AIM: To observe the efficacy and safety of cyclophoto-coagulation through 23G minimally invasive scleral incision in the treatment of refractory glaucoma.

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.
