Role of intravitreal bevacizumab in neovascular glaucoma.

We report on the effect of intravitreal bevacizumab (IVB) for the treatment of neovascular glaucoma (NVG). A retrospective chart review of 6 consecutive cases of NVG was performed. The follow-up period was 3-19 months (average, 9.7 months). All patients received 1.25 mg (0.05 cc) of IVB followed by panretinal photocoagulation (PRP) approximately 1 week later. In all cases, there was a complete regression of iris and anterior chamber angle neovascularization. However, 2 eyes showed a recurrence of neovascularization; in 1 case, it recurred after 3 months, and in the second, after 5 months. These patients received another IVB injection followed by additional PRP, which resulted in the resolution of the recurrent neovascularization. Glaucoma was controlled with topical eye drops alone in patients who had iris and angle neovascularization without peripheral anterior synechiae (PAS). However, patients with PAS at the time of presentation needed subsequent glaucoma surgery. Our study suggests that IVB may be a valuable addition in the treatment of NVG by hastening the resolution of anterior segment neovascularization, improving the results of glaucoma surgeries, and appears to give long-term control when used in combination with PRP.     

Bevacizumab联合Ex-press引流管治疗新生血管性青光眼

目的:探讨玻璃体腔注射贝伐单抗(bevacizumab)联合Ex-press青光眼引流管植入术治疗新生血管性青光眼的疗效和安全性。方法:对18例19眼新生血管性青光眼患者,先行玻璃体腔注射bevacizumab,待虹膜新生血管消退或萎缩后,再行Ex-press青光眼引流管(P-200)植入术,其中6例6眼联合超声乳化白内障吸除术。根据患者屈光介质情况术前或术后尽量行全视网膜光凝。Ex-press植入术后随访12mo,观察视力、眼压和手术并发症情况。结果:玻璃体腔注药后2~7d,16眼新生血管全部消退。术后平均眼压:1mo:13.05±2.46mmHg,3mo:13.80±1.88mmHg,6mo:14.30±1.38mmHg;12mo:14.60±1.43mmHg,术后1,3,6,12mo眼压与术前相比均有显著性差异(P<0.05),且术后1,3,6,12mo眼压相比均无显著性差异(P>0.05)。19眼术后视力有提高者4眼,无明显改变15眼,无视力下降眼,完全成功11眼(58%),部分成功5眼(26%),总手术成功率84%(16/19)。术后并发症:有2例术后早期短暂浅前房,散瞳1wk后前房恢复正常,1例前房少量积血,无排斥反应和严重并发症。结论:玻璃体腔注射bevacizumab可使新生血管青光眼虹膜新生血管迅速消退或萎缩,为下一步青光眼手术创造良好的条件。Ex-press青光眼引流管植入术是新的滤过性手术,该手术创伤小,不用切除虹膜,减少了术中、术后出血的风险,联合bevacizumab是治疗新生血管性青光眼的安全而有效的术式。     

新生血管性青光眼治疗策略的初步探讨

目的 建立以完成全视网膜光凝为目标,抗VEGF治疗和抗青光眼手术为核心治疗手段的新生血管性青光眼(neovascular glaucoma,NVG)的综合治疗方法,探讨NVG的治疗策略.方法 设计NVG治疗流程,纳入NVG患者9例10只眼进行综合治疗,治疗方法包括药物降眼压、眼内抗VEGF治疗、单独或联合白内障及玻璃体切割手术的抗青光眼手术以及在此基础上完成全视网膜光凝治疗.随诊6～18(平均9.7)个月,观察患者眼压、视功能及虹膜及房角新生血管状况.结果 本组患者治疗前眼压(42.30±10.25)mmHg,治疗后末次随诊眼压(17.30±4.86)mmHg,统计学分析差异具有统计学意义(P＜0.001).治疗后7只眼视力明显提高.末次随诊时8只眼虹膜及房角新生血管消退.结论 以完成全视网膜光凝为目标,抗VEGF治疗和抗青光眼手术为手段的NVG综合治疗方法能有效控制患者眼压并最大限度保护患者的视功能.

