Post-Stroke Vision Loss
Post-Stroke Vision Loss
Stroke is typically associated with brain damage caused by vascular blockage or bleeding. Post-stroke vision loss is often a sudden occurrence in one or both eyes. It can affect central vision, peripheral vision, or both, profoundly influencing an individual's ability to see clearly.
Causes:
Optic Nerve Damage: The optic nerve may sustain damage during or after a stroke, leading to vision loss.
Retinal Damage: The retina, responsible for detecting light and transmitting nerve impulses to the brain, can be damaged due to altered blood flow during a stroke.
Weakness in Eye Muscles: Post-stroke, weakness in eye muscles may develop, affecting eye movements and focus.
Symptoms:
- Sudden, unilateral, or bilateral vision loss.
- Blurred or distorted vision.
- Changes in color perception.
Treatment and Rehabilitation:
The treatment of post-stroke vision loss depends on the underlying causes. The primary goal is to improve eye health and minimize vision loss. Rehabilitation programs focus on regaining visual abilities and adapting to daily life activities.
