Overview & Considerations
Occasionally, differing pupil size is inherited and there is no underlying disorder. If other family members also have this condition, then pupil size is probably genetic and is nothing to worry about.
Occasionally, for unknown reasons, pupils may differ in size. If there are no other symptoms and if the pupils return to normal, then the transient condition is nothing to worry about.
Head injuries that cause differing pupil sizes are usually curable with early recognition of danger signs and medical treatment. Complications, however, can be life-threatening or cause permanent disability.
