Post-Fever Retinitis

A 34-year-old male presented with a gradual, painless decrease in distant vision in the left more than the right in the past 15 days. He had a history of an episode of fever seven days prior to ocular symptoms and had been treated with oral Cefixime and antipyretics. On detailed fundus examination, both eyes showed creamy white superficial lesions with ill-defined margins, suggestive of retinitis, with a few hemorrhages along the inferior arcade associated with sheathing of vessels and telangiectatic vessels near the lesion. Fundus fluorescein angiography (FFA) of both eyes in the venous phase depicted blocked fluorescence at the site of retinitis lesions with hyperfluorescence at their borders. Optical coherence tomography (OCT) of both eyes showed inner retinal layer hyper-reflectivity with neurosensory detachment (NSD) with hyper-reflective deposits in it and dilated choroidal vessels. The diagnosis of both eyes' post-fever retinitis (PFR) was made, and he was investigated for complete blood count, peripheral smear, erythrocyte sedimentation rate, and HIV Tridot test, which were normal. He was treated with intravitreal triamcinolone acetonide (2 mg/0.05 ml) in both eyes.
