Which of the following describes an abnormal eye position?

An abnormal eye position in dogs can manifest in various ways, and each of the conditions listed reflects a different type of abnormality. Enophthalmos refers to the retraction of the eye into the orbit, giving the appearance of sunken eyes. This condition can arise from issues such as dehydration, loss of orbital fat, or trauma.

Exophthalmos, on the other hand, describes a condition where the eye is protruding or bulging from the orbit, often associated with conditions such as tumors, inflammation, or hyperthyroidism. This can lead to various complications due to the increased pressure and potential to affect the surrounding tissues.

Strabismus is characterized by a misalignment of the eyes, where the eyes do not properly fixate on the same point, which can be due to neurological issues or muscular problems. This misalignment can significantly impact a dog's vision and depth perception.

Each of these conditions indicates an alteration from the normal position of the eye and can be indicative of underlying health issues. Thus, the correct answer is that all of the conditions described contribute to an abnormal eye position.
