چکیده

Purpose. to compare laser peripheral iridotomy (lpi) with trabeculectomy as an initial treatment for primary angle-closure glaucoma (pacg) with peripheral anterior synechiae (pas) ≥ 6 clock hours. methods. patients were drawn from two randomized controlled trials. 38 eyes of 38 patients (pas ≥ 6 clock hours) were treated with lpi (group 1) while 111 eyes of 111 pacg patients (pas ≥ 6 clock hours) underwent primary trabeculectomy (group 2). all patients underwent a comprehensive ophthalmic examination at baseline and at postoperative visits and were followed up for a minimum of one year. results. group 2 had higher baseline iop (45.7 ± 14.8 mmhg versus 34.3 ± 14.3 mmhg) than group 1 and more clock hours of pas (10.4 ± 1.9 versus 9.0 ± 2.2). iops at all postoperative visits were significantly lower in group 2 than in group 1 (p=0.000). five eyes in group 1 required trabeculectomy. 17 of the 38 eyes in group 1 (44.7%) required iop-lowering medications as compared to seven of the 111 eyes in group 2 (6.3%). cataract progression was documented in 2 eyes (5.3%) in group 1 and 16 eyes (14.4%) in group 2. conclusions. primary trabeculectomy for pacg (pas ≥ 6 clock hours) is more effective than lpi in lowering iop. © 2017 yan yun chen et al.
