Purpose. To evaluate the outcomes of Ahmed glaucoma valve (AGV) implantation in vitrectomized eyes. Materials and Methods. The medical records of 13 eyes that developed glaucoma due to emulsified silicon oil or neovascularization following pars plana vitrectomy and underwent AGV implantation were retrospectively reviewed. The main outcome measures were intraocular pressure (IOP), best-corrected visual acuity (BCVA), number of antiglaucoma medications, and postoperative complications. Surgical success was defined as last IOP ≤21 mmHg or ≥6 mmHg and without loss of light perception. Results. The mean follow-up duration was 11.7 ± 5.5 (range, 6–23) months. The mean IOP before the AGV implantation was 37.9 ± 6.7 mmHg with an average of 3.5 ± 1.2 drugs. At the final visit, the mean IOP was 15.9 ± 4.6 mmHg (p=0.001) and the mean number of glaucoma medications decreased to 2.3 ± 1.3 (p=0.021). At the last visit, 11 eyes (84.4%) had stable or improved VA and one eye (7.7%) had a final VA of no light perception. Surgical success was achieved in 11 of the 13 eyes (84.4%). Postoperative complications were bleb encapsulation (69.2%), early hypotony (38.5%), hyphema (23.1%), decompression retinopathy (23.1%), choroidal detachment (15.4%), intraocular hemorrhage (7.7%), and late endophthalmitis (7.7%). One eye (7.7%) was enucleated because of late endophthalmitis. Conclusions. Despite complications necessitating medical and surgical interventions, vitrectomized eyes were effectively managed with AGV implantation.

This study aimed to evaluate the 3-year long-term outcomes of primary Baerveldt glaucoma implant (BGI) surgery for neovascular glaucoma (NVG). We retrospectively evaluated 27 consecutive patients with NVG between November 2013 and November 2017. All the patients were treated with panretinal photocoagulation and pars plana vitrectomy before BGI surgery without anti-vascular endothelial growth factor treatment. The surgical success of the BGI was defined as an IOP of <22 mmHg and <5 mmHg with or without antiglaucoma medication. The outcomes were assessed on the basis of intraocular pressure (IOP), visual acuity, postoperative complications, and cumulative success rate. Except for 2 mortality cases, 25 eyes (92.6%) were followed up for 3 years. The mean IOPs (mmHg)/numbers of glaucoma medications ± standard error of the mean before and 12 and 36 months after BGI surgery were 41.6/4.6 ± 1.9/0.2, 14.8/2.2 ± 0.8/0.4 and 16.9/2.6 ± 1.1/0.3, respectively. In all of the follow-up time points, the postoperative mean IOP and number of glaucoma medications were statistically significantly lower than the preoperative values (analysis of variance, P < 0.001). At 3 years after surgery, the rates of visual acuity improvement (logMAR ≤ −0.3), invariance (−0.3 < logMAR < 0.3), and worsening (logMAR ≥ 0.3) were 56.0% (14/25 eyes), 24.0% (6/25 eyes), and 20.0% (5/25 eyes), respectively. The most common postoperative complications were hyphema (4 eyes, 14.8%) and vitreous hemorrhage (5 eyes, 18.5%), and serious complications such as expulsive hemorrhage, endophthalmitis, and tube/plate exposure did not occur. The cumulative probabilities of surgical success after the operation were 100% at 1 year, 85.2% at 2 years, and 77.4% at 3 years. In conclusion, combined non-valved pars plana tube placement in conjunction with vitrectomy was successful at lowering IOP with relatively low complication rates.

Ahmed Glaucoma Valve Implantation

Specific postoperative complications, such as tube exposure and conjunctival erosion, have occurred despite the favorable surgical outcomes of tube shunt surgeries for refractory glaucoma. The new autologous scleral pocket technique is performed by inserting the tube into the vitreous cavity without using a donor scleral patch. The purpose of this study was to evaluate the surgical results of Ahmed glaucoma valve (AGV) implantation using this technique for neovascular glaucoma (NVG), which is one of the representative refractory types of glaucoma. This observational retrospective case series included 15 consecutive eyes of 15 patients with NVG who had undergone AGV implantation at Kobe University between January 2018 and December 2019. The mean preoperative intraocular pressure (IOP) was 37.2 ± 13.8 mmHg and the glaucoma drug score was 4.2 ± 2.2. The mean IOP and glaucoma drug score at 1 year postoperatively decreased to 15.0 ± 4.6 mmHg and 1.3 ± 2.0, respectively (p < 0.001). No significant change in the corneal endothelial cell density following surgery was observed (p = 0.09); however, one patient required an additional trabeculectomy at 7 months postoperatively. No cases of tube exposure or conjunctival erosion were observed at 1 year postoperatively. These results indicated the effectiveness and safety of this technique in patients with NVG.

