Q & A: All you need to know about nerve loss and how to cope

Neurodegenerative vision is vision loss resulting from acquired brain injury and visual perception difficulties. The regions of the brain responsible for vision are damaged. The causes of vision loss are: stroke, brain tumor, head injury and infections such as meningitis. The damage to the occipital cortex, located in the back of the brain, processes the information and allows to see the distance, the shape, the movement and the color. The type and severity of vision loss depends on the area affected by the brain and its degree. According to the medical site "Betterhealth".

Symptoms depend on the type of visual impairment experienced by the individual and the area of ​​the brain affected, but may include:

• misty vision

• double vision

• Balance problems

Light phobia

• Difficult to understand and interpret what is considered

• partial loss of visual field

Among the many reasons may include:

Stroke: Part of the brain is damaged by bleeding or blockage in a blood vessel in the brain.

• Brain damage, for example after a car accident.

• Infection such as meningitis or cytomegalovirus.

• Lack of oxygen or heart attack, which can reduce blood flow to the brain.

• Disease such as brain tumor or multiple sclerosis.

This problem can not be corrected by glasses or contact lenses, because the cause is in the brain, not in the eyes.

Treatment includes symptom management and depends on the type of visual impairment. Treatment options include:

• Treatment of a basic brain injury: if the brain can recover from an injury, the person's vision can also improve.

• Determine the person's ability to walk with confidence on different surfaces.
