方法：对23例23眼难治性青光眼患者采用经23G微创巩膜切口睫状体光凝，观察术后眼压、最佳矫正视力、降眼压药物数量、并发症情况。

结果：手术后眼压、最佳矫正视力及降眼压药物数量与术前相比，差异有统计学意义(P<0.05)； 术后并发症少。

结论：经23G微创巩膜切口睫状体光凝术是一种新型且安全有效的治疗难治性青光眼的手术方法。

METHODS: Totally 23 patients(23 eyes)were taken the surgery-the cyclophotocoagulation-through 23G minimally invasive scleral incision. We observed the changes of intraocular pressure(IOP), the best corrected visual acuity(BCVA), the quantity of drugs reducing intraocular pressure and complications in the pre-and post-operation.

RESLUTS: Comparing with preoperative, the postopera-tive IOP, BCVA and the number of IOP-decreased drugs were statistically significant(P<0.05); the complication was fewer.

CONCLUSION: The 23G minimally invasive scleral incision cyclophotocoagulation is a new type of safe and effective surgical method for the treatment of refractory glaucoma.
