DIFFERENTIAL-DIAGNOSIS OF CHOROIDAL MELANOMAS AND NEVI USING SCANNINGLASER OPHTHALMOSCOPICAL INDOCYANINE GREEN ANGIOGRAPHY

Fluorescein angiography is one of several standard ancillary diagnosti c techniques in the evaluation of suspected malignant choroidal melano ma. Indocyanine green choroidal angiography has improved visibility of the choroidal circulation in comparison with fluorescein angiography. Studies concerning the use of indocyanine green angiography in the di fferentiation between nevi and melanomas have been few and the results inconclusive. A case of a choroidal melanoma (verified by histopathol ogical examination) and a nevus in the same eye is documented by fluor escein and indocyanine green choroidal angiography performed by scanni ng laser ophthalmoscopy. This modality may be considered in the evalua tion of a suspected malignant choroidal melanoma.
