*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.
Freckled iris with iris nevus
According to Yanoff and Fine in their Ocular Pathology an iris freckle is caused by increased pigmentation of anterior border layer melanocytes without increased number of melanocytes. An iris nevus results from an increased number of atypical but benign-appearing melanocytes, i.e. nevus cells with variable pigmentation. The darker, larger lesion at 5 o'clock that extends from the pupil margin out over the pars pupillaris appears to be a nevus.
