【Abstract】 Objective To prove the effectiveness of peripheral iridectomy with YAG laser in preventing attack of primary angle closure glaucoma.Methods 30 eyes(30 cases)with no attacked primary angle closure glaucoma were selected to receive peripheral iridectomy with Nd:YAG laser on the iris crypt of mid to outer one third peripheral iris (at 1∶00 of 5∶00 clock). Results The follow-up period ranged from 1 to 12 months.No attacks of acute angle closure glaucoma were observed with one time treatment,the iris perforation rate was 86.7%;while with twice procedure,the iris perforation rate was 100%.Conclusions Peripheral iridectomy with YAG laser is a economical,safe and painless method in preventing attack of acute angle closure glaucoma.更多还原
