A 48-year-old man, with hypertension, type 2 diabetes mellitus, and stage 4 chronic kidney disease, diagnosed with COVID-19 1 month ago presented to the ophthalmology department with blurred vision in both eyes for 2 weeks. Ocular examination revealed a classic clinical presentation of CRVO in both eyes. Optical coherence tomography revealed increased central macular thickness with intraretinal and subretinal fluid in both eyes. Laboratory data revealed elevated D-dimer and C-reactive protein (CRP) levels. The levels of other hypercoagulability markers were normal.
