These conditions require specific care to manage the symptoms and improve patient outcomes.

This may be due to trauma, Horner’s syndrome or another cause. This may be caused by:Īn abnormally small pupil, known as a miotic pupil, may occur when the eye becomes inflamed. The mydriatic pupil or the one which is larger in size is more likely to be abnormal if the difference in size is exaggerated by bright lighting.Īn abnormally large pupil, known as a dilated or mydriatic pupil, occurs when the iris is not able to constrict as usual in response to bright light. It is likely to be abnormal if the difference in size becomes more noticeable in the dark. This can be a normal finding, but can also represent a life-threatening condition such as some causes of Horners. The miotic pupil is the one which is smaller in size. Overall health of the front and back portion of the eyesĭuring the investigative process, it is important to establish which pupil is abnormal.Pupil size and reaction to lighting changes.The extent of pupil size difference in a dimly-lighted environmentĪ pediatric ophthalmologist will usually perform a number of tests to examine the extent and implications of anisocoria, including an evaluation of:.The extent of difference in the pupil size in a brightly-lighted environment.Any related incident at the time when anisocoria first presented.There are certain characteristics about anisocoria that can help physicians to understand whether the sign is indicative of an underlying condition.
