We investigated optic nerve and geniculocalcarine tract (GCT) in acquired blindness (AB) using routine cranium magnetic resonance imaging and diffusion tensor imaging. Twenty individuals with AB were compared with 20 normally sighted (NS) individuals. The transverse diameters of optic nerves in NS were significantly bigger than the AB participants in T(1)WI maps. AB participants had higher mean diffusivity and transverse diffusivity and lower fractional anisotropy and primary diffusivity in the… CONTINUE READING
