The use of the Ahmed glaucoma valve in postpenetrating keratoplasty glaucoma

Background and objective Glaucoma drainage devices have shown promise in intraocular pressure (IOP) control in postpenetrating keratoplasty (post-PK) glaucoma and, at the same time, are minimally invasive to the corneal graft. This study aimed to evaluate the effectiveness of the Ahmed glaucoma val...

description Background and objective Glaucoma drainage devices have shown promise in intraocular pressure (IOP) control in postpenetrating keratoplasty (post-PK) glaucoma and, at the same time, are minimally invasive to the corneal graft. This study aimed to evaluate the effectiveness of the Ahmed glaucoma valve (AGV) in post-PK glaucoma patients. Design The present study was a prospective case series. Patients and methods The study included 20 eyes of 20 patients with refractory post-PK glaucoma who had AGV implanted after variable periods following PK and who were followed up for 6 months postoperatively. Results The mean age of the study population was 40.37±17.02 years. The mean IOP before AGV was 35.71±8.03 (range: 22–58) mmHg. It was reduced postoperatively at the final follow-up to 11.88±2.23 (range: 8–17) mmHg. Complete success was achieved in 35% of the patients and qualified success in 60% with mean IOP-lowering medications of 1.26±1.12 agents. Five cases needed needling with 5-fluorouracil injection. One case experienced early vitreous hemorrhage and failed to be controlled. Graft survival after AGV was 90% at the end of follow-up. Conclusion AGV is an effective treatment for refractory post-PK glaucoma. Although it associated with complications and risk for graft failure, it has to be considered when other treatments fail.
