Abstract Details

Purpose:

To present a new surgical technique ` Double Flap Method` which would reduce the risk of Ahmed Glaucoma Valve (AGV) implantation related hypertensive phase (HP) in patients undergoing AGV FP7 model for refractory neovascular glaucoma (NVG).

Setting:

Shri Ganesh Vinayak Eye Hospital, Raipur, India

Methods:

14 eyes of adult patients with refractory NVG underwent combined AGV implantation with trabeculectomy with releasable suture. Instead of using graft to cover the tube, partial thickness scleral flap was made. Trabeculectomy with releasable suture ensured intraocular pressure control in initial 6 months. Use of releasable suture reduced the risk of shallow anterior chamber or hypotony due to overfiltration.

Results:

None of the cases developed hypertensive phase in our series. 2 cases (14.3%) developed hypotony which was successfully managed conservatively. IOP reduced significantly from preoperative levels (p<0.001).

Conclusions:

Use of Double flap method will reduce the risk of hypertensive phase without increasing complications. Larger studies and longer follow-up periods are required to confirm our findings.
