The utility of intravitreal bevacizumab injection in a patient with neovascular glaucoma following central retinal vein occlusion is explored. Bevacizumab (1 mg in 0.04 mL) was used after failed intraocular pressure (IOP) control with transscleral cyclophotocoagulation and panretinal photocoagulation. IOP improved within 2 days and the patient experienced marked improvement in comfort. Bevacizumab may be an effective medication for the treatment of neovascular glaucoma.

Herein three cases of angle closure secondary to neovascularization (elevated intraocular pressure in two of the cases) treated with the anti-vascular endothelial growth factor (VEGF) monoclonal antibody bevacizumab (Avastin) are reported. In all three cases there was rapid resolution of neovascularization and control of intraocular pressure. One patient with corneal anaesthesia from diabetes developed infectious keratitis, potentially as a consequence of inhibition of VEGF wound healing and neurotrophic functions. Avastin appears to have a promising role in the treatment of neovascular glaucoma but is not without potential local and systemic side-effects.

Neovascular glaucoma is a secondary glaucoma with grave prognosis which follows ischemic retinal disorders in the majority of cases. Mediators that induce new vessel formation such as the vascular endothelial growth factor-A seem to play a key role in the pathophysiology of this condition. Herein, we report 2 cases with neovascular glaucoma secondary to ischemic central retinal vein occlusion who received treatment with intravitreal bevacizumab (Avastin) a nonselective antibody against vascular endothelial growth factor-A. Both patients demonstrated dramatic short-term response in terms of intraocular pressure reduction and regression of neovascularization.

The rubeosis of the iris is a serious complication especially in diabetic retinopathy and retinal veins occlusion. Cytokines, especially the vascular growing factor (VEGF), are responsible for the forming of new vessels. The treatment that inhibits the effect of the VEGF presents new possibilities in the neovascular diseases treatment. Bevacizumab (Avastin) is an anti-VEGF antibody that blocks all forms of VEGF-A. In three eyes with proliferative diabetic retinopathy and neovascularization of the iris and the anterior chamber angle, the dose of 1.25 mg of Avastin was applied intravitrealy. Just one week after the application of the drug, the decrease of the leakage on the iris, and the total disappearance of the neovascularization in three weeks were visible on the fluorescein angiogram. The recurrence of the neovascularization was found in one eye after three months and the treatment had to be repeated. Nine months after the second application, the disease is stabilized without the neovascularization. The intraocular pressure was elevated in two eyes before the application of Avastin, and was refractive to the treatment. After the disappearance of the neovascularization, the intraocular pressure was normalized and it was possible to terminate the antiglaucomatous therapy. The bevacizumab intravitreal treatment of the neovascularization of the iris and the anterior chamber angle was proved to be efficient, the neovascularization disappeared and the intraocular pressure was normalized. There were no side effects after the bevacizumab applications in any of our patients.

The aim of this study is to report short-term effect of the treatment of "wet" ARMD (age-related macular degeneration) with intravitreal bevacizumab (Avastin). Prospective study included 36 patients (36 eyes) with "wet' form of ARMD. All patients were over 60 year old (22 female, 14 male). Changes of macula included minimally classic CNV (choroidal neovascularisation) (24), occult subfoveal CNV (10) and first stage of cicatrial CNV (2). Bevacizumab 1.25 mg was administered intravitreally through pars plana using a 27-gauge needle. Patients had no previous eye treatment. Ophthalmic exam before and after the treatment included: Snellen VA (visual acuity) and examination including measurement of IOP (intraocular pressure), FA (fluorescein angiography) and interview with patients. After 4-6 weeks 28 (78%) patients had significant improvement of VA. Median VA improved from 0.083 to 0.200 (p<0.01). Eight patients (22%) had no significant improvement in VA but three of them reported to see more light. FA showed complete resolution of macular edema in 6 patients (17%), partially resolved in 23 patients (64%) and no change in 7 patients (19%). No systemic side-effect was found. Short-term results suggest that intravitreally administered bevacizumab is well tolerated treatment for ARMD with very high number of patients showing improvement in VA.

