Choroidal melanoma is a common intraocular malignancy among Caucasian adults. This serious and potentially lifethreatening lesion is associated with high rates of metastasis. This teaching case report describes an otherwise healthy young patient presenting with amelanotic choroidal melanoma. Differential diagnoses, symptoms, clinical findings, ancillary tests, treatment options and prognosis for amelanotic choroidal melanoma are discussed. Recognition of the clinical manifestations of choroidal melanoma leads to an early diagnosis and timely initiation of treatment. [ABSTRACT FROM AUTHOR]
