Picture MUST credit: Joshua Prezant/University of Miami. The possibility of eye transplants to et blind people see again has moved a step closer with a new invention. Eyes require a constant supply of oxygenated blood, which is difficult to supply after an eye has been removed from a donor's body. If that flow of oxygen ceases for even a short time, the eye's retina will permanently cease to function. But now scientists have developed an eye-transplant device known as the eye-ECMO. An ECMO stands for "extracorporeal membrane oxygenation,” a system used to oxygenate patients' blood during heart and lung transplants. The new device for eyes is being developed by US scientists from the University of Miami, along with US institutions the Bascom Palmer Eye Institute and the Miller School of Medicine. The idea is that when an eye is removed from a brain-dead donor's body before their clinical death occurs it gets placed in the eye-ECMO. This continuously pumps warmed, oxygenated blood mixed with a "unique solution" in and out of the eye. As long as that liquid circulates, the eye remains alive and functional. The setup is portable and self-contained enabling the donor eye to be moved from one operating room to another, or even between different hospitals. Picture supplied by JLPPA
