Frosted branch angiitis (FBA), a rare form of retinal vasculitis presenting as bilateral perivascular sheathing, resembling the appearance of frosted tree branches in winter, was first reported by Ito et al.1 in 1976, in a young immunocompetent boy. FBA predominantly affects healthy young patients, the youngest reported in an 11-month-old infant2 and oldest in a 42-year-old patient.3 Classical symptoms include sudden onset of blurred vision with floaters and photopsiae. Fundus examination shows widespread perivascular translucent sheathing affecting both arterioles and venules, more commonly latter. Fluorescein angiography shows late staining of vessels with no obstruction of blood flow. Electroretinogram shows reduced amplitude and visual fields show generalized constriction. Medline search did not show any case of frosted branch angiitis in a patient with typhoid fever.
