Changes in those genes can lead to many eye conditions, including glaucoma, cataracts, and inherited retinal disorders. If your child has an inherited retinal disorder, they might benefit from genetic testing. It can help determine a diagnosis and how their ...

Optic nerve regeneration: One approach doesn’t fit all
Getting a damaged optic nerve to regenerate is vital to restoring vision in people blinded through nerve trauma or disease. A variety of growth-promoting factors have been shown to help the optic nerve’s retinal ganglion cells regenerate their axons, but we are still far from restoring vision. A new study on optic nerve regeneration, published ... Read More about Optic nerve regeneration: One approach doesn’t fit all
Drug ‘cocktail’ could restore vision in optic nerve injury
When Zhigang He, PhD, started a lab at Boston Children’s Hospital 15 years ago, he hoped to find a way to regenerate nerve fibers in people with spinal cord injury. As a proxy, he studied optic nerve injury, which causes blindness in glaucoma — a condition affecting more than four million Americans — and sometimes ...
