AIM: To study the surgical method and curative effect of non-penetrating trabeculectomy combined with 90 degrees trabeculotomy(NPTST).

METHODS:A total of 15 patients(30 eyes)with congenital infant glaucoma from January 2010 to January 2012 underwent NPTST. The change of intraocular pressure(IOP), corneal diameter and incidence rate of postoperative complications were observed respectively.

RESULTS:Compared to preoperation, the IOP in the group was lower at week 1, month 1, 3, 6 and 12, corneal diameter keep original size or a slight decrease, less complications occurred.

CONCLUSION: NPTST is a safe and effective surgical treatment of congenital infant glaucoma with high successful rate and low incidence rate of postoperative complications.