Abstract：

Objective To establish the efficacy and safety of comprehensive therapy for neovascular glaucoma (NVG) by which the main goal is to complete pan-retinal photocoagulation (PRP) and the core treatment is anti-VEGF injection/anti-glaucoma operation,and to discuss the treatment strategies.Methods To design a medical treatment process for NVG.Ten eyes of 9 patients treated with comprehensive therapy including medications for decreasing intraocular pressure (IOP),combination cataract remove/vitrectomy/anti-glaucoma operation or anti-glaucoma operation alone and compete PRP after all the basis treatment.To observe IOP,visual function and anterior chamber angle neovascularization for 6-18 months follow-up (average,9.7months).Results The mean IOP was 42.30 mmHg (± 10.25) before treatment,and the mean IOP was 17.30mmHg (± 4.86) after treatment.The difference had statistic significance (P＜0.001).Visual acuity of 7 eyes was improved significantly after treatment.Iris and anterior chamber angle neovasculization of 8 eyes were regressed completely at the last follow-up.Conclusions IOP is well controlled and visual function is preserved maximum with comprehensive therapy for NVG by completing PRP and anti-VEGF/anti-glaucoma operation.     

Combination intravitreal bevacizumab/panretinal photocoagulation versus panretinal photocoagulation alone in the treatment of neovascular glaucoma

PURPOSE: To evaluate same-day combination intravitreal bevacizumab/panretinal photocoagulation (PRP) for the treatment of neovascular glaucoma (NVG) compared with PRP alone. METHODS: This was an institutional review board-approved, retrospective, consecutive case-control study of patients receiving same-day combination bevacizumab/PRP or PRP alone as treatment of NVG from September 2004 through June 2007. Visual acuity, intraocular pressure (IOP), presence of anterior segment neovascularization, and required glaucoma interventional procedures were recorded. RESULTS: A total of 23 patients were identified, 11 in the bevacizumab/PRP group and 12 in the PRP alone group. The bevacizumab/PRP group had a significant reduction in IOP compared with the PRP alone group (-11 vs. 0 mmHg, respectively; P = 0.03). There was a significantly higher frequency and rate of neovascular regression in the combination therapy group than in the PRP only group (11 vs 2 eyes [P < 0.001] and 12 vs 127 days [P < 0.0001], respectively). Average follow-up was 143 days for the bevacizumab/PRP group and 118 days for the PRP alone group. CONCLUSIONS: Combination treatment resulted in more rapid decrease in IOP. In addition, the combination group had increased frequency and rapidity of regression of neovascularization. This study provides a foundation for further research and suggests consideration for a possible new paradigm for the treatment of NVG.     

Intravitreal bevacizumab (Avastin) in the treatment of neovascular glaucoma

PURPOSE: To describe a case series of neovascular glaucoma (NVG) caused by central retinal vein occlusion (CRVO) that was treated with intravitreal bevacizumab (IVB; Avastin). DESIGN: Retrospective interventional case series. METHODS: Six consecutive patients with NVG and a refractory, symptomatic elevation of intraocular pressure (IOP) and pronounced anterior segment congestion received IVB (1.25 mg/0.05 ml). Diode laser cyclophotocoagulation was carried out only if pressure was controlled insufficiently by topical medication. Follow-up examinations occurred at four to 16 weeks. RESULTS: IVB resulted in a marked regression of anterior segment neovascularization and relief of symptoms within 48 hours. IOP decreased substantially in three eyes; in the other three eyes, adjuvant cyclophotocoagulation was necessary. No side effects were observed. Panretinal photocoagulation (PRP) was performed as soon as feasible, five to 12 weeks after IVB treatment. CONCLUSION: IVB leads to a rapid regression of iris and angle neovascularization and should be investigated more thoroughly as an adjunct in the management of NVG.     

Intravitreal bevacizumab and aqueous shunting surgery for neovascular glaucoma: safety and efficacy

Objective: To study the safety and efficacy of intravitreal injection of bevacizumab followed by aqueous shunting tube surgery for the management of neovascular glaucoma (NVG).Study Design: A prospective, non-randomized study with a historical control group.Participants: Twenty eyes of 20 patients with intractable NVG were treated with intravitreal injection of bevacizumab followed by aqueous shunting surgery (IVB group). A historical group of 10 NVG eyes treated with panretinal photocoagulation followed by aqueous shunting surgery without bevacizumab injection was used for comparison (PRP group).Methods: Injection of bevacizumab (1.25 mg/0.05 mL) was performed under topical anesthesia. An Ahmed valve was implanted in all cases after 1-2 weeks. In the IVB group, 10 eyes received postoperative panretinal photocoagulation (subgroup IA), and 10 eyes were followed without further photocoagulation (subgroup IB). Minimum follow-up was I year or when failure was diagnosed.Results: Mean preoperative intraocular pressure (IOP) was 46.5 mm Hg in the IVB group and 49.2 mm Hg in the PRP group (p = 0.5). After bevacizumab injection, iris neovessels regressed markedly. The final IOP after aqueous shunting tube surgery was 18.8 mm Hg in the IVB group and 15.9 mm Hg in the PRP group (p = 0.2). Postsurgical complications were comparable between the groups. The success rate was 85% and 70% in the 2 groups, respectively. Two eyes were considered failures, and 3 required repeated bevacizumab injections in subgroup IB as compared with I in subgroup IA.Conclusion: Intravitreal bevacizumab is a useful preparatory step to safely and effectively implant an aqueous shunting tube in NVG. Panretinal photocoagulation after bevacizumab injection promotes the success rate of aqueous shunt surgery by permanent ablation of the ischemic retina.     

