The condition where the eyes do not move or focus together is known as what?

Strabismus is the correct term for the condition in which the eyes do not align or move together. This misalignment can result in one eye looking at a different object than the other, leading to difficulties in focusing or seeing a single, clear image. Strabismus can manifest as esotropia, where one eye turns inward, or exotropia, where one eye turns outward. This condition can affect depth perception and, if untreated, can lead to amblyopia, commonly known as "lazy eye," where the brain starts ignoring input from one of the eyes.

The other conditions mentioned do not relate to the misalignment of the eyes. Otitis externa refers to an infection in the outer ear canal, glaucoma is a group of eye conditions that damage the optic nerve often associated with increased pressure in the eye, and atherosclerosis is a cardiovascular disease characterized by the buildup of fats, cholesterol, and other substances in and on the artery walls. Each of these conditions pertains to different bodily systems and has distinct implications and treatments unrelated to eye alignment.
