Which terms indicate the direction of deviation in tropia or phoria?

Eso, Exo, Hyper, and Hypo
Alpha, Beta, Gamma
Neurological, Optical, Physiological
Short, Long, Medium

The correct answer is: Eso, Exo, Hyper, and Hypo

The correct answer is the terms Eso, Exo, Hyper, and Hypo, which are used to describe the specific directions of deviation in latent or manifest strabismus, known respectively as phoria and tropia. These terms have specific meanings in the context of eye alignment. "Eso" indicates an inward deviation of the eye towards the nose, commonly referred to as esotropia when it is a constant misalignment. "Exo" represents an outward deviation of the eye away from the nose, known as exotropia when persistent. "Hyper" describes a situation where one eye is positioned higher than the other, indicating hypertropia, while "Hypo" denotes one eye being lower than the other, referred to as hypotropia. Each of these terms helps practitioners diagnose and communicate different eye alignment issues, making them essential in the optometric and ophthalmologic fields for evaluating and managing conditions related to eye muscle function. The other options listed do not pertain to the direction of eye deviation and therefore are not relevant in this context.
