An Effects of Contact Transscleral Diode Laser Cyclophotocoagulation in Refractory Glaucoma Patients

ABSTRACT

We evaluated the the effect and the suitable level of ciliary ablation with diode laser contact transscleral cyclophotocoagulation[TSCPC] in eyes with refractory glaucoma. Fourteen eyes were treated with contact transscleral cyclophotocoagulation on 180 degree[Group 1, 6 eyes], and 270 degree[Group 2, 8 eyes], and the intraocular pressure was measured at 1 day, 1 week, 1 month, 3 month, postoperatively. The mean preoperative intraocular pressure was 46.8+/-14.3 mmHg and the mean intraocular pressure at last examination was 29.5+/-13.2 mmHg. Success rate was defined as follows[1] more than 20% intraocular pressure reduction from baseline, [2] less than 21 mmHg at final examination. Based on the definition of success 1, the success rate was 66.6% in group 1 and 87.5% in group 2. Based on the definition of success 2, the success rate was 50% in both group. It suggests that contact transscleral cyclophotocoagulation with diode laser is useful in lowering IOP in refractory glaucoma patients and the treatment is also effective with ablation of 180 degree area in refractory glaucoma patients.
