Exotropia (pronounced: ex-oh-TROH-pee-uh) is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more than one of the six extraocular muscles.
Etymology
The term "exotropia" comes from the Greek words "exo" meaning "outward" and "tropos" meaning "turn".
Types of Exotropia
There are several types of exotropia, including:
- Intermittent Exotropia: This is the most common type of exotropia. It occurs intermittently, often when the person is daydreaming, ill, or tired.
- Congenital Exotropia: This type of exotropia is present at birth or develops within the first six months of life.
- Sensory Exotropia: This type of exotropia develops as a result of poor vision in one eye.
- Consecutive Exotropia: This type of exotropia occurs after surgery to correct esotropia.
Symptoms
Symptoms of exotropia can include:
- Eyes that look in different directions

- Difficulty with depth perception
- Closing or covering one eye, especially in bright sunlight
Treatment
