MICROANATOMY

Detailed explanation-1: -The optic nerve is critical to your vision. It’s an extension of your central nervous system, which includes your brain and spine. The optic nerve transmits electrical impulses from your eyes to your brain. Your brain processes this sensory information so that you can see.

Detailed explanation-2: -Visual field defects: Since the optic nerve is responsible for vision, any lesions along the length of the optic nerve, optic chiasm, optic tract, or optic radiation will present with different visual field defects.

Detailed explanation-3: -Description. The optic nerve is a bundle of more than 1 million nerve fibers. Also known as the second cranial nerve or cranial nerve II (CNII), it is the second of several pairs of cranial nerves. It transmits sensory information for vision in the form of electrical impulses from the eye to the brain.

Detailed explanation-4: -The optic nerve is a bundle of more than 1 million nerve fibers that carry visual messages. You have one connecting the back of each eye (your retina) to your brain. Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs.

Detailed explanation-5: -Made of nerve cells, the optic nerve is located in the back of the eye. Also known as the second cranial nerve or cranial nerve II, it is the second of several pairs of cranial nerves.
