A US veteran, Aaron James, 46, made medical history as the first recipient of an eye transplant from another person. James miraculously survived a 2021 accident involving a 7,200-volt electric shock, which caused extensive injuries to his left arm, nose, lips, front teeth, left cheek, chin, and necessitated the removal of his eye.
In May, an unprecedented 21-hour surgery involving 140 medics in New York City successfully performed the world’s first eye and partial face transplant on Aaron James. Previously, eye transplants were deemed unfeasible due to the intricate nerve and blood vessel connections to the brain. However, doctors now believe there’s potential for James, a father, to regain vision in the transplanted eye. While experts recognize this as a significant advancement, they caution that it’s too soon to determine if this marks a breakthrough in curing blindness, a condition affecting over 2.2 billion people worldwide, as per the World Health Organization.
In the UK, about 340,000 individuals are registered as blind or partially sighted. Blindness can arise from injuries like chemical burns, accidents, or physical altercations. Infections can also cause blindness, though they’re less common in the UK. Globally, trachoma is a major preventable cause, while in the UK, age-related macular degeneration, cataracts, glaucoma, and strokes impacting vision-related brain areas are leading causes of vision loss.
Some severe forms of blindness can be treated with medication or surgery. Eye drops, for instance, can alleviate glaucoma by reducing eye pressure. Surgical interventions can correct structural eye issues, such as cataract surgery that replaces a cloudy lens with an artificial one. However, not all blindness is treatable. For these cases, support is provided to maximize any residual vision or aid in adapting to blindness. Innovations in technology are also aiding those with sight loss, like advanced glasses developed by Oxford University, which use video cameras to enhance object visibility for people with partial vision.
Dr. Eduardo Rodriguez, who led a groundbreaking eye transplant surgery at NYU Langone, views it as a major step towards potentially restoring vision. The patient, Aaron James, currently can’t see with the new eye, but the team is hopeful for future improvements. Experts, including Dr. Peter Hampson, caution that it’s too early to consider this a cure for blindness due to the surgery’s complexity, especially the challenge of connecting the optic nerve’s million nerve fibers. The potential for this surgery to restore sight fully may not be understood for years, emphasizing the importance of regular eye exams for early detection and treatment of vision issues.
In a groundbreaking 21-hour procedure, a 140-person team performed a face and eye transplant on Aaron James. The surgery involved removing parts of James’s face and preparing the donor’s face and eye in separate rooms. The critical challenge was connecting the donor eye to James’s optic nerve, using adult stem cells from the donor’s bone marrow to encourage nerve regeneration and possibly restore vision. James recovered in intensive care for 17 days before transitioning to outpatient rehabilitation. Read the full story:
