A CASE OF HYPERPLASIA OF THE EPITHELIUM OF THE CILIARY PROCESSES

Abstract

According to Collins, increased proliferative activity of the epithelial lining of the ciliary body gives rise to small innocent growths at times met with in the eyes of elderly persons. Their presence is discovered only on histologic examination. In the case here reported and in one other case recorded by Coates such a growth attained sufficient size to lead to the clinical diagnosis of a tumor of the ciliary body.
