Intravitreal injections with aflibercept (Eylea) don’t improve the visual acuity of people with nonproliferative diabetic retinopathy (NPDR), researchers say. The treatments do reduce the risk for center-involved diabetic macular edema and proliferative diabetic retinopathy, however, said Adam R. Glassman, MS, principal investigator of the DRCR Retina Network Coordinating Center, Tampa, Florida. “Some clinicians may decide

How is the retina formed? And how do neurons differentiate to become individual components of the visual system? By focusing on the early stages of this complex process, researchers at the University of Geneva (UNIGE), Switzerland, in collaboration with the École Polytechnique Fédérale de Lausanne (EPFL), have identified the genetic programs governing the birth of

How are the images cast on the retina reassembled in the brain? Researchers in Munich and Tuebingen find that processing of visual stimuli occurs at the earliest waystation on the way to the visual cortex—but not all inputs are treated equally. In humans, the visual system collects up to 80 percent of all the sensory

A study involving scientists from the University of Alicante and the United States notes that the accumulation of a protein known as alpha-synuclein in the retina is a key Parkinson’s biomarker that could help detect the degree of severity of the disease. The work has been published this month in Movement Disorders, a journal in
