“…Previously, Ahmed glaucoma valve (AGV) implantation was reserved for glaucoma patients poorly controlled after one or more filtration procedures, however recent evidence has recently encouraged its use as a primary surgery in refractory glaucoma such as secondary to neovascular glaucoma (NVG), pars plana vitrectomy (PPV), penetrating keratoplasty, and uveitis 9. Unfortunately, the AGV has limitations of a small surface area and hypertensive phase 10-13 and its reported success rate varies greatly depending on the follow-up period and types of glaucoma 10, 14-16. Importantly, effect of AGV on treatment of specific NVG has received little attention from the scientific world so far.…”

To evaluate the efficacy of Ahmed glaucoma valve (AGV) implantation in treating neovascular glaucoma (NVG) and analyze the factors influencing the surgical success rate, a retrospective investigation of 59 NVG patients (66 eyes) who underwent AGV implantation was conducted at Jiangsu Province Hospital, China, from January 2014 to June 2018. Intraocular pressure (IOP), visual acuity, surgical success rates, medications, and complications were monitored at post-operative 1 day, 1 week, 1, 3, 6 and 12 months. Surgical success criteria were defined as 6 mm Hg < IOP < 21 mmHg with or without additional medications. Results showed average IOP was statistically significant between pre-operative visit and each follow-up visit (all P<0.05). At 12 months, the success rate was 66.7%. Multiple stepwise regression analysis suggested that age, panretinal photocoagulation (PRP), complications and hyphema were significant factors influencing the surgical success rate (all P<0.05). Thus, we conclude that AGV implantation is effective and safe for treatment of NVG. Surgical success is dependent on age, PRP, complications, and hyphema.

“…Its one year safety and efficacy has been published. [45] A rare complication like tube cut has been reported before with the Baerveldt implant which was managed with the help of a Tube Extender (New World Medical, Inc, Rancho Cucamonga, CA). [6] The use of an angiocatheter segment or a 22-G intravenous catheter for retracted tube has also been reported.…”

We report a novel simplified method for managing inadvertent tube cut in a patient undergoing the Aurolab aqueous drainage implant (AADI) surgery for refractory neovascular glaucoma. Tube cut occurred while applying the polyglactin ligature suture used to avoid early postoperative hypotony. The short end of the cut tube was removed and the long end reinserted into the base plate of AADI. The surgery was then completed as usual. Following the surgery, the intraocular pressure reduced to 20 mmHg which stabilized and was maintained at 10 mmHg till the last follow-up at 12 months without any glaucoma medication.

“…The literature has a number of studies comparing outcomes between the valved and non-valved GDDs. 5–7 The AADI implant has recently been shown to have greater intraocular pressure (IOP) reduction at 1 year compared to the Ahmed valve with a favorable safety profile, 5 and this has been confirmed in a prospective randomized trial of 18 adult patients. 8 However, there are a lack of data comparing outcomes of the AADI with the BGI drainage device.…”

Purpose: The Aurolab® aqueous drainage implant is a low-cost alternative to the Baerveldt glaucoma implant. The aim of this study was to test the hypothesis that the two implants are comparable in terms of surgical success and safety. Methods: We conducted a retrospective case-control study of Aurolab aqueous drainage implant done at our institution from May 2015 and May 2017. Twenty-five consecutive patients who received an Aurolab aqueous drainage implant were matched by age and diagnosis to patients who received a Baerveldt glaucoma implant. Data were collected pre-operative and post-operative visits, including visual acuity and intraocular pressure, number of medications, and complications. Surgical success was defined as intraocular pressure between 5 and 21 mmHg with a minimum 20% reduction from baseline, without loss of light perception or the need for further glaucoma surgery. Cox regression analysis was used to predict factors associated with surgical success. Results: The median (interquartile range, IQR) intraocular pressure at 1 year was 16.0 (8.0) mmHg for the Baerveldt glaucoma implant and 13.0 (8.0) mmHg for the Aurolab aqueous drainage implant, p = 0.38. Success (mean ± SE) at 1 year for the intraocular pressure >21-mmHg failure criterion was 65% ± 15% for the Baerveldt glaucoma implant and 79% ± 11% for the Aurolab aqueous drainage implant (p = 0.80). The frequency of complications listed was similar for the two groups (Fisher’s exact p = 0.71). In the Cox regression, the type of implant was not found to be associated with surgical success. Conclusions: Our preliminary results suggest that the Aurolab aqueous drainage implant is comparable to the Baerveldt glaucoma implant. Further long-term data in a larger population are needed to confirm these findings.
