A team of researchers at the University of Utah successfully revived the human retina outside the body for up to 10 hours after death, fundamentally reshaping our understanding of clinical death and neural cell degeneration. The technique involved connecting the eye to a closed perfusion system that supplied blood and oxygen within 30 minutes of death, allowing the preservation of the eye's vital structure and the generation of visual signals. This achievement paves the way for complete eye transplants and enables more precise and realistic studies of blindness mechanisms and the testing of neuroprotective drugs.
