AIM: To investigate the outcome and safety of Ahmed glaucoma valve implantation treatment in uncontrolled primary congenital glaucoma(PCG).

METHODS:Twenty-two eyes in 22 children with uncontrolled PCG were reviewed retrospectively and underwent Ahmed glaucoma valve implantation treatment from January 2011 to December 2014. Main checking index included intraocular pressure(IOP)before and after operation, corneal diameter and complications.

RESULTS: Preoperative mean age was 3.74±2.24y, and 2.59±1.78y apart from the last operation. Postoperative average IOP was 35.22±6.36mmHg. Average corneal diameter was 12.79±0.75mm. Mitomycin C(0.3-0.5mg/mL)was used in all operations for 3-5min. Glaucoma valves were implanted in the temporal or nose above the equator sclera. Postoperative IOP was 11.4±4.45mmHg at 1wk, and 16.73±7.23mmHg after 12mo. As IOP<21mmHg for success criteria, IOP of 16 eyes(73%)were controlled after 12mo. Preoperative 6 cases had shallow anterior chamber, recovered spontaneously. No serious complication was recorded, such as rejection of glaucoma valve, endoophthalmitis and corneal decompensation.

CONCLUSION: Ahmed glaucoma valve implantation in uncontrolled PCG is a safe and viable treatment.
