What does the term Strabismus refer to?

Strabismus refers specifically to a condition where the eyes do not properly align with each other when looking at an object. This misalignment is commonly referred to as being "cross-eyed." In strabismus, one eye may turn inward, outward, upward, or downward, while the other eye remains focused on a target. This condition can lead to issues such as double vision or poor depth perception, but the defining characteristic is the misalignment of the eyes themselves.

Blurred vision relates to problems with the clarity of sight, which is not a direct definition of strabismus. Involuntary eye movement refers to conditions such as nystagmus rather than the specific misalignment described by strabismus. Double vision, or diplopia, can occur as a result of strabismus, but it is a distinct symptom rather than a definition of the condition itself. Thus, the term "cross-eyed" is the most accurate description of strabismus.
