Acute frosted retinal periphlebitis.

A 30-year-old woman developed bilateral acute vision loss without any systemic symptoms. There was diffuse retinal edema and thick perivenous sheathing with moderate vitreous inflammation. Fluorescein angiography showed late staining and dye leakage from diseased vessels. Oral corticosteroid treatment stabilized the visual acuity and fundus of the left eye but did not halt the progression to total fibrosis in the right eye.
