ORTHOPHORIA Meaning and
Definition
-
Orthophoria is a term used in ophthalmology to describe the normal or ideal alignment of the eyes when at rest and during fixation on a target. It refers to the condition in which the visual axes of both eyes converge on the object of regard without any deviation or misalignment. In orthophoria, both eyes work together harmoniously, allowing the brain to receive a single image and create three-dimensional perception.
When orthophoria is present, there is no manifest strabismus or tropia, which are conditions characterized by a constant or intermittent misalignment of the eyes. Orthophoria is the desired outcome for a healthy visual system, as it allows for efficient binocular vision and optimal depth perception.
It is important to differentiate between orthophoria and phoria, as the latter refers to a latent misalignment of the eyes that becomes evident only when inhibition mechanisms are weakened or disrupted. Orthophoria represents a state of ocular alignment that requires minimal effort and is maintained effortlessly by the visual system.
To assess the presence of orthophoria, various diagnostic tests are used, including the alternate cover test, prism cover test, and Maddox rod test. By conducting these examinations, ophthalmologists can detect if there is any deviation from the ideal alignment and can diagnose and treat any underlying eye muscle imbalance or binocular vision disorders that may be present.

The normal condition in which the tension of the extrinsic eye muscles is equal, the visual axes being therefore parallel.

Etymology of ORTHOPHORIA
The word "orthophoria" has its roots in the Greek language. It is derived from two Greek words: "orthos" meaning "straight" or "correct", and "phorein" meaning "to bear" or "to carry". When combined, these two words form "orthophoria", which can be roughly translated as "straight bearing" or "correct alignment". In the context of medicine and ophthalmology, orthophoria refers to the condition where the eyes are properly aligned and work together efficiently, allowing for binocular vision and stereopsis.
