Neovascular glaucoma (NVG) is an aggressive type of glaucoma, which often results in poor visual outcomes. Antivascular endothelial growth factor is frequently used for various conditions in which VEGF release is induced in response to retinal ischemia. Bevacizumab is a humanized anti-VEGF monoclonal IgG1 antibody. The potential of antivascular endothelial growth factor (anti-VEGF) agents to modify the disease course of neovascular glaucoma (NVG) was recognized shortly after their use in the treatment of age-related macular degeneration was reported. These medications were noted to induce rapid regression of the anterior segment neovascularization that characterizes NVG. Several studies as well as extensive clinical experience have demonstrated a rapid regression of anterior segment neovascularization following the injection of anti-VEGF agents. This review aims to summarize current evidences regarding effectiveness of Bevacizumab in management of neovascular glaucoma.

ObjectiveTo determine the effects of the intraocular injection of antivascular endothelial growth factor (anti-VEGF) drugs on the refractive status of infants with retinopathy of prematurity (ROP).DesignSystematic review and meta-analysis of the refractive status of infants with ROP who receive anti-VEGF drugs.Data sourcesThe PubMed, Web of Science and Embase databases and the ClinicalTrials.gov website were searched up to June 2020.Eligibility criteria when selecting studiesWe included randomised controlled trials (RCTs) and observational studies that compared refractive errors between anti-VEGF drug and laser therapies.Data extraction and synthesisData extraction and risk-of-bias assessments were conducted by two independent reviewers. We used a random-effect model to pool outcomes. The outcome measures were the spherical equivalents, axial length (AL), anterior chamber depth (ACD) and lens thickness (LT).ResultsThirteen studies involving 1850 eyes were assessed: 914 in the anti-VEGF drug group, and 936 in the control (laser) group. Children who received anti-VEGF drug treatment had less myopia than those who received laser therapy (mean difference=1.80 D, 95% CI 0.97 to 2.63, p＜0.0001, I2=78%). The AL, ACD and LT did not reach statistical significance difference between the two groups. The current evidence indicates that the refractive safety in children with ROP is better for anti-VEGF drug treatment than for laser therapy.ConclusionsThis meta-analysis indicates that anti-VEGF drug therapy results in less myopia compared with laser therapy. However, there are relatively few published articles on refractive errors in ROP, and so high-quality and powerful RCTs are needed in the future.PROSPERO registration numberCRD42020160673.

Purpose To assess the functional and anatomical outcomes of intravitreal dexamethasone implant Ozurdex® in eyes with diabetic macular edema that did not adequately respond to vascular endothelial growth factor inhibitors. Methods Multicenter, retrospective, and real-life case series study conducted on consecutive diabetic macular edema patients who underwent treatment with one or more dexamethasone implant injections and were followed up for a minimum of 12 months. Subjects were divided into three groups: I—naïve patients, II—previously treated eyes that received three intravitreal antivascular endothelial growth factor inhibitors injections before the study (early switch), and III—previously treated eyes that received >3 intravitreal antivascular endothelial growth factor inhibitors injections before the study (late switch). Primary endpoints were best-corrected visual acuity and central retinal thickness at month 12. Results A total of 129 eyes (21 naïve and 108 previously treated, Group II: 32 and Group III: 76) were included. At month 12, best-corrected visual acuity significantly improved from 0.27 ± 0.23 and 0.31 ± 0.22 at baseline to 0.36 ± 0.25 and 0.37 ± 0.23 at month 12 in naïve and previously treated eyes, respectively, and p = 0.0063 and 0.0060, respectively. Central retinal thickness, in naïve and previously treated eyes, was significantly reduced from 483.0 ± 143.4 and 431.3 ± 115.5 µm, at baseline, to 278.8 ± 72.1 and 269.3 ± 66.2 µm, at month 12, respectively, and p < 0.0001 each, respectively. Best-corrected visual acuity improvement was significantly greater in both absolute and percentage values, p = 0.0393 and 0.0118, respectively, in Group II than in Group III. Conclusion In eyes with insufficient response to antivascular endothelial growth factor inhibitors, switching to dexamethasone at the time to 3-monthly antivascular endothelial growth factor inhibitors injections provided better functional outcomes than those that received >3 antivascular endothelial growth factor inhibitors injections.
