Melanoma is the most common primary eye malignancy in adults and the eye is the second most common site for melanoma following the skin1. Eye melanomas are best described according to the anatomical location within the eye, as they differ in clinical presentation and behaviour, epidemiology, risk factors, genetic involvement, management, metastatic potential and prognosis. There are two major subtypes: uveal melanoma (comprising iris, ciliary body and choroidal melanoma) and conjunctival melanoma. Ciliary body and choroidal melanoma are frequently described together, collectively referred to as posterior uveal melanoma, while iris melanoma is described separately due to recognition of its more favourable prognosis compared with other eye melanomas.
