Congenital Nystagmus: Causes and Symptoms
Congenital nystagmus is a rare eye condition that affects about 1 in 1,000 people. It is a type of involuntary eye movement that occurs from birth or within the first few months of life. The exact cause of congenital nystagmus is not fully understood, but it is believed to be caused by abnormal development of the eye or the brain's control of eye movements.
There are two types of congenital nystagmus: sensory and motor. Sensory nystagmus is caused by poor vision or other visual problems, while motor nystagmus is caused by problems with the nerves or muscles that control eye movements.
Symptoms of Congenital Nystagmus
The main symptom of congenital nystagmus is involuntary eye movements that can be horizontal, vertical, or rotary. These movements can vary in speed and intensity and can be worsened by stress, fatigue, or anxiety. People with congenital nystagmus may also experience other symptoms, such as:
- Reduced visual acuity
- Difficulty with depth perception
- Sensitivity to light
- Head tilting or nodding
Congenital nystagmus is usually diagnosed during infancy or childhood. An eye doctor will perform a comprehensive eye exam and may order additional tests, such as an electroretinogram or a brain MRI, to determine the cause of the nystagmus.
Causes of Congenital Nystagmus
As mentioned earlier, the exact cause of congenital nystagmus is not completely understood. However, researchers believe that several factors can contribute to the development of this eye condition, including:
- Abnormal development of the eye or the brain's control of eye movements
- Inherited genetic mutations
- Illness or injury during pregnancy or childbirth
- Exposure to certain drugs or toxins during pregnancy
Congenital nystagmus is a lifelong condition that cannot be cured. However, there are several treatments available that can help manage the symptoms and improve visual function. If you or your child has been diagnosed with congenital nystagmus, it is important to work closely with an eye doctor or a specialist who can provide the best possible care.
