“…Loss of light perception was reported between 11 and 48% of eyes after tube implantation in NVG. [4][5][6][7] Second cause of failure was phitisis bulbi in three eyes (7.9%) in AGV group and four eyes (14.8%) in MSPI group in our study. Phthisis bulbi was secondary to progression of the proliferative retinopathy in all cases.…”

“…Artificial aqueous drainage devices have been advocated for primary surgical treatment of NVG but general success rates varied in different studies. [4][5][6][7][8] In this retrospective study, we evaluated 5-year efficacy and safety of Molteno singleplate implant (MSPI) without pressure ridge and Ahmed glaucoma valve (AGV) in eyes with NVG and examined the factors that influence the outcome.…”

Aims To evaluate the surgical success results of Ahmed glaucoma valve (AGV) and Molteno single-plate implant (MSPI) in cases of neovascular glaucoma (NVG). Methods Between May 1997 and May 2002, 38 of 38 NVG patients that underwent implantation of AGV and 27 eyes of 27 NVG patients that underwent MSPI (a total 65 eyes of 65 patients) included to the study. Results The cumulative probabilities of success were 63.2% at 1 year, 56.2% at 2 years, 43.2% at 3 years, 37.8% at 4 years, and 25.2% at 5 years in AGV group whereas the cumulative probabilities of success were 37.0% at 1 year, 29.6% at 2 years, 29.6% at 3 years, 29.6% at 4 years, and 29.6% at 5 years in MSPI group (P ¼ 0.141). Preoperative visual acuity o2/200 (P ¼ 0.003), diagnosis of diabetes mellitius (P ¼ 0.050), and preoperative IOP Z35 mmHg (P ¼ 0.038) were found to be poor prognostic factors for surgical success. Conclusions Both AGV and single plate MSPI were successful for early and intermediate-term of IOP control but in long term both implants were failed to achieve control of IOP in patients with NVG.

“…A success rate of over 50% with both intraocu lar pressure control and visual acuity is there fore most encouraging and certainly com pares favourably with recent studies using a variety of drainage implants. 7,8,9,14,15,16,17,18,19,20,21 Consideration of visual acuity shows that a successful outcome is significantly less likely in the neovascular glaucomas. This does not relate directly to intraocular pressure control but appears to be due more to the continuing disease process.…”

“…Pre vious studies [1][2][3][4][5][6][7][8][9] have clearly shown the advantages of Krupin-Denver valve implantation in glaucoma surgery as well as the main complications and causes o f failure: hypotony in the early postoperative period, blockage of the in ternal fistula, blockage of the external fistula. Long-term results of Krupin-Denver valve implantation are often con-ditioned by the high mortality of patients [3].…”

The long-term results obtained with the Krupin eye short valve shunt in 28 eyes with neovascular glaucoma were retrospectively analyzed by means of Kaplan-Meier survival curve. The preoperative intraocular pressures (IOPs) ranged from 28 to 62 mm Hg (mean, 36.8 ± 5.8 mm Hg). Success was considered an IOP of less than 22 mm Hg and greater than 5 mm Hg without medication (complete success) or with medication (qualified success) without additional glaucoma filtering surgery or devastating complications. Postoperative success was obtained in 10 out of 28 eyes after a mean follow-up period of 58.4+23.02 months (range, 10-108 months). The 3- and 6-year life table success rates were 66 and 34%, respectively. Early complications were: shallow or flat anterior chamber (15 patients, 53.6%), hypotony (16 patients, 57.1%), hypertony (7 patients, 25%), serous choroidal effusion (7 patients, 25%), fibrinous uveitis (5 patients, 17.9%), blockage of the intracameral portion of the tube by fibrin (5 patients, 17.9%), choroidal hemorrhage (2 patients, 7.1%). Late complications were: external conjunctival bleb failure (12 patients, 42.9%), blockage of the intracameral portion of the tube by fÍbrovascular tissue (5 patients, 17.9%), cataract (2 patients, 7.1%), bullous keratopathy (2 patients, 7.1%), external erosion of the Silastic valve (2 patients, 7.1%), phthisis bulbi (2 patients, 7.1%). Mortality during long-term follow-up was high in our series. The complications of an underlying diabetes mellitus were the most common causes of death (15 out of 22 patients). The high mortality of patients subjected to valve implantation makes it difficult to interpret the results of long-term studies. However, the valve implant is still today an alternative surgical procedure for controlling IOP in eyes with neovascular glaucoma that have visual potential.
