Comparative study to evaluate retinal changes using spectral-domain optical coherence tomography in diabetics without diabetic retinopathy.

Purpose: To elucidate changes in the neuro-sensory retina at the macula, using spectral-domain optical coherence tomography (SD-OCT) in type 2 diabetics without clinical signs of diabetic retinopathy, and compare with healthy subjects.

Methods: This was a cross-sectional observational study, conducted at a tertiary eye institute from November 2018 to March 2020. Type 2 diabetics visiting the outpatient department with normal fundus (without any clinical signs of diabetic retinopathy) were taken as Group 1, and healthy subjects as Group 2.

Fundus evaluation in COVID-19 positives with non-severe disease.

Purpose: The aim of this work was to study and document retinal changes in coronavirus disease-2019 (COVID-19) positive patients with nonsevere disease using a nonmydriatic handheld fundus camera.

Methods: A cross-sectional observational study was conducted on patients affected by COVID-19 who were admitted at our center. Our study included patients with no, mild, and moderate symptoms (nonsevere cases).

Efficacy and safety of intraoperative intracameral mydriasis in manual small incision cataract surgery - A randomized controlled trial.

Purpose: The purpose of this study is to assess the efficacy and safety of intracameral mydriatic solution, as compared to preoperative topical mydriatics, in patients undergoing manual small incision cataract surgery (MSICS) under peribulbar anesthesia. To assess the sustainability of intracameral mydriasis in MSICS by monitoring pupil size at specific junctures during the surgery.

Methods: This trial recruited 127 patients, who underwent MSICS under peribulbar block.
