The Mean

Purpose. Intravitreal antivascular endothelial growth factor (anti-VEGF) therapy has been widely used for the treatment of neovascularization (NV) secondary to age-related macular degeneration (AMD). This study aimed to compare the efficacy among different subtypes of neovascular age-related macular degeneration (nAMD). Methods. PubMed, Embase, and the Cochrane Library were searched for eligible studies. We performed meta-analysis using Review Manager 5.3 and Stata/SE 12.0. Results. A total of 24 studies met our inclusion criteria and were included in the systematic review. At 3 months, the mean logarithm of the minimum angle of resolution (logMAR) improvements were −0.09, −0.18, and −0.23 for type 1, 2, and 3, respectively, while the mean macular thickness (MT) changes were −104.83, −130.76, and −196.29 μm. At 12 months, the mean changes in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters were 6.38, 8.12, and 9.37, while the MT decrease was 126.51, 126.52, and 139.85 μm, respectively. However, statistically significant difference was only found between type 1 and 3 in vision improvement, both in the short term (p=0.0002) and long term (p=0.01). Conclusions. The reactivity to VEGF inhibitors varied among different subtypes of nAMD. The efficacy of intravitreal anti-VEGF therapy in type 3 nAMD was statistically better than type 1 when considering vision improvement at 3 and 12 months. Thus, the lesion subtype is a predictor for the treatment outcome which can help guide prognosis.

Time Point

AIM: To evaluate the efficacy and safety of intravitreal corticoid as an adjunctive therapy to anti-vascular endothelial growth factor (VEGF) treatment of neovascular age-related macular degeneration (nvAMD). METHODS: Four databases including PubMed, Embase, Cochrane Library, and the clinicaltrials.gov were comprehensively searched for studies comparing intravitreal corticoid plus anti-VEGF (IVC/IVA) vs anti-VEGF monotherapy (IVA) in patients with nvAMD. GRADE profiler was used to assess the quality of outcomes. Best-corrected visual acuity (BCVA), central macular thickness (CMT) and adverse events including the occurrence of severe elevation of intraocular pressure (IOP) and the progress of cataract were extracted from the eligible studies. Review Manager (RevMan) 5.3 was used to analyze the data. RESULTS: There was no statistic difference of mean change in BCVA at 6 and 12mo between IVC/IVA and IVA group [95% confidence interval (CI): -2.28 to 4.24, P=0.55; 95%CI: -3.01 to 8.70, P=0.34]. No statistic difference was found in the change of CMT between two groups at 6mo time point (95%CI: -17.98 to 16.42, P=0.93) while the CMT reduction in IVC/IVA group was significantly more obvious than IVA group at 12mo time point [mean difference (MD)=-44.08, 95%CI: -80.52 to -7.63, P=0.02]. The risk of occurrence of severe elevation of IOP in the IVC/IVA group was higher than that in the IVA group (95%CI: 1.92 to 9.48; P=0.0004). Cataract progression risk was calculated no statistic difference between two groups (95%CI: 0.74 to 4.66; P=0.18). CONCLUSION: No visual or anatomical benefits are observed in IVC/IVA group at 6mo. At 12mo, the CMT of the IVC/IVA group is significantly lower than that of the IVA group. Risk of severe elevation of IOP is significantly higher when treated by IVC/IVA.

Abstract Background Age-related macular degeneration (AMD) causes irreversible vision loss, and targeted anti-vascular endothelial growth factor (VEGF) therapy is now the most common and effective treatment. The aim of this meta-analysis is to discuss whether genetic polymorphism of ARMS2 A69S could confer susceptibility to advanced AMD with the response to anti-VEGF treatment.Methods We performed a meta-analysis of relevant published studies selected through electronic databases. A total of 21 preferred studies regarding the association between ARMS2 gene and anti-VEGF treatment response in advanced AMD were generally included in the meta-analysis.Results The pooled results demonstrated that the carriage of G allele for ARMS2 A69S presented a better clinical prognosis for advanced AMD treated with anti-VEGF drugs (OR=1.38, 95% CI=1.13-1.69, P=0.002). Additionally, in the subgroup analysis based on ethnicity, ARMS2 polymorphisms were more likely to be a positive responder for East Asian patients (OR=1.67, 95% CI=1.29-2.16, P<0.001).Conclusion This meta-analysis through a series of rigorous methodology data demonstrated a significant association between ARMS2 A69S polymorphism and the anti-VEGF treatment response in advanced AMD, especially among East Asian population. Numerous well-designed, randomized, multicenter clinical trials with large sample size are required to validate the association.
