Evaluation of acute effects of pulmonary involvement and hypoxia on retina and choroid in coronavirus disease 2019: An optic coherence tomography study.

Purpose: We investigated the acute subclinical choroidal and retinal changes caused by Coronavirus Disease 2019 (COVID-19) in patients with and without pulmonary involvement, using spectral domain optic coherence tomography.

Methods: This prospective case-control study included COVID-19 patients: 50 with pulmonary involvement and 118 with non-pulmonary involvement. All patients were examined 1 month after recovering from COVID-19.

The role of meibomian gland dysfunction on the development of dry eye disease in patients with facial nerve palsy.

Purpose: To investigate whether meibomian gland dysfunction is the cause of dry eye in facial nerve palsy and to identify the possible relationship between the grades and durations of facial nerve palsy and meibomian gland dysfunction.

Methods: This prospective observational study included 63 patients with unilateral facial nerve palsy. Facial nerve function and severity were assessed using the House-Brackmann grading system.

Meibomian Gland Dysfunction and Its Association With Ocular Discomfort in Patients With Ocular Prosthesis.

Objective: To investigate the effects of ocular prosthesis on meibomian glands and also to identify the role of meibomian gland dysfunction (MGD) on ocular discomfort in prosthetic eyes.

Methods: This prospective study included 55 patients who had been wearing unilateral ocular prosthesis for more than 1 year. A 15-item questionnaire regarding MGD-related ocular symptoms was administered to all patients.

Familial Exudative Retinopathy: A Case and Family Analysis.

Familial exudative vitreoretinopathy (FEVR) is a rare inherited disorder of retinal angiogenesis. A 49-year-old male patient was referred to our clinic for retinal vascular occlusion. His history, clinical findings, and fundus fluorescein angiography findings were evaluated.
