Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3 ...
This treatment was found to prolong photoreceptor cell survival for several months [31] and also the number of photoreceptor was 2.5 fold higher in AAV-Mertk- treated eyes compared with controls 9 weeks after injection, also they found decreased amount of debris in the subretinal space.
