What does anisocoria refer to?

Anisocoria specifically refers to a condition characterized by unequal diameters of the pupils. This means that one pupil may be larger or smaller than the other, which can occur for various reasons, including neurological conditions, eye injuries, or as a benign anomaly in some individuals. The condition itself can be diagnostic, as healthcare providers will assess the pupil size during an examination to help identify potential underlying health issues.

Recognizing anisocoria is crucial because it can indicate serious conditions, such as increased intracranial pressure or nerve damage. Understanding this term is vital for anyone in the medical field, as it can influence assessments and subsequent treatment plans. Other options, while they reflect various medical conditions, do not relate to the concept of pupil size and therefore do not define anisocoria.
