目的:研究二极管激光经巩膜睫状体光凝术治疗难治性青光眼的有效性及激光治疗参数。方法:对我院收治的50例50眼晚期难治性青光眼患者行二极管激光经巩膜睫状体光凝术,记录每位患者所用能量,击射范围,光凝点数,爆破点数,观察患者治疗前后的眼压、眼部症状,视力、裂隙灯观察眼前节的改变和并发症等。结果:术后平均眼压(18.50±2.50)mmHg,术后眼压较术前明显下降(P<0.01)。术后46眼疼痛明显减轻,术前术后眼压差值与击射能量的相关性不高;眼压下降值与击射范围、击射点数呈正相关性,眼压下降值与爆破点数显著相关,呈正相关性。结论:二极管激光经巩膜睫状体光凝术治疗难治性青光眼是一种安全有效的方法,激光治疗参数需根据术前眼压、不同类型青光眼进行设计。

AIM:To investigate the outcome and treatment parameter of transscleral diode laser cyclophotocoagula-tion in refractory glaucoma. ·METHODS:Fifty patients 50 eyes of refractory glaucoma were treated with the transscleral diode laser cyclo-photocoagulation,the power,area,points of photocoa-gulation,points of blast were recorded,intraocutar pressure(IOP),symptom,visual acuity,the representa-tion of anterior segment before and after treatment and the complication were observed. ·RESULTS:The average of IOP was 18.50±2.50mmHg after treatment,obviously decreased after treatment (P<0.01). The pain decreased in 46 eyes,the decreasing amount of IOP was not obviously correlated with power,but had relativity with area and points of cyclo-photocoagulation,and had obvious positive relativity with points of blast. ·CONCLUSION:It is a safe and effective method to treat the refractory glaucoma with transscleral diode laser cyclophotocoagulation; and it is important to design the treatment parameter acording to the IOP before treatment and different type glaucoma.
