Purpose: To clarify clinical features of patients with uveal melanoma. Method: We analyzed 125 eyes of 125 patients diagnosed as uveal melanoma from 1992 to 2014 retrospectively. Results: The mean age of the patients at the time of diagnosis was 58.1±14.4 years. Tumors were originated in the choroid (93%), ciliary body (4%) and iris (3%). The main reasons leading to diagnosis included decreased vision (27%), visual field loss (17%), and no significant symptoms (16%). Average tumor size of the choroidal melanoma was 10.4 mm in largest basal diameter and 7.2 mm in height. Treatment included enucleation of eyeball (53 cases), local resection of the tumor (4 cases), heavy particle beam therapy (18 cases), and brachytherapy (4 cases). Extraocular metastasis was detected in 22% of the patients, and 89% of them died within 5 years. Five-year survival rate was 20% in 6 cases (13.6%) in whom histopathologic studies revealed extrascleral invasions. Conclusions: Prognosis of patients with metastatic uveal melanoma is extremely poor. Early diagnosis and treatment, and establishment of follow-up system after local treatment are critical. Further development and dissemination of novel treatment for metastatic melanoma is desired.
