Scientists Restore Vision in Blind Mice Using Gene Therapy – Next, Human Testing
A variety of common eye diseases, including age-related macular degeneration and retinitis pigmentosa, damage the photoreceptors, impairing vision. But while the photoreceptors may no longer fully function, other retinal neurons, including a class of cells called bipolar cells, remain intact. The investigators identified a way for bipolar cells to take on some of the work of damaged photoreceptors.
