Paradoxically, the photoreceptor cells in our retinas release more of their neurotransmitter, glutamate, in the dark, when there is nothing to see, than they do in the light. This is doubly surprising ...

In this form of LCA disease, photoreceptor cells cannot respond to light because a gene called RPE65 does not properly produce a protein ...
