Choroidal osteoma is rare clinical entity of unknown etiology, characterized by formation of mature cancellous bone within the choroid. It typically affects young females, with no racial predilection. Vision loss occurs mainly due to photoreceptor degeneration secondary to decalcification and/or development of choroidal neovascularization especially if located at the sub foveal area. Our case is 9 y old male child identified incidentally with multiple yellowish white well demarcated lesions in the left eye suggestive of choroidal osteoma associated with nearby areas of RPE (retinal pigment epithelium) atrophy and depigmentation. SD-OCT (spectral domain optical coherence tomography) demonstrated high reflectivity from the choroid and atrophy of the overlying retinal layers. USG B-scan demonstrated multiple highly reflective calcified lesions within the choroid suggestive of choroidal osteoma.
