Overview
Common risk factors in the development of uveal melanoma are cutaneous and iris nevi, host pigmentation factors, and ultraviolet light exposure.
Risk Factors
Common risk factors in the development of uveal melanoma include:
- Cutaneous and iris nevi
- Atypical cutaneous nevi
- Common cutaneous nevi
- Cutaneous freckles
- Iris nevi
The risk of progression of iris nevi to melanoma at 5, 10, 15, and 20 years is 3, 4, 8, and 11 percent, respectively. Significant risks factors associated with an increased risk of transformation include younger age, inferior location, diffuse pigmentation, presence of blood in the lesion, ectropion, and a feathery margin.
- Choroidal nevi
Generally, choroidal melanoma arises in pigmented nevi. The risk of progression to melanoma at 5, 10, and 15 years is 9, 13, and 17 percent, respectively.[1]
- Host pigmentation factors
- Light eye color
- Fair skin color
- Propensity to sunburn
- Ultraviolet light exposure
