Abstract

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).

Conclusion: A non-severe COVID-19 infection may cause a decrease in the VD of retinal SCP and DCP.

COVID-19 感染对黄斑毛细血管灌注的影响

目的：与COVID-19感染相关的血栓栓塞并发症屡见报端。本研究旨在通过光学相干断层血管成像（OCTA）评估既往非重度 COVID-19 感染对视网膜微循环的影响：43名PCR检测呈阳性的非重度COVID-19感染史患者（第1组）和30名健康对照组（第2组）共83只眼睛接受了详细的眼部检查，包括光学相干断层血管成像（OCTA，RTVue-XR Avanti）扫描。对浅层毛细血管丛（SCP）、深层毛细血管丛（DCP）和眼窝无血管区的血管密度（VD）进行了评估：从COVID-19 PCR检测阳性到眼部检查的平均时间为（144.6±82.2）天。与第 2 组相比，第 1 组眼窝和眼周区域的 SCP 和 DCP 的 VD 明显较低（p）：非严重的 COVID-19 感染可能会导致视网膜 SCP 和 DCP 的 VD 下降。
