Malignant melanoma of the uveal tract is the most common primary intraocular malignant tumor in the adult population, with an annual incidence of approximately 6 cases per million per year [1]. The diagnosis of uveal melanoma has been aided by the use of indirect ophthalmoscopy and the judicious employment of ancillary studies such as fluorescein angi-ography, ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), radioactive phosphorus uptake test, and intraocular biopsy [2]. Immunological techniques using monoclonal antibodies and immunoscintigraphy have also been evaluated [3]. The traditional form of treatment, enucleation, has been challenged. It has even been suggested that enucleation may actually worsen the patient's prognosis by promoting the dissemination of tumor cells or disrupting the patient's immune mechanisms at the time of surgery [4]. In recent years, alternative methods of treatment, including periodic observation, photocoagulation, radiotherapy, and local resection, have been used more frequently to manage poste-rior uveal melanoma [1–3].Approximately 40% of the patients with uveal melanoma who undergo enucleation die within 10 years of metastatic melanoma, usually to the liver [5]. Despite this, clinically evident metastatic disease at the time of initial presentation of the primary tumor is uncommon, being detected in only 1 to 2% of patients using conventional methods such as serum liver enzymes and liver scans [2]. These findings suggest that subclinical metastatic disease may be more common than is currently suspected. For example, in one investigation, pretreatment serum liver enzymes and liver scans were abnormal in 12% of the patients who later died of metastatic melanoma [6]. Clinically, diffuse hepatic metastasis of uveal melanoma has been documented surgically in a patient who had concurrent normal serum liver
