The Prognosis of Primary Tumors of the Iris Treated by Iridectomy

Abstract
Over the years it has become increasingly evident that tumors of the iris should not be lumped with those of the ciliary body and choroid. They present entirely different problems in clinical diagnosis and surgical management, and there is mounting evidence to support the belief that biologically they may be different tumors. Progress in the study of these tumors has been slow, for they are not common, and a large volume of material with many years of follow-up is necessary for the accumulation of a series of cases from which lessons can be learned. Reese,1for example, stated that at the Institute of Ophthalmology, in New York. 271 malignant melanomas of the uvea included only 23 that were primary in the iris. More recently, Duke and Dunn2reviewed the primary tumors of the iris in the pathology laboratory of the Wilmer Institute and were able to report only
