OBJECTIVES: Thromboembolic complications related to the COVID-19 infection are frequently reported. This study aims to evaluate the impact of a prior non-severe COVID-19 infection on retinal microcirculation with optical coherence tomography angiography (OCTA).
METHODS: A total of 83 eyes of 43 patients with a history of non-severe COVID-19 infection confirmed with a positive PCR test (Group 1) and 30 healthy controls (Group 2) underwent detailed eye examination, including optic coherence tomography angiography (OCTA, RTVue-XR Avanti) scanning. Vessel densities (VD) in the superficial capillary plexus (SCP), deep capillary plexus (DCP), and foveal avascular zone were evaluated.
RESULTS: The mean duration between the COVID-19 positive PCR test and ocular examination was 144.6±82.2 days. VD of SCP and DCP in the foveal and perifoveal regions were significantly lower in Group 1 compared to Group 2 (p<0.05).
DISCUSSION AND CONCLUSION: A non-severe COVID-19 infection may cause a decrease in the VD of retinal SCP and DCP.

Keywords: COVID-19, optical coherence tomography angiography, retinal capillary perfusion.
