Background: Refractory glaucoma still represents a challenge for ophthalmologists to manage intraocular pressure. The present study aimed to evaluate long term efficacy and safety of a second Ahmed valve implantation after the failure of a first implant in patients with refractory glaucoma and elevated intraocular pressure (IOP). Methods: Retrospective, multicenter non-comparative case series. Twenty-eight patients were retrospectively recruited between January 2011 and December 2017. Demographic data, glaucoma type, visual acuity, intraocular pressure, medical therapy, and complications were registered. Three criteria of success were established: Type 1 surgical success: IOP ≤ 15 mmHg and a reduction of IOP ≥ 40% from baseline; Type 2 surgical success: IOP ≤ 18 mmHg and a reduction of IOP ≥ 30% from baseline; and Type 3 surgical success: IOP ≤ 21 mmHg and a reduction of IOP ≥ 20% from baseline. Surgical failure has been established as IOP less than 5 mmHg or over 21 mmHg and less than a 20% reduction of IOP from baseline despite medications in two consecutive visits, light perception loss referable to glaucoma, and the necessity for further glaucoma surgery. Failure was observed in six (21%) patients. (3) Results: Mean IOP and mean glaucoma medication number significantly reduced from baseline after the second implantation, and the surgical success rate at 72 months ranged from 10% to 78% based on the different criteria of success. Failure was observed in six (21%) patients. Conclusions: This study confirmed the safety and efficacy of a second Ahmed valve implantation in patients with refractory glaucoma and elevated IOP at baseline.

The purpose is to evaluate the effectiveness and safety of Ahmed valve implantation in children with refractory postuveitic glaucoma (PUG).Material and methods. Ahmed valve was implanted to 10 children aged 7 to 17 years (10 eyes) with open-angle or mixed PUG uncompensated even by a maximum antihypertensive mode. Previously, all patients had undergone an average of 2.1 ± 0.9 surgeries aimed at normalizing the intraocular pressure (IOP) (predominantly, sinus trabeculectomy). 6 eyes were pseudophakic, 2 phakic, 2 aphakic. Ahmed valves were implanted according to the generally accepted technique. At the time of surgery IOP was 30.50 ± 4.35 mm Hg on average. The follow-up postsurgical period ranged from 3.9 to 23.6 months (averagely, 14.1 ± 6.5).Results. A stable hypotensive effect of the intervention was achieved in 90 % of cases, of which 3 patients had no hypotensives while 6 patients received hypotensive drugs even though their quantity was significantly smaller than before surgery (1.7 ± 1.49, p=0.028). At the end of the follow-up the average IOP was 18.1 ± 5.34 mm Hg, (significantly lower than before surgery, p = 0.008). During surgery, 1 patient experienced bleeding from the vessels of the anterior chamber angle after paracentesis, which was stopped by tamponade with sterile air. In other cases, the surgery as well as the immediate and distant postoperative period showed no complications.Conclusion. Ahmed valve implantation is an effective and safe method of the surgical treatment of refractory PUG in children and can be recommended in cases when previous antiglaucomatous operations proved ineffective, including patients with pseudophakia and aphakia.

Purpose: To assess the efficacy and safety of a standardized micropulse transscleral diode laser cyclophotocoagulation procedure in refractory glaucoma. Methods: Retrospective, interventional study in a series of 37 consecutive patients with refractory glaucoma, cyclodestructive procedure-naive, who underwent micropulse transscleral diode laser cyclophotocoagulation from December 2016 to October 2017. A successful laser treatment was defined as (1) intraocular pressure between 6 and 18 mm Hg; (2) 20% of baseline intraocular pressure reduction; (3) no additional glaucoma medications; (4) no decrease in vision due to complications or change in intraocular pressure; and (5) no need for additional glaucoma surgery except micropulse transscleral diode laser cyclophotocoagulation retreatment. Results: Mean age was 60.2 years. Mean follow-up was 9.7 ± 3.9 months. The mean preoperative intraocular pressure (28.7 mm Hg) significantly decreased to 21.0 mm Hg at 1 month, 18.5 mm Hg at 3 months, 18.4 mm Hg at 6 months, and 18.5 mm Hg at 12 months ( p < 0.01 at all time points). The mean number of preoperative glaucoma medications (4.7) decreased to 4.0 at 1 month ( p = 0.14), 4.5 at 3 months ( p < 0.05), 3.9 at 6 months ( p < 0.05), and 3.6 at 12 months ( p < 0.05). At 1 year, the success rate was 35% with a mean intraocular pressure lowering of 36%. One patient had hypotony and a loss of best-corrected visual acuity. Mild transient postoperative inflammation was observed in 8% of the cases. Conclusion: Using a standardized procedure, micropulse transscleral diode laser cyclophotocoagulation allows a mild intraocular pressure decrease with a low rate of complications and thus achieves a relatively good profit risk benefit, mostly for moderately hypertensive refractory glaucoma.
