RESULTS: A total of 45 eyes from 45 patients were treated with the Ahmed glaucoma valve implant and its combination surgery. At a mean follow up of 9.7 months (range3～18months), the mean intraocular pressure was reduced from 36.8±12.3mmHg before the implant surgery to 18.0±4.5mmHg at the last follow up after surgery. The success rate was 87%.The best postoperative corrected visual acuity improved 16 eyes(35%).Transient postoperative hypotony and shallow anterior chamber occurred in 20% of cases.
