Examples
A pituitary tumour may compress the optic tracts or the optic chiasm of the optic nerve (II), leading to visual field loss.
A person may not be able to see objects on their left or right sides ( homonymous hemianopsia ), or may have difficulty seeing objects on their outer visual fields ( bitemporal hemianopsia ) if the optic chiasm is involved.
