Scientists at the National Eye Institute (NEI) have recently reversed congenital blindness in mice. The breakthrough methodology could potentially lead to better treatment for eye impairments in humans.

The recent research by scientists involves changing supportive cells in retinal tissue. The cells of interest are known as Muller glia (MG), in which researchers developed a method to reprogram the retina cells into photoreceptor cells known as rods, reports Times Now.

Mammalian eyes contain rods and cones, both carrying out separate functions imperative for vision. Rods are receptor cells in the eye. According to Thomas N. Greenwell, Ph.D., NEI program director for retinal neuroscience, rods allow us to see in low light, “but they may also help preserve cone photoreceptors, which are important for color vision and high visual acuity.”
