Strabismus (cont\'d)

Strabismus & Amblyopia

Understanding the Difference

Strabismus

Strabismus is classified by the direction the eye turns:

• Inward turning is called esotropia

• Outward turning is called exotropia

• Upward turning is called hypertropia

• Downward turning is called hypotropia
  ​​​​​​​

Other classifications of strabismus include:

• The frequency with which it occurs, either constant or intermittent

• Whether it always involves the same eye (unilateral)

• If the turning eye is sometimes the right eye and other times the left eye (alternating)

Amblyopia

Signs and symptoms of amblyopia include:

• An eye that wanders inward or outward

• Eyes that may not appear to work together

• Poor depth perception
