Which term specifically refers to an outward turning of the eye?

The term that specifically refers to an outward turning of the eye is exotropia. This condition occurs when one or both eyes deviate outward instead of aligning properly with the other eye.

In the context of ocular conditions, exotropia can lead to issues with depth perception and binocular vision, as the eyes are not working together as they should. It is essential to understand this term in the context of strabismus, which encompasses various types of misalignments of the eyes.

Hypertropia describes an upward deviation of the eye, while esotropia is characterized by an inward turning of the eye. Antimetropia refers to a condition where the two eyes have different refractive powers but does not specifically relate to the turning or misalignment of the eyes. Thus, exotropia is the precise term used to denote outward turning, making it the correct choice in this case.
