Abstract Details

Purpose:

To evaluate results of second Ahmed Glaucoma Valve (AGV) implantation in eye with refractory Neovascular Glaucoma (NVG) with failed primary AGV.

Setting:

Tertiary eye care institute in central India

Methods:

17 adult eyes with NVG underwent second AGV implantation when Intra-ocular pressures (IOP) were not controlled after first AGV implantation. This was a retrospective case series. Minimum follow-up of 1 year was considered. Success was defined as IOP >5mm Hg and ≤21 mm Hg. Pre and post surgery IOP measurements, number of antiglaucoma medications and complications were assessed.

Results:

Mean IOP reduced from 36.94 +/- 4.9 mmHg to 16.6 +/- 2.3 mm post-operatively (p < 0.001). Percentage mean reduction in IOP from baseline was (57.54 +/-9.98 %). Hyphema was the most common postoperative complication (35.3%) followed by shallow AC and corneal edema (23.5% each). Number of antiglaucoma medications required postoperatively was (1.40 +/-1.17). 2 eyes (11.8%) had failure at 1 year follow-up.

Conclusions:

In refractory NVG patients with failed AGV, implantation of second AGV results in good IOP control and reduced need for AGM.
