ABSTRACT

?AlM To evaluate the long - term effects of laser peripheral iridectomy ( LPl ) and trabeculectomy in treating early chronic angle-closure glaucoma. ?METHODS: Ninety-eight patients (102 eyes) with early chronic primary angle-closure glaucoma were randomly divided into two groups. Group A of 50 patients (54 eyes) was treated with LPl and group B of 48 patients (48 eyes) with trabeculectomy. After 3 - 8y of follow - up observation, comparison would be made from the perspectives of postoperative eyesight, intraocular pressure, anterior chamber angle, visual field and cup/disc ratio ( C/D) . ?RESULTS:ln group A, 24 eyes with eyesight declining, 22 eyes with theintraocular pressure>21mmHg (1mmHg=0. 133kPa), 21 eyes with chamber angle synechia >180o, 21 eyes with visual field narrowed, 21 eyes with C/D ratio enlarged. The results of group B for the same items were 10, 5, 4, 4, 4 eyes respectively. The comparative difference was statistically significant (P ?CONCLUSlONGood effects will be achieved for early-stage chronic angle - closure glaucoma with surgical method. Trabeculectomy is obviously better than LPl for the long-term effects.
