A Review of the Ahmed Glaucoma Valve Implant and Comparison with Other Surgical Operations

The Ahmed glaucoma valve (AGV) is a popular glaucoma drainage implant used for the control of intraocular pressure in patients with glaucoma. While in the past AGV implantation was reserved for glaucoma patients poorly controlled after one or more filtration procedures, mounting evidence has recently encouraged its use as a primary surgery in selected cases. AGV has been demonstrated to be safe and effective in reducing intraocular pressure in patients with primary or secondary refractory glaucoma. Compared to other glaucoma surgeries, AGV implantation has shown favorable efficacy and safety. The aim of this article is to review the results of studies directly comparing AGV with other surgical procedures in patients with glaucoma.

“…Patients with any of these risk factors may benefit from alternative nonincisional therapies such as transscleral diode cyclophotocoagulation, which does not have an associated infection risk and has shown to have similar outcomes at 2 years compared to AGV in patients with NVG and preoperative visual acuity of hand motions or worse. 16 Surgery selection and perioperative treatment should be based on patient characteristics influencing visual potential, wound healing, and known bacterial colonization. …”

Complication of an Ahmed glaucoma valve implant: tube exposure with methicillin-resistant Staphylococcus aureus infection

SummaryNeovascular glaucoma is commonly treated surgically with implantation of glaucoma drainage devices. We report the case of a 57-year-old man who underwent an uneventful Ahmed glaucoma valve (AGV) placement for radiation-induced neovascular glaucoma but later developed early postoperative infection with tube exposure. The infection was identified 3 weeks postoperatively and antibiotic treatment was immediately initiated. However, the conjunctival melt progressed, and the AGV had to be removed. Culture of the device revealed methicillin-resistant Staphylococcus aureus (MRSA). There is a potential increased risk of postoperative infection and tube exposure following glaucoma valve implantation in patients with previous radiation therapy. To our knowledge, this is the second case in the literature of MRSA causing early postoperative infection following drainage device placement that required explantation.

“…TSCPC with and without the use of anti-VEGF has been shown to be effective in lowering IOP and relieving pain in advanced cases of NVG 99,100 . When compared to AGV implantation in a randomized controlled trial, no significant difference was found in the success rate at 24 months between the diode cyclophotocoagulation (61.18 %) and AGV valve implantation (59.26 %) in NVG treatment 101 .…”

Certain types of glaucomas do not respond to conventional trabeculectomy; they are named refractory glaucomas. They are notorious and often recurrent. Examples include: childhood, neovascular, uveitic, traumatic, glaucomas with wide conjunctival scars, post-vitrectomy, post-keratoprosthesis, post-keratoplasty, ciliary block, recurrent and glaucoma in aphakic and pseudophakic eyes. Some of those glaucomas require specific medical management like uveitic glaucoma. However, surgical intervention is ultimately needed in most of cases. Different surgical strategies include: antimetabolites-assisted trabeculectomy, drainage implants, cyclodestructive surgeries and other approaches. This review article will discuss the current management strategies for refractory glaucomas and the application of those treatment modalities to the specific glaucoma types.

A Comparative Study Between Diode Laser Cyclophotocoagulation and the Ahmed Glaucoma Valve Implant in Neovascular Glaucoma

Abstract: There was no significant difference in the success rate between the DCPC and AGV implantation in neovascular glaucoma treatment. However, DCPC is less time consuming and easier method for lowering IOP in patients with neovascular glaucoma.
