What is the name for the condition of having naturally occurring uneven pupil size?

Anisocoria is the medical term that describes the condition where a person has pupils of unequal size. This condition can occur naturally in some individuals without any underlying pathology or may indicate the presence of a neurological issue or other medical conditions. In some cases, anisocoria is a benign finding and doesn't affect visual function, but it is important to assess it in the context of other symptoms and potential causes.

Strabismus refers to a condition where the eyes do not properly align with each other when looking at an object, which is unrelated to pupil size. Hyperopia is a vision condition, commonly known as farsightedness, where distant objects can be seen more clearly than nearby ones. Amblyopia, also known as lazy eye, is a vision development disorder where an eye fails to achieve normal visual acuity, which again does not involve pupil size.

Understanding these definitions clarifies why anisocoria is the correct choice and highlights the unique characteristics associated with each term.
