AIM:To evaluate the therapeutic effect of selective laser trabeculoplasty (SLT) for glaucoma evolutum.·METHODS:Totally 36 eyes diagnosed with glaucoma evolutum were treated with SLT. Intraocular pressure (IOP),visual acuity,C/D,visual field and the change of drugs were observed at different time.·RESULTS:The IOP changed from 24.44±5.55mmHg preoperatively to 24.22±6.32mmHg at the postoperative hour 1; in the postoperative day 1,week 1,month 1,2,3,6,9 and 12,the IOP decreased and showed statistical significance. The C/D changed from 0.75±0.16 preoperatively to 0.76±0.14 at the postoperative month 6 and showed no statistical significance. The number of drugs decreased in the postoperative month 6 and showed statistical significance,but at the postoperative month 9,12 the number of drugs increased and showed no statistical significance. There was no significant difference in visual acuity and visual field between the preoperation and postoperation.·CONCLUSION:SLT is an effective method for decreasing the IOP in glaucoma evolutum.
