Meta-analysis of best corrected visual acuity after treatment for myopic choroidal neovascularisation

To compare the best corrected visual acuity (BCVA) between Verteporfin with photodynamic therapy (PDT) and intravitreal anti-vascular endothelial growth factor (anti-VEGF) in patients with myopic choroidal neovascularization (CNV).

Published literature from Medline, Premedline, Embase and the Cochrane Library from inception until November 2013 were retrieved. All studies evaluating the BCVA between Verteporfin with PDT and intravitreal anti-VEGF for myopic CNV were included. The results were pooled using mean difference (MD), a corresponding 95% confidence interval (CI).

Finally, five studies enrolled 349 eyes were included in the meta-analysis. We inferred that the BCVA of myopic CNV after the treatment of anti-VEGF was significantly better compared with Verteporfin with PDT (MD=0.25, 95%CI:0.17-0.33, Z=5.97, P<0.00001).

This meta-analysis suggests that intravitreal anti-VEGF could have a better BCVA after treatment than Verteporfin with PDT for myopic CNV.
