An outward eye deviation is known as which of the following?

  1. Hypertropia

  2. Hypotropia

  3. Esotropia

  4. Exotropia

The correct answer is: Exotropia

An outward deviation of the eye is referred to as exotropia. This condition occurs when one or both eyes turn outward, away from the nose. It is a form of strabismus, which is a misalignment of the eyes, and can occur intermittently or be constant. In contrast, hypertropia refers to an upward deviation of the eye, while hypotropia indicates a downward deviation. Esotropia, on the other hand, is characterized by an inward turning of one or both eyes. Therefore, exotropia is specifically associated with the outward positioning of the eyes, making it the correct answer to identify this condition.
