Cyclodialysis is performed less frequently than most other operations for glaucoma; however, in occasional cases, it offers the best hope for the preservation of vision so that continued studies are justified. In some of my patients, cyclodialysis has failed because the cleft made between the ciliary body and sclera has been closed by a forward ballooning of the peripheral iris against the trabecula and cornea. An invariable postoperative finding in these failures has been extensive iris adhesions spreading onto the cornea. Any degree of obstruction to the free flow of aqueous from the posterior into the anterior chamber would contribute to this forward displacement of the peripheral iris; therefore, it is essential to recognize such obstruction and to make a peripheral iridectomy at the time of the cyclodialysis.

Combined cyclodialysis and iridectomy is not a new procedure. Torok1 advocated it in 1923, but recommended two entirely separate incisions. Later,
