Can a lazy eye move?

Published in Eye Health 2 mins read

Yes, a lazy eye (amblyopic eye) can move, and often does. It frequently wanders inward or outward.

Amblyopia, commonly known as lazy eye, is a condition characterized by reduced vision in one eye due to abnormal visual development early in life, typically from birth up to around age 7. While the eye itself is physically capable of movement, the brain favors the stronger eye, leading to the weaker eye's underdevelopment and potential misalignment. This misalignment can manifest as the lazy eye drifting or wandering, which is why it appears lazy.

Here's a breakdown:

  • Misalignment: The primary characteristic associated with a lazy eye's movement is its misalignment with the other eye.
  • Wandering: This misalignment can cause the eye to wander inwards (esotropia) or outwards (exotropia).
  • Not Constant: The wandering or drifting may not be constant; it can occur intermittently.

Why does this movement happen?

The brain's preferential use of the stronger eye results in the weaker eye's visual cortex not developing properly. This affects the coordination and alignment of the eyes. The brain essentially "ignores" the input from the lazy eye, further hindering its development and proper functioning, which includes coordinated movement.

In summary: A lazy eye is capable of movement, and its tendency to wander or drift is a common symptom of the condition. This movement, or lack of coordinated movement, is a result of the abnormal visual development associated with amblyopia.
