PURPOSE: The authors evaluated the results of non-penetrating trabeculectomy (NPT) in patients with primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG). METHODS: Intraocular pressure (IOP) and the occurrence of complications were recorded for at least three months after surgery in eyes that underwent non-penetrating trabeculectomy (NPT, 31 eyes of 31 patients) and penetrating trabeculectomy (PT, 38 eyes of 38 patients) as the first surgery for NTG or POAG. IOP was evaluated using Kaplan-Meier's life-table analysis. RESULTS: In the NPT group, average preoperative intraocular pressure (IOP) of 21.6 ± 7.5 mmHg, was decreased to 13.5 ± 2.9 mmHg after an average of 8.8 ± 3.9 months of follow-up. PT reduced the average IOP from 19.6 ± 3.4 mmHg to 12.4 ± 3.4 mmHg at 10.4 ± 4.1 months after the surgery. Final results were successful in 23 eyes with NPT (66.7%) and in 31 eyes with PT (8.1. 6%). NPT and PT proved to be not significantly different in reducing IOP or complications when performed on eyes with POAG. However, NPT was significantly less effective than PT when performed on eyes with NTG. Complications were fewer with NPT than with PT. CONCLUSIONS: In cases of NPT for eyes with NTG, Nd:YAG laser should be considered trabeculopuncture, even in the early postoperative period to obtain better control of IOP. LA: Japanese
