Semiconductor Laser Transscleral Cyclophotocoagulation in Treatment of Refractory Glaucoma

Objective To observe transscleral diode laser photocoagulation(DL Tscpc) treatment of refractory glaucoma.Methods Totally 52 eyes with refractory glaucoma with 810nm wavelength laser energy 1.5~2.5W,scleral cyclophotocoagulation postoperative follow-up observation and record intraocular pressure,visual acuity,eye symptoms and complications,follow-up time over the 36month.Results Before treatment,mean IOP in 52 eyes(54.12±1.75) mm Hg,mean IOP of the last follow-up(17.82±8.5)mm Hg,96.1% efficient operation,postoperative visual acuity remained unchanged in 39 eyes,visual acuity improved in 7 eyes,6 visual acuity decreased.Preoperative patients with eye pain,eye pain symptoms disappeared or eased,fewer complications,to a lesser degree,mainly uveitis,anterior chamber exudation no eyeball atrophy.Conclusion Long-term follow-up observation,the semiconductor laser transscleral cyclophotocoagulation for refractory glaucoma surgery is a simple,effective and safe method.
