OBJECTIVE To describe short term outcomes of Ahmed Glaucoma Valve [AGV] implantation in East African patients. METHODS In this multi-center retrospective case series we reviewed eyes of Black African patients with refractory glaucoma, treated consecutively with Ahmed Glaucoma Valve implantation, in two centers in Kenya between January 2006 and October 2007. RESULTS About 25 cases including 18 [72%] pediatric eyes and seven [28%] adult eyes were identified. Results have been presented with a median follow-up of two months with inter-quartile range [IQR] of one to 12 months. intraocular pressure [IOP] was reduced from a mean of 36.4 mmHg preoperatively to 16.7 mmHg and glaucoma medications were lowered from a mean of 1.32 before surgery to 0.2 after surgery. The success rate during short term follow-up was 79%. The mean visual acuity dropped slightly from 6/18 pre-operatively to 6/24. There was only one major complication of an extruded, infected valve in a child. CONCLUSIONS The Ahmed Valve Implant is safe and effective in lowering IOP for the short term in pediatric and adult East African patients with refractory glaucoma. Further studies with more patients and longer term follow-up are needed in this population.
