Trabeculectomy for Acute Primary Angle-Closure
摘要
Purpose: To analyze the results of trabeculectomy and the effect of anti-metabolites in cases of acute primary angle closure (APAC) with failed medical control and laser iridotomy. Method: In this study, 29 first-time APAC cases who received trabeculec-tomy between March 1, 1999 and June 30, 2008 were reviewed retrospectively. The cases that had cataract surgery within 6 months and a follow-up period of less than 6 months were excluded. The surgical outcome and complications were assessed according to the record including the intraocular pressure (IOP) at post-operative 2 weeks, and 1, 2, 3, 6, 9, and 12 months, as well as at the last visit to the clinic. Result: Final IOP was controlled to less than 21 mmHg without medications in 22 patients (75.9%). IOP was controlled to less than 21 mmHg with medication in 3 patients (10.3%). Four patients (13.8%) who required further glaucoma surgery were considered as failures. Mitomycin C (MMC) was used in 8 patients (27.6%). There was no significant difference between the MMC (+) group and the MMC (-) group in the mean IOPs at all follow-up months. Only one case encountered anterior chamber collapse (3.4%) Conclusion : Trabeculectomy has a favorable outcome in APAC with failed medical control and laser iridotomy.
