Analysis of retinal vessel density using optical coherence tomography angiography in patients affected by COVID-19

Purpose : Patients affected by Coronavirus disease 2019 (Covid-19) suffer from a hypercoagulable state that may potentially affect the retinal and choroidal circulation. The aim of this study was to determine whether retinal and choriocapillaris vessel density (VD) as measured by optical coherence tomography angiography (OCTA) resulted abnormal in patients previously affected by Covid-19 Methods : The right eye of sixty patients who tested...
