Choroidal Osteoma with Choroidal Neovascularization and Focal Choroidal Excavation

Abstract

A 28-year-old female presented with recent onset of metamorphopsia in left eye. Best corrected visual acuity was 20/20 in right eye and 20/600 in left eye. Colour fundus photograph revealed orange yellow peripapillary lesion crowning the optic disc. Fundus Fluorescein Angiography revealed presence of choroidal neovascular membrane (CNV) type 2 in juxta-foveal region. Enhanced Depth Imaging Optical Coherence Tomography confirmed presence of CNV and conforming type of focal choroidal excavation (FCE). Diagnosis of choroidal osteoma with conforming FCE and CNV type 2 was made. FCE may be seen in choroidal osteoma with CNV, primarily in areas adjacent to decalcification.