Abstract Purpose: To evaluate the clinical outcomes of pseudophakic/aphakic eyes with uncontrolled glaucoma that underwent Ahmed glaucoma valve implantation with the tube placement in the ciliary sulcus.Methods: Medical records of the patients who underwent Ahmed glaucoma valve implantation through the ciliary sulcus, between December 2017 and June 2019, were reviewed retrospectively. Patients’ age, gender, glaucoma diagnosis, visual acuity, intraocular pressure levels and complications were recorded. Results: Forty-seven eyes of 43 patients with glaucoma were enrolled. The mean age was 54.5 ± 19.9 years (range, 7 - 88 years) at the time of surgery and the mean postoperative follow-up period was 7.9 ± 3.4 months (range, 3 -16 months). The mean preoperative intraocular pressure level was 35.2 ±6.8 mmHg (range, 25-55 mmHg) and it was found as 15.6 ± 5.4 mmHg (range, 9-33 mmHg) at last follow-up visit. Decrease in intraocular pressure level was statistically significant (P < 0.001). At last follow-up visit success was achieved in 41 eyes (87.2 %). Hyphema was the most common postoperative complication and developed in 11 eyes (23.4%) and resolved spontaneously in all of them within one month.Conclusion: In pseudophakic or aphakic eyes with uncontrolled glaucoma, placement of Ahmed glaucoma valve tube in the ciliary sulcus is a safe and effective procedure. Ciliary sulcus can be considered as a potential space during tube shunt surgery in eyes with high risk of tube-corneal touch or corneal decompensation.

Purpose: To evaluate the results of the trabeculectomy without antimitotic in children aged 5 to 15 years and identify the factors of success of this technique. Method: we have conducted a retrospective study based on records of children of 5 to 15 years, operated from January 2011 to December 2013 for glaucoma excepted congenital glaucoma. The trabeculectomy was performed without antimitotic and the follow up was done during 6 months. Nineteen children (35 eyes) were included over 23 children (43 eyes) operated. Surgical success was defined for intra ocular (IOP) ≤ 20mmhg (target pressure) pressure associated with a pressure reduction over 30% with or without topical medication and major postoperative complications. Results: On the 19 included Sham children (35 eyes) the mean age was 9.05 years [5;15], 11 were of boys and 8 girls and the sex ratio was 0.73. The mean cup/disc of the papillary excavation was 0.54 [0.2; 0.8]. The mean preoperative IOP was 20.08 mm Hg [11;30]. Postoperative complications was seen in 17% (6 eyes) with 11.4% (4 eyes) of hypothalamy. The mean post operative IOP at 6 months was 12.86 mm Hg [10; 23]. The success rate was 62.86% (22 eyes). IOP control was the only factor influencing the success of surgery (p = 0. 0055). Conclusion: The trabeculectomy without antimitotic allowed a substantial reduction in IOP. The control of IOP determine the success of the surgery at 6 months. The spreading of the technique with the use of an antimitotic will optimize our results.

Aim: to assess visual outcome and complications associated with SFIOL implantation in traumatic lens subluxation/ dislocation cases. Methods: This is a retrospective study of 45 patients who were managed for traumatic dislocation/subluxation of clear or cataractous lenses from June 2019 to July 2020 in a Krishna hospital, Karad, Satara. All cases underwent anterior vitrectomy/3 port pars plana vitrectomy + removal of lens and ab externo 2 point scleral fixation with rigid or foldable sfiol. In posteriorly dislocated/subluxated lens, vitrectomy was done and the lens was removed using pick forceps and retrieved by hand shake technique. In anteriorly dislocated cataractous lens, the lens was removed through the tunnel incision. Results: Majority of the patients were between 55-65 years of age with male pre-ponderance (73.3%).Out of 45 cases, 21 cases (46.6%) were traumatic dislocated lens and 24 cases (53.3%) were traumatic subluxated lens. The mean preoperative BCVA was 0.13 ± 0.24 logMAR, which improved 0.39 ± 0.366 logMAR postoperatively (P <0.0001 ).Preoperatively BCVA in logMAR in 39 cases (86.6%) was 0.3 or better, 6 cases (13.3%) was 0.3 to 1.0 . Postoperatively BCVA in logMAR in 21 cases (46.67%) was 0.3 or better, 24 cases (53.3%) was 0.3 to 1. P-value is 0.00057 which is significant. Early postoperative complications noted were raised intraocular pressure in 12 cases (26.6%), corneal edema in 9 cases (20%), vitreous hemorrhage in 8 cases (17.7%)  and hypotony in 3 cases (6.67%).Late postoperative complications were persistent elevation of intraocular pressure in 10 cases (22.2%), cystoid macular edema in 3 cases (6.67%), epiretinal membrane in 3 cases (6.67%). Conclusion: In every horrendous case, long haul follow-up is needed to distinguish confusions and start treatment at the most punctual.
