Which condition is synonymous with strabismus?

Phoria
Monocular vision
Tropia
Retinal defect

The correct answer is: Tropia

Strabismus is a condition characterized by the misalignment of the eyes, where both eyes do not look at the same point simultaneously. When one eye is focused on an object, the other eye may turn in, out, up, or down, resulting in a lack of coordination between the two eyes. The condition that is synonymous with strabismus is known as tropia. Tropia refers specifically to the observable deviation of one eye when both eyes are open, making it an essential aspect of strabismus. In contrast, the other terms provided represent different concepts. Phoria refers to a latent deviation of the eyes, visible only when one eye is covered, whereas both eyes can align properly when both are open. Monocular vision describes seeing with one eye only, which is not directly related to the alignment issues in strabismus. Retinal defect pertains to problems with the retina itself, rather than the coordination of eye movements. Therefore, identifying tropia as synonymous with strabismus reflects an understanding of the distinction between aligning and misaligning conditions of the eyes.
