional, observational study included 60 eyes of 30 patients above the age of 20 years with diagnosed cases of multiple sclerosis (MS), neuromyelitis optica (NMO), and clinically isolated syndrome (CIS) who had history of (h/o) optic neuritis (ON) attack were included. Participants included in the study group underwent best-corrected visual acuity (BCVA) measurement, color perception, swinging flashlight test, slit-lamp examination, and dilated fundus examination (DFE).
