At the National Eye Institute, researchers have uncovered a molecular conversation between the retina's energy use and the genetic instructions that keep light-sensing cells alive — a discovery that reframes vision loss not merely as a cellular failure, but as a metabolic one. When the eye burns glucose, it leaves chemical signatures on the proteins that govern gene activity, signatures that fade when metabolism falters with age or disease. This finding, published in PLOS Genetics, suggests that the slow dimming of sight in conditions like macular degeneration may be, at its root, a story abou
