Abstract Purpose:To examine clinical outcomes of the pars plana Ahmed glaucoma valve implantation for refractory glaucoma.

Cases and Method:Medical records were reviewed retrospectively for 60 eyes of 50 patients(63.6±12.9 years of age)who had received the Ahmed glaucoma valve for refractory glaucoma from November 2016 to November 2019. As for the type of glaucoma, there were 30 cases of secondary glaucoma, 21 cases of neovascular glaucoma, and 9 cases of primary open angle glaucoma. Implant tubes were inserted into the vitreous cavity in all cases.

Results:Intraocular pressure(IOP)significantly reduced from 34.2±13.3 mmHg before surgery to 17.3±7.1 mmHg in 1 month, 15.0±5.3 mmHg in 3 months, 14.6±5.9 mmHg in 6 months and 15.3±4.9 mmHg in 12 months after surgery(p<0.0001). Postoperative complications were vitreous hemorrhages(16 eyes), choroidal detachments(10 eyes), hyphema(5 eyes)and hypotonic maculopathy, retinal detachment, subchoroidal hemorrhage, exposure of the plate, and endophthalmitis(1 eye). The treatment was reoperation in five eyes, anterior chamber irrigation in two eyes, vitrectomy in one eye, choroidal tapping in one eye, removal of the plate in one eye, and evisceration in one eye.

Conclusion:Ahmed glaucoma valve implantation was effective for refractory glaucoma by providing significant reduction of postoperative IOP continuously for 1 year, but clinicians need to be careful of complications after surgery.
