Peripapillary choroidal neovascularization in best disease.

Abstract

Best disease is an autosomal dominant retinal dystrophy with a variable phenotypic expression. Clinically, it is characterized by a vitelliform lesion in the macula because of the deposition of yellow material in a dome-shaped configuration, believed to be lipofuscin that accumulates within and beneath the retinal pigment epithelium. Best disease is occasionally complicated by the development of choroidal neovascularization (CNV), which typically occurs in the macula. We report a case of peripapillary CNV in Best disease. Interventional case report. A 12-year-old boy who was previously diagnosed with Best disease was treated with reduced fluence photodynamic therapy for subfoveal CNV in the right eye. After 2 months, he presented with peripapillary CNV in the left eye, which was treated with repeated sessions of reduced fluence photodynamic therapy. Ophthalmologists must be aware that peripapillary CNV may occasionally complicate Best disease and can be successfully treated with photodynamic therapy.
