NCT02131350

Brief Summary

The purpose of this study is to evaluate the mean gain in best corrected visual acuity and the number of intravitreal ranibizumab (IVR) injections under the combination treatment of IVR, focal/grid laser and panretinal photocoagulation. Our hypothesis is that suitable photocoagulation decreases the number of IVR injections.
