巩膜单通道睫状突眼内光凝治疗无晶状体青光眼

Effect of laser photocoagulation of ciliary processes by single channel of sclera in aphakic glaucoma

目的探讨直视下行巩膜单一通道睫状突眼内激光光凝治疗无晶状体眼青光眼的疗效。方法对28例（28眼）无晶状体眼性青光眼作11点位扁平部巩膜穿刺口，3点位透明角膜缘做眼内灌注，术中将810nm、0．5w二极管激光导管经平坦部切口插入，结合巩膜外顶压，根据术前眼压情况选择显微镜直视下进行90°～200°范围光凝。术后观察视力、眼压、眼内组织反应等，平均随访时间8个月。结果术后眼压逐渐下降，与术前眼压（42．34±7．55）术后最后1次随访眼压（18．34±1．92）mmHg比较，差异有统计学意义（F=63．71，P=0．011〈0．05）。结论经巩膜单通道行眼内光凝睫状突治疗无晶状体眼青光眼能有效地降低眼压，减少了并发症。

Objective To explore the therapeutic effect of laser photocoagulation of ciliary processes by single channel of sclera in aphakic glaucoma. Methods 28 patients （28 eyes） with aphakic glaucoma, sclera incision was done at the 11：00 position, intraocular perfusion at the 3：00 position of the limbus, a probe of semi-conductor diode laser（810 nm,0.5W）was inserted through the sclera incision, combined with pressing the sclera, ciliary processes were photocoagulated in 90 -200 degree range by the intraocular pres- sure（IOP） before surgery. Visual acuity, IOP and ocular tissue reaction were observed after surgery. The mean follow-up period was 8 months. Results The intraocular prssure gradually declined, The IOP at the last visit was （ 18.34 ＋ 1.92） mmHg, which was significantly lower than that before the surgery （P 〈 0.05 ）. Conclusion Laser coagulation of ciliary processes by single channel of sclera in aphakic glaucoma could reduce the IOP, and decrease the complications.
