Medical Terms - Anisocoria
A variation of 0.5 to 2 mm in pupil diameter. Anisocoria is present in around 2% of individuals, in whom the disparity in pupil size remains stable throughout time and regardless of variations in light conditions. Nonetheless, if anisocoria arises from the fixed dilation or constriction of one pupil, or from a delayed or compromised constriction of one pupil in reaction to light, it may signify neurologic pathology. Assessing whether the aberrant pupil is dilated or constricted facilitates diagnosis.
