Early anti-VEGF treatment of diabetic retinopathy yields no benefit to visual acuity

February 7, 2023

While early treatment of diabetes-related eye disease slowed progression to severe disease, it did not improve visual acuity compared with treating more severe disease once it developed, according to a clinical study from the DRCR Retina Network.
