Arteriolar occlusion in post-fever retinitis; Case report with review of literature

Abstract

We report a rare association of retinal vascular occlusion in post-fever retinitis (PFR). A 58-year-old male presented with a vision of 3/60 in the right eye and 6/24 in the left eye 1 month after an episode of fever. Examination revealed vitritis (4+), cotton wool spots, venous beading and hemorrhages in both eyes, and retinal whitening superior and temporal to the fovea in the right eye suggestive of arteriolar occlusion. Optical coherence tomography (OCT) showed inner retinal hyperreflectivity, and OCT angiography showed flow-void areas corresponding to the area of whitening confirming occlusion. Our findings, together with those from previous studies, show that retinal vascular occlusive events, predominantly involving the arterial circulation, may complicate PFR.
