“…None of our patients developed postoperative corneal decompensation. This is an important finding because previous studies have attested to decreased likelihood of corneal decompensation with ciliary sulcus or PP siting compared to AC siting [36][37][38][39]. Imamoglu et al [37] showed a low risk of corneal decompensation (4.3%) due to posterior AGV implantation in the ciliary sulcus.…”

Background: Pars plana vitrectomy with implantation of an Ahmed glaucoma valve in the vitreous cavity has been reported with a success rate in the management of refractory and neovascular glaucoma. This study aimed to present the outcomes of pars plana Ahmed glaucoma valve (PPAV) surgical implantation in cases with refractory glaucoma. Methods: In this single-center, retrospective, comparative study, 87 consecutive patients diagnosed with refractory glaucoma who underwent PPAV surgical implantation between October 2015 and October 2019 were evaluated. A successful post-op outcome was defined as postoperative intraocular pressure (IOP) less than or equal to 21 mmHg upon examination and a reduction in the number of anti-glaucoma agents used at the latest follow-up. Results: As a final count, 81 eyes of 78 patients with refractory glaucoma were included; 54 (66.66%) of the eyes had neovascular glaucoma. The mean follow-up was 20.65 ± 12.17 months (range: 2?52 months). The mean pre-op IOP was 40.01 ± 1.19 mmHg and reduced significantly to 16.73 ± 0.82 mmHg at the latest follow-up (P < 0.001); thus, a successful IOP outcome was achieved in 88.89% of eyes. The mean number of anti-glaucoma agents decreased significantly from 2.86 ± 0.09 pre-operatively to 1.46 ± 0.11 at the latest follow-up (P < 0.001); while 61 (75.31%) of eyes had a reduction in the number of IOP lowering eye drops, and 14 (17.28%) had no need for IOP lowering eye drops. Conclusions: PPAV surgery is a successful procedure for IOP reduction in patients with refractory glaucoma. Our study demonstrated either elimination or reduction of IOP, lowering eye drops postoperatively. Large scale studies with a comparison group, a longer follow-up, and having various subtypes of glaucoma are required as future research to confirm these outcomes.

“…Another study found that sulcus tube implantation was safe in pseudophakic eyes with a high risk of corneal decompensation, although there was a high incidence of postoperative hyphema 44 . Although these studies present contradictory results, most studies show that hyphema is more common with sulcus tube implantation, compared with anterior chamber or pars plana implantation, likely attributable to the greater vascularization of the ciliary sulcus 45–47 . The hyphema tends to be mild in nature and typically self-resolves without additional intervention 45,47 .…”

[45][46][47] The hyphema tends to be mild in nature and typically self-resolves without additional intervention. 45,47 Pars plana tube insertions have also proven to have similar safety and efficacy profiles compared with the anterior chamber and sulcus insertions and may be even more effective than both alternatives in lowering postoperative medication burden.…”

Glaucoma is the leading cause of irreversible blindness worldwide. Despite the large variety of treatment methods used in glaucoma, most researchers believe that surgery is the most effective way to normalize the level of intraocular pressure and preserve visual functions. Trabeculectomy and glaucoma drainage implantation are the most commonly performed glaucoma surgeries. Although trabeculectomy is the gold standard, at present time there is an uptrend in the use of glaucoma drainage devices. Ahmed glaucoma valve (AGV) is one of the most widely used glaucoma drainage devices in the world. This review of literature presents contemporary results of AGV implantation, possible complications and ways of optimizing that technique.
