Scientists from the University of California have found a way to restore sight in adult mice with congenital blindness.
The study involves injecting synthetic retinoid treatments directly into the eyes of LCA patients. LCA, or Leber congenital amaurosis, is a group of hereditary diseases that causes vision disability at birth. The scientists thought that for the brain’s central circuits to wire themselves properly, those signals had to be received during childhood.
While previous studies showed that the treatment can help restore some vision loss in children, its effect on adults is still unclear. Surprisingly, the current research on rodents indicates that the restoration of visual function at the level of the brain was much greater than expected.
The recent discovery could pave the way for restoring sight in adults with congenital blindness.
