title: [Bilateral choroidal osteoma--a case report].
abstract: Choroidal osteoma is a an extremely rare (especially located bilaterally), benign, intraocular tumor, the type of choristoma. It occurs between 2-3 decades of life, women are particularly vulnerable. The main complication in 1/3 cases is a subretinal neovascularization which may cause bleeding. The gradually progressive decalcification develops within the tumour over time, which causes atrophy of the retinal pigment epithelium and Bruch's membrane deformity. The article presents a case of a 26-year-old woman with bilateral choroidal osteoma complicated by subretinal hemorrhage; the diagnosis was based on clinical examination (biomicroscopy and indirect ophthalmoscopy) as well as specialised tests including: ultrasonography, optical coherence tomography, and fluorescein angiography.
