Abstract:
Clinical identification of tapioca melanoma of the iris is important because its medical treatment may differ from that of other malignant iris melanomas. The characteristic iris nodules must be differentiated from granulomatous uveitis, metastases, and Lisch nodules (neurofibromatosis). We will discuss the anterior segment findings, secondary glaucoma, and fluorescein iris angiographic and histopathologic data from two patients, one with a single nodular type and one with a seeding type of tapioca melanoma of the iris.
