Abstract
Coronavirus disease 2019 (COVID-19) vaccinations have been associated with a higher risk of thromboembolic events. There have been no reports of central retinal artery occlusion (CRAO) after vaccination with the indigenously developed Covaxin, and worldwide, there has been only one such isolated case after administration of the AstraZeneca vaccine. We report a case of a 44-year-old healthy man who presented with sudden painless vision loss in his left eye 10 days after receiving Covaxin. His best-corrected visual acuity was minimal perception of light, with a relative afferent pupillary defect. Fundus examination revealed arterial attenuation and macular cherry red spot, suggesting an acute CRAO. Optical coherence tomography showed macular swelling and disorganization of the inner layers due to ischemic sequelae. Blood work was normal and cardiovascular examination was unremarkable. The patient was kept on follow-up. To our knowledge, this is the first case of an isolated CRAO after Covaxin administration, but further studies are needed to evaluate this potential association.