Bevacizumab is increasingly discussed as adjuvant treatment for rubeosis and for all stages of neovascular glaucoma. In incipient rubeosis bevacizumab has a preventive effect and arrests the progression of disease. In the case of increasing involvement of the anterior chamber angle, bevacizumab should be integrated into stage-adapted treatment to achieve successful control of intraocular pressure. The treatment of the causative ischemic stimulus is necessary in every stage of disease. One further indication for bevacizumab is the postoperative inhibition of angiogenesis after glaucoma surgery. Possible routes of administration are subconjunctival application during trabeculectomy, postoperative needling, or intravitreal injection during a filtrating operation. This review summarizes results of current studies about bevacizumab for rubeosis, neovascular glaucoma, or filtrating surgery and adds future perspectives for possible therapeutic schemes.

This retrospective case series reports sustained elevation of intraocular pressure (IOP) after single or repeated intravitreal injections of bevacizumab (Avastin; Genentech, San Francisco, CA) for wet age-related macular degeneration (AMD). All six cases experienced significant and sustained elevation in IOP after single or repeated intravitreal injections of bevacizumab. Initiation or advancement of IOP-lowering therapy was required in all cases. The results support the need for further studies investigating the incidence of this potential side effect and the need for close long-term surveillance of IOP after injection of bevacizumab, particularly in patients with glaucoma or suspected glaucoma. Future in vitro and in vivo studies are needed to better understand the reasons for this observed phenomenon.

We report a case of ocular ischemic syndrome accompanied by neovascular glaucoma that was successfully treated with Bevacizumab. A 70-year-old male patient diagnosed with neovascular glaucoma of the left eye 3-4 years prior complained of continuous left eye pain and declining visual acuity despite receiving the latest treatment methods. At the time of admission the patient had no light perception in the left eye and his intraocular pressure was 30 mmHg. Anterior segment and fundus examinations revealed neovascularization of the iris and stenosis of the retinal vessel. Hypofluorescence of the choroid and retinal vessels was observed on fluorescence fundus angiography. Left internal carotid artery stenosis was observed on a brain MRI. Despite being treated with eye solution and oral medication, intraocular pressure was not controlled. After 7 days, we performed an intravitreal Bevacizumab 1.25 mg/0.05mL injection. One day after the intravitreal Bevacizumab injection, the neovascularization had nearly regressed and intraocular pressure was 30 mmHg. Intravitreal Bevacizumab injection produced regression of neovascularization and proved effective for treatment of neovascular glaucoma in this case of ocular ischemic syndrome.

We report the use of bevacizumab (Avastin) as an additional strategy in angle closure glaucoma based on the case of 47 years old male qualified to cataract removal as anti-glaucoma procedure, in whom we observed iris and lens neovascularization. As a first step we administered 1.25 mg of bevacizumab into the anterior chamber. Iris as well as lens neovasularization completely disappeared after 48 hours later. Finally after lens removal we achieved deeper anterior chamber, reduction and stabilization of intraocular pressure without necessity of administration hipotensive agents, and improvement of visual acuity.

We evaluate the effect of intravitreal injections of Bevacizumab (IVB) alone or combined with triamcinolone (IVT) in the first injection for treatment of refractory diabetic macular oedema (DME). Sixty eyes of sixty patients with refractory DME were included. Half of them received injections of IVB (1.25 mg/0.05 ml) or combined IVB and IVT (1.25 mg/0.05 ml and 2 mg/0.05 ml respectively). The primary outcome measure was change in central macular thickness (CMT). Secondary outcome measures were change in best-corrected logMAR visual acuity (BCVA) and incidence of potential adverse events. Central macular thickness was reduced significantly in both the IVB and IVB/IVT groups. At week 24, CMT change compared to the baseline was -93.7 microm (95% CI, -172.2 to -19.26) in the IVB group and -93.1 microm (95% CI, -154.4 to -29.7) in the IVB/IVT group. There was not a significant difference between the IVB and the IVB/IVT groups. Improvement of BCVA was initiated at weeks 6 and 12 in the IVB/IVT and IVB groups respectively. Anterior chamber reaction was noticed in six (20%) and six (20%) eyes respectively in the IVB and IVB/IVT groups the day after injection, and it resolved with no sequel. Elevation of intraocular pressure (IOP) occurred in two eyes (6%) in the IVB/IVT group. Intravitreal injections of Bevacizumab had a beneficial effect on refractory DME in terms of CMT reduction and BCVA improvement. Addition of triamcinolone in the injection seemed to induce earlier visual improvement; however, it did not show any significant additive effect later during follow-up.
