How Evolution is Leading to Gene Therapies for More Retinal Diseases

Dr. John FlanneryAt first blush, gene therapy for retinal diseases seems so simple: Inject a tiny drop of liquid containing good copies of a gene to replace the bad, and you’re home free. Vision is saved, and, in some cases, it’s even restored.

But the reality is: Developing gene therapies that are safe, effective and long-lasting is very challenging in our world of genetically diverse retinal degenerations. Scientists have to design a delivery system that gets the genes to the right types of cells across the entire retina, but without affecting other cells.
