Clinical observation of trabeculectomy under the keeping of anterior chamber

Objective To explore the effect of trabeculectomy under the keeping of anterior chamber.Methods 77 eyes(77 patients) with primary angle-closure glaucoma were divided into two groups:41 eyes(32 patients) treated by normal trabeculectomy after being infused sodium hyaluronate into anterior chamber,47 eyes (45 patients) underwent normal trabeculectomy were used as control.Results The percentage of shallow anterior chamber was 12.20%(4/41) in the group with sodium hyaluronate and 31.91%(15/47) in normal trabeculectomy.There was significant difference between two groups( P0.05) .The successful rate of operation was 97.56%(40/41) in the group with sodium hyaluronate and 89.36%(42/47) in the group of normal trabeculectomy respectively,no significant difference between two groups( P 0.05) . Conclusion Trabeculectomy under keeping anterior chamber may decrease the occurrence of postoperative shallow anterior chamber.
