The aim of this study was to evaluate the effects of COVID-19 on central foveal and choroidal thicknesses. Thirty-two patients with a positive SARS-CoV-2 PCR test who received outpatient treatment within the previous two months and 32 healthy controls were included in the study. Patients requiring hospitalization due to COVID-19 as well as the patients who received either intensive care support and/or antiplatelet therapy, smokers, or patients with systemic or ocular diseases were excluded from the study. After full ophthalmological examination, central foveal and choroidal thicknesses were evaluated by using optical coherence tomography. Statistical analysis of the study data demonstrated no significant difference between the groups in terms of age or gender (p>0.05). There was also no statistically significant difference between the groups in terms of central foveal thickness, central choroidal thickness, or nasal 500, nasal 1500, temporal 500, or temporal 500-micron distances (p>0.05 for all parameters). Choroidal and retinal thicknesses were not affected in patients with recent mild COVID 19 without comorbidities.

轻度 COVID-19 感染患者的中央凹和脉络膜厚度如何受到影响？

本研究的目的是评估 COVID-19 对中央凹和脉络膜厚度的影响。该研究纳入了 32 名在过去两个月内接受过门诊治疗的 SARS-CoV-2 PCR 检测呈阳性的患者和 32 名健康对照者。因 COVID-19 需要住院的患者以及接受重症监护支持和/或抗血小板治疗的患者、吸烟者或患有全身或眼部疾病的患者被排除在研究之外。经过全面的眼科检查后，使用光学相干断层扫描评估中央凹和脉络膜的厚度。研究数据的统计分析表明，各组之间在年龄或性别方面没有显着差异（p>0.05）。各组之间在中央凹厚度、中央脉络膜厚度或鼻 500、鼻 1500、颞 500 或颞 500 微米距离方面也没有统计学显着差异（所有参数 p>0.05）。最近患有轻度 COVID-19 且无合并症的患者的脉络膜和视网膜厚度没有受到影响。