Intracameral anti-VEGF injection for advanced neovascular glaucoma after vitrectomy with silicone oil tamponade

AIM: To evaluate the effect of intracameral injection of conbercept for the treatment of advanced neovascular glaucoma(NVG) after vitrectomy with silicone oil tamponade.METHODS: Conbercept 0.5 mg/0.05 m L was injected into the anterior chamber of 5 eyes, which had developed advanced NVG after vitrectomy with silicone oil tamponade. Then, trabeculectomy with mitomycin C and pan-retinal photocoagulation(PRP) or extra-PRP were conducted within 2 d. The follow-up time was 6 mo. Best-corrected visual acuity(BCVA), intraocular pressure(IOP), neovascularization of iris(NVI) were recorded before and after treatment.RESULTS: Within 2 d after injection, IOP control, and NVI regression were optimal for trabeculectomy. Hyphema occurred in one eye in the process of injection. But none of them present hyphema after trabeculectomy. At the end of follow-up time, all eyes had improved BCVA, well-controlled IOP, and completely regressed NVI. CONCLUSION: Intracameral injection of conbercept is safe and effective in the treatment of patients with advanced NVG after vitrectomy with silicone oil tamponade. Within 2 d after injection is the optimal time window for trabeculectomy, which can maximally reduce the risk of perioperative hyphema.     

Intravitreal Bevacizumab for the Treatment of Neovascular Glaucoma Associated With Central Retinal Artery Occlusion

We report three cases of neovascular glaucoma secondary to central retinal artery occlusion (CRAO) which were effectively managed with intravitreal bevacizumab (IVB) followed by panretinal photocoagulation (PRP). Neovascular glaucoma without peripheral anterior synechiae developed between one and five weeks following CRAO onset. All patients received 0.75 mg (0.03 ml) IVB. In all patients, complete regression of the iris and anterior chamber angle neovascularization was confirmed within one week. PRP was applied two weeks after the injection. The follow-up period was four to seven months (average, five months). Intraocular pressure was controlled in all patients using topical antiglaucoma medications alone. However, one patient experienced a recurrence of neovascularization three months after the initial combination treatment. This patient received another IVB injection and additional PRP, and the recurrent neovascularization resolved. There were no local or systemic adverse events in any patients. Therefore, intravitreal bevacizumab may be an effective adjunct in the treatment of neovascular glaucoma associated with CRAO.

Efficacy and safety of intravitreal ranibizumab with panretinal photocoagulation followed by trabeculectomy compared with Ahmed glaucoma valve implantation in neovascular glaucoma

AIM: To evaluate the efficacy and safety of intravitreal ranibizumab (IVR) with panretinal photocoagulation (PRP) followed by trabeculectomy compared with Ahmed glaucoma valve (AGV) implantation in neovascular glaucoma (NVG). METHODS: This was a retrospective comparative study. We reviewed the cases of a total of 45 eyes from 45 NVG patients among which 23 eyes underwent AGV implantation and the other 22 underwent trabeculectomy. The causes of neovascular glaucoma included: diabetic retinopathy (25 eyes), and retinal vein occlusion (20 eyes). All patients received preoperative IVR combined with postoperative PRP. The mean best-corrected visual acuities (BCVA) were converted to the logarithms of the minimum angle of resolution (logMAR) for the statisitical analyses. Intraocular pressure (IOP), the logMAR BCVA and surgical complications were evaluated before and after surgery. The follow-up period was 12mo. RESULTS: A total of 39 cases showed complete regression of iris neovascularization at 7d after injection, and 6 cases showed a small amount of residual iris neovascularization. The success rates were 81.8% and 82.6% at 12mo after trabeculectomy and AGV implantation, respectively. In the trabeculectomy group, the logMAR BCVA improved at the last follow-up in 14 eyes, remained stable in 6 eyes and decreased in 2 eyes. In 4 cases, slight hyphemas developed after trabeculectomy. A shallow anterior chamber developed in 2 cases and 2 vitreous hemorrhages. In the AGV group, the logMAR BCVA improved in 14 eyes, remained stable in 5 eyes and decreased in 4 eyes. Slight hyphemas developed in 3 cases, and a shallow anterior chamber in 3 cases. The mean postoperative IOP was significantly lower in both groups after surgery (F=545.468, P<0.05), and the mean postoperative logMAR BCVA was also significantly improved (F=10.964, P<0.05) with no significant difference between two groups. CONCLUSION: It is safe and effective to treat NVG with this combined procedure, and we found similar results after IVR+AGV implantation+PRP and IVR+trabeculectomy+PRP in eyes with NVG.     

