OCTA Study: Retinal Vascular Changes in Patients With SARS-CoV-2 Infection

Optical Coherence Tomography Angiography in Patients Affected by SARS-CoV-2 Infection: a Pilot Study

This study evaluates the retinal vascular features using optical coherence tomography angiography in patients that have been affected by COVID-19.

To investigate the potential role of optical coherence tomography angiography in identifying the changes in retinal vessel density in patients that have been affected by COVID-19.

The optical coherence tomography angiography represents a noninvasive diagnostic technique that allows a detailed analysis of retinal vascular features.
