Photoreceptor Arrangement Changes Secondary to Choroidal Nevus.

IMPORTANCE: Although mostly asymptomatic, patients with choroidal nevi carry a moderate risk for malignant transformation and visual loss. A novel noninvasive imaging assessment could change the current clinical evaluation of choroidal nevi. OBSERVATION: Three patients with a recent diagnosis of choroidal nevi underwent a novel adaptive optical assessment that detected potential photoreceptor abnormalities in the retina overlying the choroidal nevi. CONCLUSIONS AND RELEVANCE: Adaptive optics imaging may provide high-resolution en face images of retinal structural changes in the photoreceptor mosaic overlying the choroidal nevi. Cone attenuation may be an important component of structural damage in choroidal nevi and may correlate and possibly predict functional visual loss.
