PP157 : Bone in the eye – a diagnostic dilemma

Dr.SARANYA SETTU

Choroidal osteoma is a rare intraocular tumor in which mature bone replaces the full thickness of choroid in the juxtapapillary or macular region. We present a case of atypical presentation of choroidal osteoma with large subretinal fluid in the absence of choroidal neovascularisation – presenting a diagnostic dilemma. A 16 years old female patient presented with sudden painless loss of vision in right eye; fundus examination showed a large serous elevation in superior and temporal quadrant extending from the disc and encompassing the fovea and an orange yellow elevated lesion superior to optic nerve. Optical coherence imaging showed subretinal fluid and blood filled spaces. Fundus fluorescein angiography showed blocked fluorescence. Patient was treated with intravitreal bevacizumab 1.25mg. At one month followup, the subretinal fluid disappeared revealing an orange yellow elevated juxtapapillary lesion with clearly defined margins suggestive of choroidal osteoma.
