The first retinal gene therapy to be approved by the FDA was Voretigene neparvovec in 2017, which treats Leber's congenital amaurosis, a genetic disorder that can lead to blindness. These treatments also use subretinal injections of AAV vector and are therefore foundational to research in gene therapy for color blindness.
Cerebral achromatopsia. Cerebral achromatopsia is a type of color blindness caused by damage to the cerebral cortex of the brain, rather than abnormalities in the cells of the eye's retina.

2-9% males; <1% females. Congenital red–green color blindness is an inherited condition that is the root cause of the majority of cases of color blindness. It has no significant symptoms aside from its minor to moderate effect on color vision. [1] It is caused by variation in the functionality of the red and/or green opsin proteins, which are ...
