Clinical evaluation of Ahmed glaucoma valve implantation for uncontrolled primary congenital glaucoma

Abstract

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