APEA Pathophysiology: EENT Practice Exam – Prep & Study Guide

Strabismus is the condition characterized by the misalignment of the eyes, where they do not properly coordinate focusing on an object. This misalignment can manifest as one eye pointing straight ahead while the other may turn inwards, outwards, upwards, or downwards. It can affect depth perception and may lead to amblyopia if not addressed, as the brain may begin to ignore the input from the misaligned eye.

While amblyopia often results from strabismus, it refers specifically to decreased vision in one eye that is not attributable to a structural anomaly. Glaucoma, on the other hand, involves increased intraocular pressure leading to optic nerve damage, and hyperopia denotes a refractive error where distant objects may be seen more clearly than near objects, but neither of these conditions involves misalignment of the eyes. Thus, the defining characteristic of strabismus makes it the correct choice in this context.
