Long-term clinical effectiveness of reformed nonperforating trabeculectomy / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM: To investigate the clinical effectiveness of reformed nonperforating trabeculectomy (NPT) in the patients with primary glaucoma.METHODS: 30 eyes of 21 patients with primary glaucoma patients underwent reformed NPT, in which 1.0mm3.0mm out layer of trabecular meshwork with Schlemm's canal was excised, but the innermost tissue was reserved. The clinical effectiveness was observed with short-term follow-up (1wk;1,6mo) and the long-term follow-up (1a and over, 10a the longest).RESULTS: The intraocular pressure (IOP) was controlled in 28 eyes (93%) without anti-glaucoma medicine during short-term follow-up, and in 27 eyes (90%)for long-term ones. There were no serious post-operative complications in all cases.CONCLUSION: The elevated IOP in patients with primary glaucoma can be effectively reduced by reformed NPT during short-term and long-term follow-up. The post-operative complications are much less because of no intra-operative penetration of the anterior chamber. The reformed NPT is an ideal surgical procedure for primary glaucoma.
