Discriminator and Diagnostic Features for Choroidal Malignant Melanoma and Choroidal Nevus

Abstract

Choroidal nevus and choroidal malignant melanoma, especially when they are small in size, may have similar ophthalmoscopic appearance. Additionally, though rarely, choroidal nevi may convert to malignant melanomas over several years. Early detection of a small choroidal malignant melanomas presents the risk of growth, and metastasis is extremely critical for the preservation of both vision and eye. Currently, the usage of the mnemonic TFSOM-HHD has been suggested to find small ocular melanomas using helpful hints daily. In this review, we aim to provide the main discriminator and diagnostic features for choroidal malignant melanoma and choroidal nevus.
