Choroidal osteoma and pattern dystrophy of retinal pigment epithelium.

Objective: To describe co-occurrence of choroidal osteoma in a patient with pattern dystrophy of retinal pigment epithelium.

Methods: Clinical case report

Results: A young female presented with decreased vision in the right eye due to decalcification of choroidal osteoma. Multimodal imaging including fundus autofluorescence, fluorescein angiography and optical coherence tomography showed features of pattern dystrophy of retinal pigment epithelium that simulates the Stargardt disease.

Conclusions: This co-occurrence of choroidal osteoma and pattern dystrophy is likely to be incidental. Multimodal imaging may help in differentiating pattern dystrophy of retinal pigment epithelium that simulates Stargardt disease from Stargardt disease.
