*Dr. Caccamise has very generously shared his images of patients taken while operating during the "eye season" in rural India as well as those from his private practice during the 1960's and 1970's. Many of his images are significant for their historical perspective and for techniques and conditions seen in settings in undeveloped areas.
At 3 o'clock, the pigment epithelium of the iris has been pulled over the pupil margin onto the anterior surface of the iris. The dark brown patch that covers the pars pupillaris and then ends at the iris frill at 3 o'clock is the patch of ectropion uveae.
Extropion uveae is "a rare, nonprogressive anomaly characterized by the presence of iris pigment epithelium on the anterior surface of the iris stroma, often associated with neurofibromatosis and occasionally with other ocular anomalies."(source: Ritch R, Forbes M, Hetherington J Jr, Harrison R, Podos SM.
