title: De novo appearance of a choroidal osteoma in an eye with previous branch retinal vein occlusion.
abstract: This report describes the de novo appearance of a choroidal osteoma occurring 8 years after laser photocoagulation for previous branch retinal vein occlusion (BRVO). A 62-year-old man presented with an asymptomatic yellowish orange lesion in the macula on fundus examination of his left eye during a regular follow-up visit for bilateral BRVO associated with macular edema that had previously been treated with laser photocoagulation. The lesion was observed for 1.5 years until a decrease in vision occurred. Fundus photography revealed a yellow-to-orange, well-defined lesion in the macular region. Fluorescein angiography was consistent with choroidal neovascularization (CNV). Optical coherence tomography and B-scan ultrasonography showed features consistent with choroidal osteoma. This is the first report of the de novo appearance of a choroidal osteoma occurring years after laser photocoagulation for BRVO. CNV developed secondary to the lesion, which was treated with intravitreal bevacizumab, leading to subjective and anatomic improvement.
