Microsurgery of choroidal melanoma--surgical techniques of local excision.

Six cases of malignant choroidal melanoma were treated by microsurgical excision under hypotensive anaesthesia with follow-up periods varying from four months to four years. This paper presents the case for local excision of malignant choroidal melanoma in the light of the current controversy surrounding the management and natural history of choroidal melanoma. The indications for surgery, techniques, and results are described. Vision was preserved best in tumours with diameters of less than 10 mm. No deaths and no evidence of extraocular recurrence occurred.