Current approaches in neovascular glaucoma

Neovascular glaucoma (NVG) has long been recognized as a very difficult case to manage for its very poor prognosis of visual function. NVG is also remarked as an 'end stage' of ocular diseases. Conventional treatments with extremely uncontrolled cases are retinal cryotherapy or enucleation. Currently, management of this medical condition is directed toward a new era with great advancement in diagnosis and treatment. Glaucoma drainage implant surgery brings a time window of normal range of intraocular pressure (IOP) for physicians to process underlying disease of NVG. Regression of iris neovascularization by employing panretinal photocoagulation (PRP) or intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) antibodies create a chance to undertaken antiglaucomatous surgery. Adjunctive anti-VEGF treatment promotes the surgical success rate for NVG. Current approaches in NVG are able to provide patients with an individualized management using a sound treatment strategy according to etiology, stage of disease, visual potential and other factors.

Combined diode laser cyclophotocoagulation and intravitreal bevacizumab (Avastin) in neovascular glaucoma

Background: Intravitreal injection of bevacizumab (Avastin) in eyes with neovascular glaucoma (NVG) has recently been shown to induce rapid regression of anterior segment neovascularization and has promise as adjunct treatment to diode laser cyclophotocoagulation (CPC) to control intraocular pressure (IOP). This study presents the outcome of concomitant treatment with CPC and intravitreal bevacizumab in painful poor visual potential eyes in a case series of consecutively diagnosed NVG. Methods: Twelve patients (14 eyes) were treated with CPC and concurrent intravitreal bevacizumab 0.05 mL (1.25 mg) and study end‐points were IOP lowering, regression of anterior segment neovascularization and resolution of pain. Results: The mean preoperative IOP was 42.1 ± 11.4 and was lowered to 16.6 ± 7.1 mmHg at 1‐month postoperatively. Anterior segment neovascularization regressed dramatically within 1 week of intravitreal bevacizumab in 12 eyes. Thirteen eyes reported persistent relief of ocular pain at 6 months following treatment. Conclusions: Combined intravitreal bevacizumab and CPC treatment for NVG provides rapid control of anterior segment neovascularization and may lead to improved symptomatic relief and IOP control.

Comparison of healing patterns of different side-cut angulations after FS-LASIK

AIM: To investigate and evaluate healing patterns around flaps made with different side-cut angulations after femtosecond laser in situ keratomileusis(FS-LASIK).METHODS: Thirty-four patients(68 eyes) received a 90° side-cut(n=34) or a 120° side-cut flaps(n=34) made with a femtosecond laser. One day, 1 wk, 1 and 3 mo postoperatively, side-cut scar was evaluated under slit-lamp photography according to a new grading system(Grade 0=transparent scar, 1=faint healing opacity, and 2=evident healing opacity). In vivo corneal confocal microscopy and anterior segment optical coherence tomography(AS-OCT) were used to observe wound-healing patterns around flap margin in the two groups. Sirius Scheimpflug Analyzer was also used to analyze higher order aberrations 3 mo after surgery.RESULTS: There were no significant differences in flap wound-healing patterns at each follow up between the two groups(P>0.05). Three months after surgery, the flap edge scar classified as Grade 0 had excellent apposition and rapid nerve regeneration. At 3 mm and 5 mm pupil diameters, there were significant differences in trefoil aberrations between the two groups(P<0.05), but no statistically significant differences were found in total higher order aberrations(HOAs), spherical aberrations or coma in any of the pupil size conditions(P>0.05).CONCLUSION: Flap edge scars classified as Grade 0 have excellent apposition and rapid nerve regeneration, and 120° side-cut angle flaps induce less trefoil aberrations after FS-LASIK.
