“…They suggested that AV implantation may be more effective than trabeculectomy in uveitic glaucoma. 10,11 Even though the cumulative probability of success at 1 year (94.4%) was similar to that of De Mata et al's study; 11 the cumulative probability of success at 2 years (60%) was relatively low in our study.…”

“…A significant amount of IOP decrease has been reported in all studies evaluating AV implant's success. [9][10][11]19,22,23 In large and heterogeneous series of glaucoma treated with AV implantation, a mean decrease of 16.8 mmHg in IOP and a decrease of 1.6 in the number of antiglaucoma medications were achieved. A success rate of 87% at 1 year and 75% at 2 years after surgery were reported.…”

“…1 The condition becomes more challenging when the elevated intraocular pressure (IOP) is unresponsive to medical treatment. To improve the surgical outcome of these cases, alternative approaches such as trabeculectomy with antiproliferative agents, 2-7 aqueous drainage devices with or without trabeculectomy, [8][9][10][11][12][13][14] trabeculodialysis, 15,16 and transscleral diode laser cyclophotocoagulation 17 have been proposed. Most studies suggest using antiproliferative agents in terms of long-term IOP control in those patients.…”

Ahmed valve implantation in glaucoma secondary to chronic uveitis PÇ Ö zdal, RNG Vianna and J Deschê nes AbstractPurpose To evaluate the efficacy of Ahmed valve (AV) implantation in patients with uveitic glaucoma. Methods In total, 18 patients (19 eyes) with glaucoma secondary to chronic uveitis, who underwent AV implantation were retrospectively reviewed. Visual acuity, intraocular pressure (IOP), and glaucoma medications at the most recent examination prior to surgery, were compared with those of last postoperative examination. The surgical success was defined as IOP less than 21 mmHg and greater than 4 mmHg without loss of light perception and visually devastating complications at the last postoperative examination. Decrease in the number of glaucoma medications was also a criterion for surgical success. Results The mean follow-up period was 2679.7 months. The mean preoperative and postoperative IOPs were 33.379.7 (range, 20-57) mmHg and 17.3710.8 (range, 6-40) mmHg respectively (Po0.0001). The mean number of antiglaucoma medications was 3.570.8 (range, 2-5) preoperatively and 1.471.3 (range, 0-4) postoperatively (Po0.0001). Valve occlusion (five eyes, 26.3%) was the most commonly observed complication. Surgical success was achieved in 13 eyes (68.4%). The cumulative probability of success was 94.4% at 1 year and 60% at 2 years. Five eyes (26.3%) with IOP greater than 21 mmHg and one (5.3%) with corneal decompensation requiring penetrating keratoplasty were considered as failures. Conclusions The implantation of AV is an effective surgical procedure for the management of uveitic glaucoma. The inflammatory background might contribute to the occurrence of valve occlusion, which is the most common complication. Prevention of this complication is an essential factor for improving the surgical outcome.

“…Indeed, a valve mechanism has been introduced in an attempt to prevent complications sometimes encountered with non-valved GDIs, such as hypotony, shallow anterior chamber, choroidal effusion and choroidal detachment [14]. Several studies have shown that AGV is safe and effective in reducing IOP in patients with primary [15][16][17], secondary [18][19][20][21][22][23][24] and refractory glaucoma [25][26][27]. However, the hypotensive efficacy of AGV in comparison with other anti-glaucoma interventions has not been completely elucidated.…”

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.

Purpose To evaluate the efficacy of the Ahmed Glaucoma Valve implant in refractory glaucomas in Indian eyes. Materials and methods A retrospective review was conducted on the charts of 122 eyes of 122 patients with refractory glaucoma treated with Ahmed Glaucoma Valve implant placement at Guru Nanak Eye Centre, New Delhi between January 1996 and December 1999. The main outcome measure was success at the last follow-up. Success was defined as an intraocular pressure (IOP) of 22 mmHg or less and 5 mmHg or more and at least a 30% reduction in IOP without visually devastating complications or additional glaucoma surgery. Results The mean postoperative IOP (17.2973.79 mmHg) was significantly (Po0.001) lower than the mean preoperative IOP (31.4777.86 mmHg) at last follow up (mean 12.5178.37 months; range 3-24 months). The cumulative probability of success by Kaplan -Meier analysis was 85.95% at 12 months and 82.83% at 24 months. The mean number of postoperative antiglaucoma medications (0.7570.80) was also significantly lower (Po0.001) than the mean preoperative number of antiglaucoma medications (2.83 þ 0.72). The most common complication was corneal-tube contact, which occurred in five (4.10%) eyes. Retinal detachment occurred postoperatively in one eye with the clinical diagnosis of neovascular glaucoma secondary to Eale's disease. Two patients had tube extrusion requiring repositioning and reinforcement with scleral patch graft. Conclusions Ahmed Glaucoma Valve implantation is an effective and relatively safe therapy for the treatment of refractory glaucoma in Indians.
