Summary

Bleb failure is reduced with Punch trabeculectomy procedure. Wide sclerostomy during surgery is wanted but controllable. This can be done with single securing suture, releasable sutures and topical intraoperative mitomycin-c. Average IOP without fluctuation (risk factor) can protect the optic nerve.

Detailed description

This is a prospective randomized study. Patients had uncontrolled glaucoma on maximum tolerated medical therapy including acetazolamide tablets were enrolled in this clinical trial and were randomized to tight flap technique group (group A) and loose flap technique group(group B). Randomization assigned 40 patients to group A and 40 patients to do group B. A total of 80 patients were enrolled in the Study between 2012 and 2014. During trabeculectomy, Trabecular meshwork and scleral lamellae were excised made an opening with the kelly scleral punch 1.0 mm 3-5 bites. At 12 o'clock 10/0 nylon monofilament stitch was used to close the apex of triangular scleral flap tightly and two releasable stitches were used at the sides of triangular scleral flap in group A. Fig-1 At 12 o'clock 10/0 nylon monofilament stitch was used to secure the edges of the flap at the apex of and two-four releasable stitches were used at the sides of triangular scleral flap in group B. The intraocular pressure and bleb morphology were followed for one year after surgery.
