Peripheral iridectomy, though a relatively minor procedure in intraocular surgery, has proven of utmost value in treatment of angle-closure glaucoma. Many different techniques for performing the operation have been and are being employed. Techniques vary in the use of a conjunctival flap, in making the incision, in suturing the wound, and in doing the iridectomy. Variations in technique concerning these points will be discussed and then the method of doing the operation will be presented which, after a trial of various techniques, the author now prefers.
The operation can be done without a conjunctival flap by making the incision in the peripheral cornea, but most surgeons feel that a conjunctival flap is desirable. The end result is probably the same whether the flap is limbus- or fornix-based. A limbus-based flap is somewhat in the way in making the incision and especially in placing sutures. The fornix-based flap retracts
