MEDICAL PHYSIOLOGY

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: -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-3: -There are no effective treatments to regenerate nerve cells or to restore connections between the eye and brain once the optic nerve is lost. This is a major barrier in the field and one that must be overcome, given the substantial number of patients suffering from optic neuropathy-associated blindness.

Detailed explanation-4: -Unfortunately, there is no effective treatment for optic atrophy. Once the nerve fibers in the optic nerve are lost they never heal or grow back. However, early diagnosis and treatment of the underlying causes of optic atrophy can help prevent further damage from the disease.
