Uveal melanoma is the most common primary malignancy of the eye in Caucasian adults, of which choroidal melanoma is the most common subtype.1 Ciliary body melanoma is a rare tumour seen in 1 out of 10 cases of all intraocular melanomas with an average age of 55 to 62 years.2, 3 Uveal melanoma arises from atypical melanocytes present in iris, ciliary body and choroid, although each tumour has some particular characteristics depending on its location and structure. Because of the continuous contractions of the ciliary muscle and rich vascularization of the ciliary body, metastasis is faster in ciliary body melanoma.2 Vascular metastasis leads to impairment of other organs which is the main cause of death among ciliary body melanoma patients with 10 year mortality rate being 30-50%.2 Ciliary body melanoma has the worst prognosis of all intraocular tumours due to early hematogenous metastasis which are frequently seen in the first year after diagnosis.
