What does the term "exophoria" refer to in eye alignment?

Exophoria refers to a type of strabismus where there is a tendency for one eye to turn outward when both eyes are open and focused. It represents a latent deviation; the eyes are usually aligned when both eyes are being used together, but when one eye is covered or during fatigue, the eye may drift outward.

The outward turning characteristic of exophoria is significant in diagnosing and treating ocular alignment issues, as it can indicate imbalances in the muscles or neurological control responsible for eye positioning. Understanding exophoria is crucial for ophthalmic assistants and healthcare professionals, as they may need to assess this condition during vision exams and provide appropriate referrals or treatment options based on their findings.
