Pars plana Ahmed glaucoma valve implantation with triamcinolone-assisted vitrectomy in refractory glaucomas.

ABSTRACT

Glaucoma drainage devices are an option in refractory glaucomas for control of intraocular pressure (IOP). We evaluated the outcome of pars plana Ahmed glaucoma valve along with triamcinolone-assisted vitrectomy in 11 eyes with uncontrolled IOP on maximum tolerable antiglaucoma therapy. The mean preoperative IOP of 33.64 ± 5.99 (range 26 to 44 mmHg) decreased to 17.09 ± 2.26 (range 14 to 20 mmHg) and 17.45 ± 1.81mm of Hg (range 14 to 24 mmHg) at 6 and 12 months following surgery. The mean number of antiglaucoma medications decreased from 3.27 ± 0.05 to 0.64 ± 0.67 and 0.55 ± 0.6 at 6 and 12 months following surgery.
