Purpose:
To describe a case of unilateral frosted branch angiitis in a patient with abdominal tuberculosis.
Methods:
Observational case report.
Results:
A 17-year-old girl with chronic abdominal pain, cough, and amenorrhea for 5 months presented with complaints of sudden diminution of vision in both eyes for 1 day. Fundus examination of the right eye showed disk edema, dilated tortuous vessels with perivascular sheathing (frosted branch angiitis), retinal hemorrhages, and macular edema. The left eye had areas of healed choroiditis. Duodenal biopsy showed features suggestive of tuberculosis. She was treated with antituberculosis therapy along with oral steroids after which the ocular condition responded dramatically.
Conclusion:
Frosted branch angiitis can be a rare manifestation of intraocular tuberculosis.
