Sinus trabeculectomy: Preliminary results of 100 operations

Abstract

The new techniques of simple and filtering sinus trabeculectomy are described. Both are based on the removal of a piece of deep scleral tissue including Schlemm's canal and the trabecular meshwork, the wound being closed with a scleral flap. If filtering sinus trabeculectomy is performed, a small portion of the external scleral flap is excised. In 96 per cent. of 100 eyes so treated, the intraocular pressure was controlled by surgery alone, and the rate of complications was low. The results were stable in 57 of 59 eyes observed 3 to 12 months after surgery. Indications for these operations are discussed.
