Abstract
We describe the case of a 76-year-old man who developed an asymptomatic choroidal osteoma in the left eye 10 years after receiving retinal laser photocoagulation for treatment of a peripapillary choroidal neovascular membrane. The choroidal osteoma presented as a progressively enlarging, well-circumscribed yellow lesion adjacent to the region of retinal fibrosis. Optical coherence tomography showed a choroidal lesion with superficial lamellations and ultrasonography demonstrated increased echogenicity. The choroidal osteoma was not encroaching on the fovea and is currently being monitored. This is only the third report of a de novo choroidal osteoma developing subsequent to retinal laser photocoagulation.
