Measurements of eyes and optic nerves of blind and normal mice were taken at ages ranging from 1-60 days. The mice used were from a Bagg albino strain in which a dominant mutation for blindness had occurred. The size of the optic nerve appears to be dependent upon the development of the eye. Optic nerves from blind eyes are smaller than those from normal eyes, and optic nerves from blind eyes without a lens and with a folded retina are smaller than those from eyes with a lens, even though the lens is vacuolated and the cornea is thickened.
