Swept source: optical coherence tomography angiography features of choroidal osteoma with choroidal neovascular membrane

Abstract

A 16-year-old boy presented with best-corrected visual acuity of 6/18 OD. OS was within normal limits, as was anterior segment OD. A focal whitish-yellow plaque lesion with overlying areas of depigmentation, and retinal atrophy in the central and superior lateral macula were noted in OD. A choroidal neovascular membrane (CNVM) with subretinal haemorrhage was seen at the lesion's inferior medial edge, involving the fovea (figure 1A). Therefore, diagnosis of choroidal osteoma1 (CO) was made and confirmed on sonography, with a highly acoustic elevated lesion causing a corresponding shadow (figure 1B).
