The Effect of Contact Transscleral Nd:YAG Laser C yclophotocoagulation in Refractory Glaucoma

ABSTRACT

We observed the change of intraocular pressure(IOP)and the complications after contact transscleral cyclophotocoagulation with NeodymiumYAG (NdYAG)laser for the refractory glaucoma patients. Refractory glaucoma in twenty eyes was treated with contact transscleral continuous-wave NdYAG laser cyclophotocoagulation with a sapphire-tipped probe. Using 7W of power for 0.7 seconds with 32 applications and intraocular pressure(IOP) was measured at 1 day, 1 week, 1 month, 2 months, 3 months, 4 months, 5 months and 6 months, postoperatively. The intraocular pressure(IOP)decreasing rate was 62% and the success rate was 60%at 6 months postoperatively. It is suggested that contact transscleral cyclophotocoagulation with NdYAG laser is useful in lowering IOP in refractory glaucoma patients.
