Abstract

Aim To identify retinal findings using dilated eye examination, which are possibly related to SARS-CoV-2 infection in hospitalised patients with confirmed severe COVID-19.

Methods In this cross-sectional study, hospitalised patients with confirmed severe COVID-19 in a single referral centre for the treatment of COVID-19, in Santo André, São Paulo Metropolitan Area, Brazil, underwent dilated eye examination of both eyes performed by a retina specialist. Findings were recorded using a portable digital fundus camera. Retinographies were analysed by two retina specialists. Medical records were reviewed for assessment of patient demographics, baseline comorbidities and clinical data.

Results There were a total of 18 patients, nine (50%) male, median IQR age of 62.5 (12) years. Ten of the 18 patients (55.6%; 95% CI 33.7 to 75.4) had abnormalities on dilated eye examination. The main findings were flame-shaped haemorrhages (N=4; 22.2%; 95% CI 9.0 to 45.2) and ischaemic pattern lesions (cotton wool spots and retinal sectorial pallor) (N=4; 22.2%; 95% CI 9.0 to 45.2), with one patient having both cotton wool spots and flame-shaped haemorrhages.

Conclusion These findings suggest that patients with severe COVID-19 have acute vascular lesions of the inner retina including flame-shaped haemorrhages and cotton wool spots. Further studies controlling for confounding factors are necessary to properly assess these findings so as to increase the understanding of COVID-19 pathophysiology and to identify new therapies.
