BILATERAL CHOROIDAL OSTEOMA

Choroidal osteoma is a benign ossifying tumor characterized by mature bone replacing choroid. The condition is reported rarely and hence poses diagnostic difficulties. We report a case of a 25 year old lady who presented with complaint of defective vision in both eyes and was referred as a case of chorioretinal scar. A 25 yr old young lady presented to us with complaints of seeing dark shadows in front of eyes for the past 7 years. Her best corrected visual acuity in right eye was 636 and left eye was 660.Slit lamp evaluation revealed a normal anterior segment. Fundus examination showed peripapillary lesion that is yellow-white to orange-red in color. Thin, atrophic, yellow-gray regions with associated RPE atrophy were seen. Ultrasound B scan demonstrated calcification in the posterior pole. Optical Coherence Tomography (OCT) revealed loss of foveal thickness with sub and parafoveal hypereflective RPE suggestive of scar and calcification .The patient was investigated to rule out metabolic disorders.
