Expert Solution
Introduction
The optic nerve pathway is a complex pathway leading to the sensation of vision. The optic nerves arising from the left and the right side have a decussation at the optic chiasm. They cross over to form the optic tract which after crossing the lateral geniculate nucleus becomes the optic radiation. According to the level of lesion in the pathway, there are varied effects on the eye.
