With LCA Gene Therapy, a Rare Glimpse of the Adult Brain Adapting to New Experience

When people lose the ability to see, how do the visual parts of the brain change in response? And if they regain their sight, are the changes reversed?
Children who slept near a cooking fire were four times as likely to develop severe trachoma compared with children who slept in ventilated rooms without cooking fires. This child’s severe trachoma led to loss of vision in his left eye. Photo courtesy of Raul Vasquez/Orbis.
