Final answer:
Exotropia is a type of strabismus characterized by the outward drifting of one or both eyes, which is distinct from vision problems that affect the eye's focusing ability like myopia, hyperopia, astigmatism, and presbyopia.
Step-by-step explanation:
The form of strabismus in which one eye or both eyes drift outward away from the nose is known as exotropia. This condition is a type of strabismus and can affect either eye or both. Unlike other vision problems such as hyperopia (farsightedness), myopia (nearsightedness), astigmatism (uneven focus), or presbyopia (age-related difficulty focusing on close objects), exotropia involves a visible misalignment of the eyes rather than an issue with the eye's ability to focus light directly onto the retina. As with other forms of strabismus, early detection and treatment are important for preventing complications such as amblyopia (lazy eye), where the brain favors one eye over the other, leading to vision loss in the unfavored eye.
