The optic nerve of the eye is made up of over a million smaller nerves that connect the retina to the occipital lobe, reports the American Association for Pediatric Ophthalmology and Strabismus. This nerve is responsible for carrying images of what the eye sees to the brain.

Damage to this part of the eye may cause a variety of issues depending on the cause and extent of damage. Possible options for treating optic nerve related complications include the use of compresses, eye drops and surgery in serious cases.

Brain tumors are among the most common causes of optic nerve issues. Tumors may grow to extents that interfere with this nerve. Brain tumors are often accompanied by other symptoms that may include blurred vision.

Stroke refers to a condition in which the supply of blood to the brain is compromised. When this happens, certain cells related to the optic nerve may die and cause vision problems.

Infections may come as a result of fungi, bacteria or viruses. Most infections occur after surgery, certain diseases or injuries. Infections that occur close to the eye may cause damage to the optic nerve.
