الملخص EN

urpose: A combination ofhypotony.flat anterior chamber and choroidal detachment is the most common complications afterfiltering surgery.

The purpose of this study is to present a new modification in standard trabeculectomy technique to reduce such complications.

Patients and Methods: 17 patients (17 eyes) with uncontrolled primary open angle and narrow angle glaucoma were operated by this new procedure.

All cases had a previous trabeculectomy in the other eye with post-operative flat AC.

Results: The mean preoperative IOP with hypotensive medications was 32 mmHg and the mean postoperative IOP was 14 mmHg after 12 months postoperative follow up.

The success rate was 82 % with IOP below 17 mmHg at end of follow-up period.

The number of postoperative flat AC was Zero.

Conclusion: This new modification is a safe, simple, rapid and highly effective in prevention of post-operative flat AC, because it respects the anatomy and physiology of the angle structure more than conventional trabeculectomy technique.
