Hemianopia

Hemianopia is a medical condition characterized by the loss of vision or blindness in half the visual field of one or both eyes. It is often caused by stroke, brain injuries, tumors, or neurological disorders.

Causes

Hemianopia can be caused by a variety of conditions, including:

• Stroke: This is the most common cause of hemianopia. A stroke occurs when the blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients.

• Brain injuries: Trauma to the brain can also cause hemianopia. This can occur as a result of a direct blow to the head, violent shaking, or a penetrating injury.

• Tumors: Brain tumors can cause hemianopia by pressing on or damaging the visual pathways in the brain.

• Neurological disorders: Certain neurological disorders, such as Multiple sclerosis, can cause hemianopia.

Symptoms

The primary symptom of hemianopia is the loss of vision in half of the visual field. This can occur in one or both eyes. Other symptoms may include:

• Difficulty reading
• Difficulty driving
• Difficulty recognizing faces
• Difficulty navigating through unfamiliar environments

Treatment

Treatment for hemianopia depends on the underlying cause. This may include:

• Medication: Certain medications may be used to treat the underlying cause of the hemianopia.

• Surgery: In some cases, surgery may be required to remove a tumor or to repair damage to the brain.

• Rehabilitation: Rehabilitation therapies, such as visual field expansion therapy or compensatory strategies, can help individuals adapt to their visual loss.
