EyeRounds Online Atlas of Ophthalmology

*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.
Congenital coloboma of the iris with pyriform cornea
The pyriform nature with pointing inferiorly should immediately suggest a congenital coloboma of the iris inferiorly at the location of the fetal fissure. The coloboma in this eye cannot be seen in this photograph because the iris is so dark brown. Fundus examination at times may reveal varying extension of the uveal defect posteriorly - even to the point of including the optic nerve. The vertical pigmented line a few mms from the cornea is due to pigmentation at the points of normal bloodvessel perforation of the sclera in this heavily pigmented patient. Patients with coloboma of the iris should be examined carefully for other developmental defects.
