We describe a simple blow-back technique that can be used to confirm the patency of a peripheral iridectomy. Flow reversal is used to flush the iridectomy specimen onto the corneal surface to look for the presence of iris pigment epithelium in small basal iridectomies fashioned using a vitrector.

    Trabeculectomy performed without peripheral iridectomy appears to be as effective in lowering intraocular pressure as when performed with peripheral iridectomy, but it is a safer procedure, with a lower incidence of postoperative inflammation. It may be an advantage to avoid performing peripheral ir...
