Abstract
Objective:To study the application of ultrasonic biological microscope (ultrasound biomicroscopy, UBM) observation of primary angle-closure glaucoma (PACG) surrounding the traditional iris resection before and atfer the change of anterior chamber angle.Methods: Analysis of our hospital from June 2013 to January 2015 were diagnosed angle-closure glaucoma 26 patients (37 eyes), 7 patients were male, female 19 cases, aged 42~76, the primary closed-angle glaucoma preclinical 23 eyes, 8 eyes prodromal stage, intermittent period 6 eyes, all around the iris resection. Analysis of postoperative cure rate; preoperative and postoperative application of UBM, the measurement of anterior chamber, compare the preoperative postoperative trabecular iris angle, corner open distance; at the same time observe the iris shape change.Results:1) In 23 cases were cured and 37 eyes of 97.4% (37/38), 1 case ineffective 1 eye, 2.6% (1/38); 2) before and atfer treatment of trabecular iris angle, theanterior chamber angle open distance 500 (t=2.155, 2.172;P<0.05); 3) after resection of the iris surrounding the iris root tissue away from the trabecular meshwork, adhesion corner radius reduced.Conclusion:ultrasound biomicroscope (UBM) were observed before and atfer resection of the primary closed-angle glaucoma peripheral iris anterior chamber angle changes, can observe the disease atfer the situation, determine the trabecular iris angle, anterior chamber angle open distance, postoperative iris change situation, indicates that iris surrounding clinical resection is an effective method for the prevention and treatment of angle-closure glaucoma.关键词
