- Esotropia:

- Illustrated in the first image (A) with the left eye turned inward.

- Exotropia:
- Characterized by an outward deviation of the eyes.
- Illustrated in the second image (B) with the left eye turned outward.
- Also shown in the fourth image (B) where the covered eye drifts outward when uncovered.
