Exotropia might be corrected with base in which direction?

In
Up
Out
Down

The correct answer is: In

Exotropia is a type of strabismus, or misalignment of the eyes, where one eye turns outward. To correct this condition, the eye muscles must be adjusted so that the affected eye turns in toward the nose. This is referred to as a "base in" direction. Options B, C, and D are not correct because they would not fix the misalignment and could potentially worsen the condition. Turning the eye up, out, or down would not bring the eye back to its proper position and could lead to further strabismus or double vision.
