Clinical observation of compound trabeculectomy in primary angle-closure glaucoma with persistent high intraocular pressure

Objeetive To investigate the clinical effects of compound trabeculectomy for primary angle-closure glaucoma with persistent high intraocular pressure.Methods 60 eyes(60 cases)of primary angle-closure glaucoma with persistent high intraocular pressure were randomly divided into two groups,38 cases (38 eyes)underwent compound trabeculectomy was observe group and 22 cases(22 eyes)underwent trabeculectomy as control to compare the postoperative intraocular pressure(IOP),filtration,me depth of anterior chamber and Postoperative complications between the two groups.Results 60 eyes was successful.In the follow-up of 8～15 months.The incidence rate of shllow anterior chamber in observe group and control group were 5.3%and 22.7%respectively(P＜0.05)on the first day of postoperation.Eight months late,the rate of intraocular pressure from 6 to 21 mmHg in observe group and control group were 89.5%and 68.2%respectively (P＜0.05).functional filtering bubles were 86.9%and 63.6%respectively(P＜O.05).Conclusion Compound trabeculectomy is efective and safe for primary angle-closure glaucoma with persistent high intraocular pressure Key words: Compound trabeculectomy; Glaucoma; Persistent high intraocular pressure
