Uveal melanoma is the most common intraocular malignancy and arises from melanocytes in the iris (anterior), ciliary body, or choroid (posterior). Iris melanomas have the best prognosis, whereas melanomas of the ciliary body have the least favourable prognosis. Most uveal tract melanomas originate in the choroid while the iris is the least common. The typical choroidal melanoma is a brown, elevated, dome-shaped sub retinal mass. The degree of pigmentation ranges from dark brown to totally amelanotic. Melanomas of the choroid generally are more malignant. Males have a higher incidence than females. UM is diagnosed mostly at older ages, with a progressively rising, age-specific, incidence rate that peaks near the age of 70 years. Most Uveal melanomas are initially completely asymptomatic. As the tumour enlarges, it may cause distortion of the pupil (iris melanoma), blurred vision (Ciliary body melanoma), or markedly decreased visual acuity caused by secondary retinal detachment (choroidal melanoma). Serous detachment of the retina may occur.
