To assess the safety and efficacy of the non-valved glaucoma implant (GI) with plate size 350 mm2 in patients with refractory glaucoma for a long time.

GI are widely used in the treatment of refractory glaucoma where İOP  compensation cannot be achieved with traditional trabeculectomy. Refractory glaucoma can be caused by iris neovascularization, trauma, uveitis, congenital pathologies of the eye, excessive scarring of the conjunctiva after trabeculectomy.

The study included 137 patients (145 eyes) who underwent implantation of AADİ GI. All patients were followed for 60 months. Visual acuity (VA), changes of intraocular pressure (IOP), use of glaucoma medications, incidence of complications and postsurgical interventions were examined.

At the final 60 months examination the mean preoperative visual acuity increased from 0.12±0.01(0-0.8) to 0.20±0.03(0-0.8) (p<0.05), the IOP and glaucoma medications decreased from a mean of preoperative value of 40±1.0(14-66) mmHg and 2.9±0.05(2-4) to mean 15.3±0.9(5-38) mmHg

(p<0.01) and 1.47±0.17(0-3) (p<0.01) respectively. Complications of the early and late postoperative period were detected in 68 eyes (47%). Complete success was achieved in 42.8% (IOP ≥6 and ≤21 mmHg without drops), qualified in 42.8% (IOP ≥6 and ≤21 mmHg with drops) and failure (IOP < 6 and >21 mmHg) in 14.3% of cases. Additional procedures were performed on 34 (23.5%) eyes in the operating room and 18 (12.4%) eyes in the examination room.

The use of non-valved GI when standard glaucoma surgery is unsuccessful or unacceptable is a long-term effective treatment option in terms of lowering IOP. After surgery, you should be prepared for complications associated with hypotony and the tube of the GI.
