Bilateral choroidal osteoma with subretinal neovascularization.
Choroidal osteoma is a rare entity, reported previously mainly in females. We report a case of bilateral choroidal osteoma in a 15-year-old boy. Ultrasonography and computerized tomography findings were key to establishing the diagnosis. During two years' follow-up, there was observable growth in the tumor size. Leakage from subretinal neovascular tufts covering the tumor caused visual deterioration. Photocoagulation of the subretinal new vessels was performed twice, with limited success, but the value of this treatment in choroidal osteomas needs further study.
