Corectopia is a medical condition where the pupil of the eye is off-center and not in its usual position. There are several synonyms for this condition, including heterocoria, anisocoria, and pupil asymmetry. Heterocoria is the presence of different sized pupils, while anisocoria is unequal pupil sizes. Pupil asymmetry refers to instances where one pupil is not in the same position as the other. Other synonyms for corectopia include pupillary deviation, pupil displacement, and ocular dysmorphia. While corectopia can be a sign of an underlying medical condition, it can also be congenital or occur as a result of injury or trauma to the eye.
