Clinical aspect of the eye

Clinically blockage can occur in any part of the tract.  A complete transection of the tract before the optic chiasm causes total blindness of the eye of that side.

            A lateral section at the optic chiasm will lead to an ipsilateral nasal hemianopsia.   A section posterior to the optic chiasm at the optic tract causes a left sided homonymous hemianopsia if the section is on the right side.

            A section across the optic chiasm in the sagittal plane leads to bitemporal heteronymous hemianopsia.   This usually occurs in pituitary tumor because of the close relationship between the hypophysis cerebri and the optic chiasm.
