PURPOSE: In order to estimate the postoperative results of non-penetrating trabeculectomy (NPT), the success rate of postoperative intraocular pressure (IOP) and the clinical factors affecting postoperative IOP were evaluated. SUBJECTS AND METHODS: Thirty-two eyes of 32 primary open-angle glaucoma (POAG) patients who underwent NPT as the first filtering surgery were enrolled in the study. The authors evaluated postoperative IOP using the Kaplan-Meier method, a proportional hazard model, and multiple logistic analysis. RESULTS: 53.2% of all patients had an IOP of less than 16 mmHg without antiglaucoma medication, and 63.8% had an IOP of less than 16 mmHg with antiglaucoma medication 36 months postoperatively. The performance of Nd:YAG trabeculopuncture (YLT) was indicated as a significant factor affecting postoperative IOP by the proportional hazard model (p = 0.037). 72.2% of patients who did not undergo YLT had an IOP of less than 16 mmHg without antiglaucoma medication, and 36.5% who underwent YLT had a postoperative IOP of less than 16 mmHg. There was a significant difference between the both groups (log rank test, p = 0.045). Preoperative IOP with antiglaucoma medication was indicated as a significant factor affecting the performance of YLT by multiple logistic analysis. CONCLUSIONS: These results suggest that NPT may be useful to reduce the use of antiglaucoma medication in patients with POAG whose preoperative IOP is controllable with antiglaucoma medication.
