ABSTRACT

Choroidal osteoma is a bone tumor lesion of unknown etiology, frequently affecting young white females between the 2nd and 3rd decades of life and maybe in association to sub retinal neovascularization.
We report the case of a 39 year old male presented with one week history of metamorphopsia in the left eye and visual acuity of 20/20 in both eyes. The remainder of the eye examination yielded normal results except for abnormalities in the left eye that revealed a yellow-white well defined choroidal lesion inferior to the optic disc, with associated hemorrhage and serous detachment of the neurosensorial retina. A/B ultrasound examination confirmed the presence of a flat, irregular lesion of the choroid with high amplitude echoes and posterior acoustic shadowing. Orbital computed tomography scan showed a calcified density inferior to the optic nerve head. Fluorescein angiographic examination confirmed the presence of a patchy, hyperfluorescent area consistent with subretinal neovascular membrane within the choroidal lesion. The diagnosis of choroidal osteoma complicated by subretinal neovascular membrane was made and treated with argon laser photocoagulation. The subject remained asymptomatic within a 3 year follow up.
