PURPOSE
To compare the short-term surgical outcomes of Ahmed glaucoma valve implant with a surface area between 96 mm2 and 184 mm2. METHODS: The outcomes of thirteen eyes of 13 patients with refractory glaucoma who had undergone 96 mm2-sized Ahmed glaucoma valve implantation were compared with those of 13 eyes of 13 patients with 184 mm2-sized Ahmed glaucoma valve implantation. RESULTS: Average age and preoperative intraocular pressure (IOP) were statistically indistinguishable between the two groups (p=0.54 and 0.40, respectively). Average follow-up period and final IOP were also statistically similar (p=0.15 and 1.00, respectively). Comparing the overall IOPs and the numbers of antiglaucoma medications, the IOP of postoperative day 1 with the 184 mm2-group was only relatively lower (p=0.07). The 2-year success rates were 18.0% for the 96 mm2-group and 69.2% for the 184 mm2-group (Ed-there is no respective comparison here) with Kaplan-Meier survival analysis (p=0.0018). The rates of complications and re-operation were similar between the two groups. CONCLUSIONS: The average postoperative IOPs were not statistically different between the two groups. However, the success rate was better in the 184 mm2-group than in the 96 mm2-group. |
