| Surgeons have implanted a mini telescopic prosthetic in the eye of a patient with end-stage age-related macular degeneration, a leading cause of blindness
A tiny telescope implant, is the only medical option available that restores a portion of vision lost to the disease. UC Davis Health System’s Eye Center, in collaboration with the Society for the Blind, used the innovative procedure to eliminate blindness in a woman with end-stage age-related macular degeneration (AMD).
“Macular degeneration damages the retina and causes a blind spot in a person’s central field of vision. The telescopic implant restores vision by projecting images onto an undamaged portion of the retina, which makes it possible for patients to again see people’s faces and the details of objects located directly in front of them,” said Mark Mannis, professor at UC Davis.
The exact cause of dry macular degeneration is unknown, but the condition develops as the eye ages. The macula is made up of millions of light-sensing cells that provide sharp, detailed central vision. It is the most sensitive part of the retina, which is located at the back of the eye.
The retina quickly turns light into electrical signals and then sends these electrical signals to the brain through the optic nerve. The brain translates the electrical signals into images. If the macula is damaged, fine points are not clear.
In May, UC Davis cornea specialists Mannis and Jennifer Li implanted the miniature telescope, which is smaller than a pea, in the left eye of 89-year-old Virginia Bane, an artist who stopped painting four years ago when AMD took away her central vision. Bane is among the first 50 individuals to receive the implant. “I can see better than ever now,” Bane said.
