Abstract

Background: Numerous ocular signs have been documented as a result of COVID-19 infections, in addition to severe systemic disease. These manifestations included choroidal and retinal changes. This study aimed to investigate the rate of retinal and choroidal circulation in post COVID-19 patients.

Aim of the work: To assess retinal and choroidal circulation in post COVID-19 patients.

Patient and methods: In an observational cross-sectional study, 40 eyes of 20 post-COVID-19 patients attending ophthalmology outpatient clinics of Al-Azhar University hospitals were recruited in the period from mid-June 2022 for 6 months. The following data were collected: Detailed medical history, Complete ophthalmological examination including: Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), Examining the anterior segment with a slit lamp, measuring the intraocular pressure (IOP), and checking the fundus. A Topcon OCT Triton was utilized to perform Optical Soundness Tomography Angiography (OCTA), too, and Fundus Fluorescein Angiography (FFA) was performed utilizing a Topcon TRC 50DX-Group retinal camera.

Results: In the current study, the mean age was 27.5 years. Most patients were males. The mean body mass index was 26.61 ± 4.13. As regard ophthalmic examination, most members were normal and only few cases showed some abnormalities. As regard FFA and OCTA, most of the study members were within the normal range only few cases showed some abnormalities. Finally, and unlike other studies, our study has proven that COVID-19 may pass without causing retinal microvascular abnormalities.

Conclusion: Retinal and choroidal circulation in our study was not markedly affected during COVID-19 pandemic.
