Your baby's eyes might shake due to a condition called nystagmus. It's characterized by involuntary, repetitive eye movements. Nystagmus appearing in very young babies is often referred to as early-onset or congenital nystagmus.
Understanding Nystagmus in Infants
Here's a breakdown of why this shaking may be happening:
- Developmental Issues: The most common reason is a developmental problem affecting the eyes, the brain, or the connections between them. This impacts the visual system's ability to stabilize images.
- Congenital vs. Acquired:
- Congenital Nystagmus: This type is present at birth or develops within the first few months of life. The exact cause can be difficult to pinpoint.
- Acquired Nystagmus: This type develops later in childhood or adulthood and is often linked to underlying neurological conditions, injuries, or medications.
Possible Causes of Congenital Nystagmus
While a specific cause isn't always identified, some factors that can contribute to congenital nystagmus include:
- Genetic Factors: Nystagmus can be inherited. If there's a family history of the condition, your baby might be more likely to have it.
- Eye Conditions: Certain eye conditions present at birth, such as congenital cataracts or albinism, can be associated with nystagmus.
- Neurological Issues: In some cases, neurological problems affecting brain development or function can lead to nystagmus.
- Idiopathic: Sometimes, the cause of congenital nystagmus remains unknown (idiopathic).
What to Do Next
It's crucial to consult with a pediatrician or pediatric ophthalmologist if you notice your baby's eyes shaking. They can perform a comprehensive eye exam and neurological evaluation to determine the underlying cause and recommend appropriate management or treatment strategies. Early diagnosis and intervention can help maximize your child's visual potential and overall development.
