Okamoto M, et al. - Researchers ascertained the impacts of an intravitreal injection of ranibizumab (IVR) on the choroidal structure and blood flow in eyes with diabetic macular edema (DME). As per the findings, the central retinal thickness could be reduced and BCVA improved by a single IVR in eyes with DME in both the no-PRP and PRP-treated group. The choroidal vasculature and blood flow were significantly affected by IVR. Researchers noted that the central retinal thickness and the choroidal blood flow in eyes without PRP were significantly correlated.
