Types of strabismus include:
- Pseudostrabismus: a false appearance of strabismus that occurs when the eyes are not looking in the same direction, often seen in infants and young children whose facial features have not fully developed and whose nasal bridge is broad and flat, giving the appearance of crossed eyes.
- Esotropia: a type of strabismus where one or both eyes turn inward toward the nose.
- Exotropia: a type of strabismus where one or both eyes turn outward away from the nose.
- Restrictive strabismus: a type of strabismus where a mechanical element hinders the eye's rotation and causes a restriction in eye movement.
Symptoms of strabismus may include eye strain, difficulty reading and writing, eye squinting, double vision, abnormal head tilt, lazy eye, and impaired binocular vision development.
