MICROANATOMY

Detailed explanation-1: -Optic neuritis occurs when swelling (inflammation) damages the optic nerve-a bundle of nerve fibers that transmits visual information from your eye to your brain. Common symptoms of optic neuritis include pain with eye movement and temporary vision loss in one eye.

Detailed explanation-2: -Causes include infections and immune-related illnesses such as multiple sclerosis. Sometimes the cause is unknown. Optic nerve atrophy is damage to the optic nerve. Causes include poor blood flow to the eye, disease, trauma, or exposure to toxic substances.

Detailed explanation-3: -Optic nerve atrophy causes vision to dim and reduces the field of vision. The ability to see fine detail will also be lost.

Detailed explanation-4: -Damage to the optic nerve is irreversible because the cable of nerve fibers doesn’t have the capacity to regenerate, or heal itself, when damage occurs.

Detailed explanation-5: -Loss of vision in one eye over an hour or a few hours. Changes in the way the pupil reacts to bright light. Loss of color vision. Pain when you move the eye.
