Abstract:
Objective To observe the changes of chamber angle after phacoemulsification and goniosynechialysis(Phaco-GSL) for primary angle-closure glaucoma(PACG) with cataract,and evaluate the therapeutic effect of Phaco-GSL on PACG.Methods Fifty patients(50 eyes) with PACG and cataract were treated in our hospital,and peripheral anterior synechiae(PAS) of all their affected eyes was over 180 degrees.By single blind method,they were randomly divided into Phaco-GSL treated group(treatment group) and single phacoemulsification group(control group).The chamber angles were checked with gonioscopy 1 and 3 months after operation,and intraocular pressure(IOP) of 50 eyes was examined 1 week,1 and 3 months after operation.Results ①In group A,the rate that chamber angles reopened were over 180 degrees was 100%,and the chamber angles were wide,trabecular meshwork visible in 5 cases(20%),scleral spur visible in 12 cases(48%) and ciliary band visible in 8 cases(32%).In group B,the chamber angles reopened over 180 degrees were in 12 cases(48%) 1 month after operation and PAS reoccurred in 2 affected eyes.The effect of reopening chamber angle in group A was better than that in group B(P180 degrees can be treated by cataract extraction combined with goniosynechialysis,while trabeculectomy is not necessary.
