Frosted Branch Angiitis

ABSTRACT

PURPOSE: Frosted branch angiitis is a rare retinal disease with the characteristic sheathing in the retinal vessels. We report a typical case of this disease. METHODS: A thirty-year-old woman complained of sudden decrease of visual acuity developed in both eyes three days ago. Visual acuity was 0.4 with several inflammatory cells in the anterior chambers of both eyes. There were diffuse vascular sheathing like frosted branch in both retinas. Fluorescein angiogram showed staining and leakage of dye along the vascular sheathing. RESULTS: Visual acuity recovered to 1.0 and retinal findings returned normal 2 weeks after treatment with the low dose of systemic steroid. There was no recurrence during follow-up period. CONCLUSIONS: Typical frosted branch angiitis occurs suddenly in both eyes of the young, and it responds well to treatment with the low dose of systemic steroid.
