Case Report: Choroidal osteoma: Bone in the eye

Abstract

We share a case of a 16-year-old girl who presented with blurring of vision in her left eye since 1 year, with fundus examination suggestive of choroidal osteoma. The detailed clinical, complimentary examinations, and multimodal imaging – fundus photo, optical coherence tomography, fundus fluorescein angiography, and B-scan ultrasonography – of the case are discussed. Choroidal osteoma is a rare benign ossifying tumor of unknown etiology characterized by mature bone replacing choroid, more commonly unilateral and predominantly affecting young females, typically manifesting in the teenage years or in the early 20s. Although choroidal osteoma is a rare benign tumor, accurate diagnosis is important because it is similar to amelanotic choroidal melanoma and metastatic choroidal carcinoma which require treatment and it is important to keep patients under observation for early detection of treatable choroidal neovascularization and other complications.
