PURPOSE: To report the efficacy and safety of Ahmed glaucoma valve (AGV) insertion into the ciliary sulcus in pseudophakic/aphakic patients. PATIENTS AND METHODS: A chart review was done on patients with uncontrolled glaucoma, who underwent AGV implantation with tube inserted into the ciliary sulcus. Baseline intraocular pressure (IOP) and number of medications were compared with that of postoperative follow-up visits. Surgical success was defined as last IOP <21 mm Hg and 20% reduction in IOP, without further surgery for complications or glaucoma control, and without loss of light perception. Postoperative complications were recorded. RESULTS: Twenty-three eyes of 23 patients were recruited with the mean follow-up of 9 months (range, 3 to 24 mo). The mean (SD) age of patients was 49.9 (16.9) years (range, 22 to 80 years). The mean (SD) IOP (mm Hg) was reduced from 37.9 (12.4) before surgery to 16.2 (3.6) at the last follow-up visit (P<0.001). The mean (SD) number of medications was reduced from 3.3 (0.9) preoperatively to 1 (1.1) at the last follow-up (P<0.001). Success rate was 18/23 (78.6%). Complications included endophthalmitis in 1 eye, tube exposure in 1 diabetic patient, and vitreous tube occlusion in 1 eye. No case of corneal decompensation or graft failure was seen during follow-up. CONCLUSIONS: Ciliary sulcus placement of the tube of AGV effectively reduces IOP and medication use in short term. It has the potential to lower corneal complications of anterior chamber tube insertion and avoids the need for pars plana vitrectomy and tube insertion in patients at higher risk of corneal decompensation.
