THE occurrence of neovascularization and the appearance of spontaneous hemorrhages in the anterior chamber in iris melanomas are well known.1-4 The vascularization may even give a hemangiomatous aspect to the melanoma, but histological examination will usually reveal the vascular lesion to be secondary. Sometimes, however, it appears to be difficult to differentiate between both conditions. The following case will show that eventually much experience is needed to make a decision.
Report of a Case
—The patient, a man, born in 1893, was examined ophthalmologically in 1956. In the left eye, a rather large iris melanoma was seen, which had caused an ectropion of the pupil. As this tumor, according to the patient, existed already for more than 25 years, no operation was performed. The patient was advised to visit the ophthalmologist regularly for inspection of his lesion. In 1963 there still was no visible change of the tumor.
