What does the suffix phoria mean?

The suffix "-phoria" means "tendency to turn" or "a condition of being turned." It's often used in the context of eye movements.

Here's how it works:

* Phoria: This refers to a latent tendency of the eyes to turn in a specific direction. It's a hidden or potential condition that only becomes apparent under specific conditions.

* -phoria: This suffix indicates the direction of the tendency.

For example:

* Esophoria: Tendency of the eyes to turn inward.

* Exophoria: Tendency of the eyes to turn outward.

* Hyperphoria: Tendency of one eye to turn upward.

* Hypophoria: Tendency of one eye to turn downward.

Therefore, "-phoria" describes a specific ocular misalignment that may not be immediately noticeable, but can affect a person's vision and eye health.
