In a retrospective study, 50 (8.2%) of 610 patients with malignant melanoma of the ciliary body or choroid had extrascleral extension. Of 46 patients for whom follow-up data were available, 24 (52%) survived five years, 20 (42%) survived ten years, and 17 (37%) survived 15 years. Factors that seemed to affect survival significantly included intraocular tumor size and extraocular tumor size and location. Our observations did not support the role of primary exenteration. Five patients (11%) with extrascleral extension had orbital recurrences and all died within 31 months of surgery regardless of treatment.
