Cysts of the iris are usually a late complication of cataract surgery. They may occur spontaneously. Epithelial cysts of the anterior chamber have been a rare but dreaded late complication of cataract surgery. Treatment of both types has always been a problem. Surgical excision has usually offered the most hope. In those cysts too large for surgery, use of x-rays and chemotherapy were sometimes successful. With the epithelial cyst of the anterior chamber, none of these methods was of much value and the eye was usually lost.
Vail,1 in 1953, reported four cases of iris cysts in which treatment by diathermy coagulation had been successful. He also reviewed the surgical, x-ray, and chemical treatment and pointed out some of the difficulties and failures of these methods.
Kirby,* in his discussion of Vail's paper, reported 10 cases of iris cyst treated successfully with tincture of iodine. Thilliez,3 in 1908,
