Abstract
Additional follow-up studies on a series of choroidal nevi previously reported showed no transformation to malignant melanoma. This rarity of malignant transformation, coupled with the occasional difficulty of distinguishing clinically between a choroidal nevus and a very early malignant melanoma, and the controversial effectiveness of photocoagulation in the treatment of malignant melanoma, makes necessary the reevaluation of light therapy in the treatment of small malignant melanomas.
