Abstract

Purpose: To investigate intraocular pressure (IOP) control, visual acuity, and complications at 1 year after Ahmed Glaucoma Valve (AGV) implantation. Methods: This was a retrospective, observational study of 35 AGV implanted patients who were followed up to 1-year post-surgery. The AGV implantation was performed at a tertiary healthcare facility in India. The IOP control, visual acuity status, and safety after AGV implantation with a specific modification of surgical technique were evaluated. Results: The study included 35 patients who underwent AGV implantation. The IOP reduced to near-normal levels post-surgery with immediate benefit being seen at Month 1, and the benefit was sustained till Month 12 as measured by the mean IOP. At all-time points post-surgery, patients had stable visual acuity. Post-surgery, the use of medication decreased over time during the study in all patients. There were no new or unexpected complications post-surgery. In most patients, AGV implantation was well-tolerated. Conclusions: AGV implantation with modified surgical technique (tube is not anchored to the sclera and partial thickness scleral flap covers the tube) works very well at intermediate term as regard to IOP control and visual acuity and it is an effective way of treating the patients with refractory glaucoma.
