Summary
When one eye is lost, darkness reigns. And those who treat trauma to the eye and disease are, in a sense, groping in the dark themselves. They have little to offer the girl who stumbled while trick-or-treating on Halloween night, cracking his skull and severing the optic nerve, or 60, which sees only light and shadows, because glaucoma destroyed cells in the same conduit. Vijay Gorantla, a plastic and reconstructive surgeon at the University of Pittsburgh Medical Center, with colleagues there and in nine other centers want to turn the eye transplants science fiction into reality. They have their work cut out for them. The most formidable challenge is coaxing nerves to regenerate and connect the eye from donor to recipient, and there are a host of other obstacles, too. But those who hold the purse strings are ready to play, and researchers hope the first models in pigs and rats serve as a guide.
