The Effect of Transscleral Diode Laser Cyclophotocoagulation in Refractory Glaucoma

ABSTRACT

The purpose of this study was to validate the efficacy of transscleral diode laser cyclophotocoagulation (CPC)procedure in refractory glaucoma cases for which conventional medical or surgical filtering procedures had failed or were thought to have a poor likelihood of success. Thirty-eight eyes of 38 consecutive patients with refractory glaucoma received transscleral diode CPC. Patients were followed for a mean of 5.5 months. We reviewed available data at preoperative state and at 1 day, 1week, 1 month, 2 months and 4 months postoperatively. Data analyzed were visual acuity, intraocular pressure(IOP)and postoperative complications. There was a statistically significant decrease in IOP at postoperative 1day, 1 week, 1 month, 2 months and 4 months compared with preoperative IOP. Postoperative complications were hyphema in 4 eyes and fibrinousuveitis in 1 eye but all of these complications were controlled with medical treatment. We concluded that transscleral diode CPC could be a good treatment proce-dure for the IOP control in refractory glaucoma cases.
