The iris naevus (Cogan-Reese) syndrome: Light and electron microscopic observations

Abstract

The light and electron microscopic findings in an eye enucleated from a 38-year-old woman with iris naevus (Cogan-Reese) syndrome are presented. The clinical manifestations of this disease, namely, iridic stromal matting, iridic nodule formation, and unilateral angle-closure glaucoma, appear to be secondary to an endothelial membrane on the anterior surface of the iris. The iris naevus syndrome is now thought to represent one end of the clinical spectrum of an iridocorneal endothelial syndrome which also includes those clinical entities classified previously as Chandler's syndrome and essential iris atrophy.
