Bilateral Choroidal Osteoma with Secondary Choroidal Neovascularization in a Teenager: A Rare Case

Choroidal osteoma is a rare, benign ossifying tumor that may lead to vision loss due to complications such as choroidal neovascularization (CNV). While typically unilateral in young females, bilateral involvement is less common. This report presents a 16-year-old girl with gradual, painless bilateral vision loss. Her best-corrected visual acuity (BCVA) was 6/60 in the right eye and 6/36 in the left. Fundus examination revealed bilateral, orange, scalloped choroidal lesions in the macula with surface vascular networks. Fluorescein angiography confirmed CNV in both eyes. The patient received three intravitreal injections of ranibizumab (0.3 mg/0.05 ml) in each eye at four-week intervals.
