A 22-year-old Indian man presented with gradual painless diminution of vision in both eyes since 4 months. His best-corrected visual acuity was 20/200 OU. His anterior segment examination results were unremarkable. Fundus photographs revealed bilateral well-circumscribed yellowish-orange lesions at the posterior pole. Multiple branching vascular networks were observed on its surface with yellowish-gray lesion at the fovea (Figure). A diagnosis of bilateral choroidal osteoma with choroidal neovascularization (CNV) was made. The CNV was confirmed by optical coherence tomography. Choroidal osteomas are rare, benign tumors characterized by mature cancellous bone in the choroid. They are usually unilateral and present in young women.1 They are slow growing and can undergo spontaneous decalcification2 and resolution.3 Choroidal osteomas are also known to be associated with CNV, serous retinal detachment, and hemorrhage.2
