Combination Treatment of Intravitreal Ranibizumab, Focal/Grid Laser and Panretinal Photocoagulation in Patients With Diabetic Macula Edema

September 5, 2018 updated by: Takao Hirano, Shinshu University
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.
