Strabismus is best described as?

Strabismus is best described as an abnormal alignment of the eyes, where the eyes do not properly align with each other when looking at an object. This condition can manifest in various forms, such as one eye deviating while the other remains straight, leading to issues with depth perception and binocular vision. When the eyes are misaligned, the brain may have difficulty processing visual information, which can sometimes result in double vision or amblyopia (lazy eye) if not addressed.

The other options do not accurately capture the essence of strabismus. The inability to see objects clearly at a distance pertains to refractive error conditions such as myopia or hyperopia, while scar tissue formation on the retina is related to retinal pathology rather than eye alignment. Farsightedness, or hyperopia, also does not involve the alignment of the eyes but rather refers to a condition where distant objects are seen more clearly than near ones. Thus, the most accurate description of strabismus focuses on the misalignment of the eyes.
