Posterior segment findings in post-Covid mucormycosis: A cross-sectional study

Abstract

To assess the posterior segment findings in cases presenting with post covid mucormycosis. A cross-sectional observational study was conducted on patients presented with post-covid mucormycosis who were admitted in our hospital during the time period from 1/5/2021 to 1/9/2021. Our study included cases with and without orbital involvement. Anterior segment examination and fundus examination using indirect ophthalmoscopy was done. Findings were photo documented with fundus camera.: In a cohort of 248 patients, 183 (73.7%) were males and 65 (26.2%) were females. 210 (84.67%) were diabetics. The mean age was 50.00 +/-12.33 years. A total of 480 eyes were evaluated, out of which 151 (31.45%) had orbital involvement. Of these 151, 65 had normal fundus, 26 (17.21%) had diabetic retinopathy, 22 had CRAO, 12 had disc pallor, 10 had disc edema and 16 had miscellaneous changes. Out of 329 uninvolved eyes, 239 had normal fundus, 53 (16.10%) had diabetic retinopathy. There was no statistically significant difference between the prevalence of diabetic retinopathy in eyes with orbital involvement and without orbital involvement (p=.39). One-third of the patients with post-covid mucormycosis had retinal findings. These are related to direct disease manifestation as well as underlying co-morbidities.
