What Is Nystagmus?
Nystagmus is condition that usually affects both eyes, It is an involuntary and rhythmic motion of the eyes, either a circular motion, or up and down or side to side. It occurs with a variety of conditions. The movements can last only a few seconds or they can be permanent.
200 cases a day
Approximately 600,000 people in the UK currently have sight loss caused by AMD, and 70,000 new cases are diagnosed every year (that’s nearly 200 cases a day). It is the most common cause of sight loss in the developed world and the third most common globally.
Symptoms of nystagmus
The main symptom experienced by patients with nystagmus is the sensation that the world around them is constantly moving (this is know as oscillopsia).
Often nystagmus can be present together with problems affecting the brain or the inner ear. Patients with this correlation will also experience vertigo, loss of balance, and dizziness.
Blurry vision and jumping vision are two other common symptoms.
Causes of nystagmus
- Nystagmus can be congenital.
- It can also be cased by diseases affecting the balance mechanisms in your inner ear or the brainstem (the back part of your brain).
- Other neurodegenerative conditions such as multiple sclerosis can also be associated with nystagmus symptoms.
Treatment for nystagmus
Some types of nystagmus, especially in children, are temporary and can improve with time.
Glasses and contact lenses do not correct the nystagmus, but in some cases they can improve vision. Large-print books and magnifying vision aids can also be helpful to cope with the condition.
Surgery that repositions the muscles that move the eyes is also an option. This is helpful because it will reduce the need to turn your head to see better, but it doesn’t cure nystagmus itself.
