Strabismus (Crossed/Wandering Eye)
Strabismus occurs when both eyes are unable to properly team and align together. As a result, one or both eyes will appear to cross-in or wander-out of alignment. Any of these alignment problems will cause a deficit in depth perception.
Oftentimes, strabismus is interpreted as an eye muscle problem. However, it really is an eye-brain problem/connection which affects the eye muscles.
The word ‘Strabismus’ is an umbrella term used to describe an eye turn. However, the condition itself is often further classified by the direction of the eye turn, the frequency of the turn, and by which eye(s) are affected. These classifications include:
- Esotropia – Inward turning
- Exotropia – Outward turning
- Hypertropia – Upward turning
- Constant or Intermittent – The frequency in which a turn occurs
- Unilateral or Bilateral – Whether it involves one eye or both eyes
- Alternating– If the turning of an eye occurs in the left eye and other times in the right eye.
