Color Blindness: There is a Cure on the Horizon

If you have trouble seeing certain colors like red, green, blue, or yellow, you may now be in luck. A single injection treatment for color blindness may begin human trials as soon as 2017.

Color blindness is actually not a form of blindness at all, but a deficiency in the way you see color. Instead of colors being easily distinguishable, certain colors – like blue and yellow or red and green - appear washed out and are easily confused with other colors, depending on the type of color vision deficiency you have. Red-green color deficiency is the most common form of color blindness.

Color blindness or, more accurately, color vision deficiency, is a hereditary condition that affects males more than females, because the genes responsible for inherited color blindness are on the X chromosome.

At the University of Washington, two professors of ophthalmology - Jay Neitz, PhD and Maureen Neitz, PhD - have had success treating color blindness in animals. The new treatment that they are testing uses an injection of an adeno-associated virus, which is a virus that targets genetic material in the cone cells of the retina. The Neitz’s hope to begin human trials with this treatment in 2017. They are also developing similar treatments for other, more serious retinal problems that may be tested in the future.

If successful, color blindness could be reduced or cured with a single injection from an eye doctor.
