Objective To exploare the value of transscleral diode laser cyclophotocoagulation in the treatment of refractory glaucoma． Methods Using transscleral semiconductor diode laser cyclophtotocoagulation( energy 1． 5 － 2． 0W，time 1s，range 180 － 360°，count 12 － 30) to treat 53 eyes with refractory glaucomea． Results Follow-up was 13 － 21 months． IOP decreased from 48． 7 ± 8． 5mmHg ( 33． 2 － 64． 9mmHg) of pretreatment to 19． 3 ± 7． 6mmHg( 6． 8 － 32． 7mmHg) of post-treatment，and there was significant reduction in mean IOP( P ＜ 0． 01) ． IOP fell more than 30% in 41 cases． The success rate of surgery was 77． 3%，and eye pain relief rate was 92． 5%． Uveitis and hyphema were the major complications． Conclusion Transscleral semiconductor diode laser cyclophotocoagulation is an efficient，safe and repeatable treatment for refractory glaucoma with less complication．
