(a) Color fundus photography of the left eye in 2011 demonstrating a region of peripapillary atrophy postlaser photocoagulation for the treatment of choroidal neovascular membrane (black arrow). (b) Color fundus photography of the left eye in 2017 demonstrating a well-demarcated, yellow lesion suggestive of choroidal osteoma (white arrow) developing adjacent to the previous area of peripapillary fibrosis. The left eye OCT demonstrating outer retinal atrophy postlaser photocoagulation (c and d) a choroidal mass consistent with choroidal osteoma (yellow star). OCT: Optical coherence tomography

The lesion was adjacent to an area of retinal atrophy due to prior laser photocoagulation for peripapillary CNVM [Figure 1a and b]. The lesion was located in the choroid on optical coherence tomography (OCT) [Figure 1c and d].
