What common condition affects the eye when one eye is misaligned, impacting binocular vision?

Strabismus is the correct condition that affects the eye when one eye is misaligned, which can significantly impact binocular vision. This misalignment can lead to a range of visual problems, including double vision and impaired depth perception. In a healthy visual system, both eyes work together to provide a single, three-dimensional image. However, when one eye is misaligned as seen in strabismus, the brain may suppress the image from the misaligned eye to avoid confusion, potentially resulting in a lack of proper visual development and depth perception issues.

In contrast, presbyopia is a condition related to aging and affects the ability to focus on close objects, but it does not involve misalignment of the eyes. Diabetic retinopathy is a complication of diabetes that affects the retina, leading to vision issues but does not specifically pertain to eye misalignment. Cataracts involve clouding of the lens of the eye, causing blurred vision but also do not involve the misalignment of the eyes. Each of these conditions affects vision in different ways, but strabismus is uniquely characterized by the misalignment of one or both eyes and its resulting impact on binocular vision.
