Iris melanomas (seen most frequently in blue irides) account for only a small portion of uveal tumors (<10%). They are inferiorly located due to sun exposure and may distort the pupil. Iris melanomas rarely metastasize (3-5%) because visibility typically leads to early detection. Satellite lesions can be seen. Increased IOP is common with seeding of tumor cells into the trabecular meshwork.
Differential diagnoses include iris nevi, Lisch nodules, Koeppe and Busacca nodules.
