Unilateral Purtscher-like retinopathy post-COVID-19.

A 32-year-old male with no known systemic illness presented with unilateral Purtscher-like retinopathy in his left eye 2 weeks after recovering from a severe COVID-19 infection. Fundus examination revealed areas of intraretinal whitening and few cotton wool spots. Multimodal imaging findings were consistent with embolic occlusion of capillaries seen in Purtscher-like retinopathy. The case highlights the effect of virus-directed coagulation cascade activation leading to unilateral microvasculopathy in our patient. The case adds to the spectrum of COVID-19 retinopathy and presses that retina screening strategies should be established for patients suffering from or recovering from severe COVID-19 infection.

Retinal vasoocclusive spectrum following COVID-19.

The coagulation abnormalities and thromboembolic complications of coronavirus 2 (SARS-CoV-2) are now a well-established fact. The hypercoagulable state, the tendency for thromboembolism, and a cytokine surge state have been the exclusive reasons for multiorgan failure and other morbidities that have been regularly reported in COVID-19 patients. Ocular involvement in patients with active disease and those who have recovered is uncommon but not rare. We report a case series of four patients with CRVO, BRVO, CRAO, and vitreous hemorrhage in patients with proven COVID-19 infection and no other systemic ailments. The case series also tries to correlate the elevated D-dimer values, which signify a plausible prothrombotic state with the vaso-occlusive phenomenon in the retina leading to significant visual morbidity.
