Figure 3

(a) A peripheral iridectomy (PI) is done with curved Vannas scissors by retracting basal iris through the tunnel with nontoothed forceps while the assistant retracts the conjunctiva for visualization. (b) Viscoelastic is washed out. (c) Patency of the tunnel is checked by irrigating the anterior chamber with balanced salt solution and looking for bleb formation. The conjunctival incision is then sutured with a running 10-0 nylon suture. (d) The bleb is seen lifted after side port irrigation.
