Hemianopia

Below we explain what Hemianopia is, what the symptoms and risk factors are and any available treatment options.

Hemianopia is the loss of sight in one half of the field of vision, usually to the same side in both eyes.  It is due to damage to the optic pathways from the eyes to the brain, often the result of stroke or brain injury . High blood pressure is a risk factor . Some brain growths can present in this way.

Symptoms

• Loss of sight to one side, but this may not be recognised by the affected person .
• Inability to read, especially if the loss is to the right side .
• There may be associated loss of visual awareness.
• Bumping into furniture etc. to one side only.

Assessment

• If you are at risk of stroke, your risks increase for Hemianopia.
• High blood pressure or an abnormal heart rhythm.
• People over the age of 55.

Treatment

Early medical care may allow some recovery soon after the onset . Treatment is of the underlying cause. Visual rehabilitation training can be very helpful , but optical aids are rarely useful.
