Detailed explanation-1: -The AVP originates in the retina, where the first order neuron begins with the bipolar cells [28]. The second order neuron extends from the retinal ganglion cells (RGCs) to the lateral geniculate nucleus (LGN) in the thalamus, and the third order neuron leaves the LGN en route for the visual cortex [28].

Detailed explanation-2: -There are four parts to the optic nerve: intraocular or optic nerve head, intraorbital, interosseus, and intracranial. The optic nerve is formed as axons of the retinal ganglion cells exit the retina through the optic disc.
