Purpose: To characterize choroidal nevi with the OCT/SLO and to compare their features to clinical appearance using standard fundus photography. Methods: The OCT/SLO combines optical coherence tomography and confocal scanning ophthalmoscopy. It is able to acquire both longitudinal (B–scan) and coronal (C–scan) OCTs, as well as the corresponding confocal SLO image. A retrospective review was made of cases of choroidal nevi imaged using the OCT/SLO. Results: 5 consecutive patients with clinically diagnosed choroidal nevi of the posterior pole were imaged with the OCT/SLO. The SLO images all displayed hyper–reflective lesions whose dimensions overlapped well with the borders of the nevi on fundus photographs. There was an inverse relationship between the brightness of the OCT/SLO image and the amount of pigmentation in the lesion. We also found slight differences in the appearance of nevi located near the macula versus the periphery. Conclusions: OCT/SLO is a useful tool in imaging choroidal nevi and may help reveal subtleties that are not evident on clinical examination alone. Hopefully this will eventually facilitate superior identification of lesions suspicious for malignancy.
