Looking at the Sun without protection can cause permanent retinal damage and blindness, even after just a few seconds of exposure.

These copies are contained inside a harmless virus, which goes through the retinal cells and replaces the defective gene.

The retina, a light-sensitive tissue at the back of the eye, consumes more oxygen than any other tissue in the body and relies on the retinal pigment epithelium cell layer to function properly.

Their results, published in Science Translational Medicine, show the promise that mRNA-based therapies may one day offer patients with PVR and other retinal conditions.

The study, led by Goethe University Frankfurt, sheds light on how specific mutations may lead to the retinal disease retinitis pigmentosa.
