PURPOSE: The authors studied the usefulness and issues in recent procedures for nonpenetrating trabeculectomy (NPT) for patients with glaucoma. MATERIAL AND METHODS: NPT was performed in 51 eyes of 43 patients and follow-up was continued for at least three months after NPT. Results were evaluated by Kaplan-Meier life-table analysis. NPT was considered to have failed if reoperation or systemic medication was required or postoperative intraocular pressure (IOP) was more than 22 mmHg or decreased less than 20% compared to preoperative IOP. RESULTS: After an average 8.4 ± 4.4 months of follow-up, the final success rate for NPT was 66.7%. IOP decreased from a mean of 23.1 ± 7.6 mmHg preoperatively to a final mean of 12.7 ± 2.8 mmHg postoperatively. In general, IOP decreased to a low of less than 10 mmHg and then increased slowly for up to one year after the operation. Subconjunctival injection of 5-fluorouracil was needed after surgery in 25 of the 47 eyes. Nd:YAG laser trabeculopuncture was performed in 11 eyes. Even in the 31 cases that were considered successful, patients continued ocular massage for 27 eyes in the postoperative period. Four of six cases that required additional glaucoma surgery had histories of intraocular surgery before NPT. CONCLUSIONS: Because aqueous filtration may be slow after NPT, we should beware of gradual conjunctival scarring in the filtering bleb. Not only modifications in surgical technique but also management of additional treatments in the postoperative period are important for the success of NPT. LA: Japanese
