Orthophoria
Orthophoria
Orthophoria (pronounced: or-tho-for-ia) is a term used in optometry and ophthalmology to describe a condition where the eyes are properly aligned with each other and work together to focus on an object.
Etymology
The term "Orthophoria" is derived from the Greek words "orthos" meaning straight, and "phoros" meaning bearing or carrying. Thus, it literally translates to "straight bearing" or "straight carrying".
Definition
Orthophoria is a state of the eyes where there is no strabismus or misalignment when both eyes are open and looking at an object. In this condition, both eyes are perfectly aligned and there is no tendency for one eye to deviate or turn away from the target when the other eye is covered.

Diagnosis
Orthophoria is diagnosed through a comprehensive eye examination by an optometrist or ophthalmologist. The examination includes tests to assess eye alignment and focusing ability, such as the cover test and the uncover test.
Treatment
As orthophoria is a normal condition where the eyes are properly aligned, no treatment is necessary. However, regular eye examinations are recommended to monitor eye health and detect any potential issues early.
