Pupillary size inequality refers to an abnormal condition in which there is a difference in the size of the pupils in an individual's eyes. The pupils are the black circular openings in the center of the iris, responsible for regulating the amount of light that enters the eye. In a healthy individual, the size of the pupils is generally equal.
Pupillary size inequality can occur due to various underlying causes or conditions, including neurological disorders, eye diseases, trauma, or certain medications. It is often an indication of dysfunction or damage to the nerves and muscles that control the constriction and dilation of the pupils.
The measurement of pupillary size inequality can be done by comparing the diameter of each pupil. Anisocoria is a term used to describe unequal pupil size, with the larger pupil referred to as the "dilated" pupil, and the smaller pupil as the "constricted" pupil. The magnitude of inequality can vary, ranging from a subtle difference that is barely noticeable to a significant difference that is easily observable.
Pupillary size inequality may cause a variety of symptoms depending on the underlying cause and the degree of difference between the pupils. These symptoms can include blurred vision, eye pain, sensitivity to light, double vision, and even headaches in some cases.
When pupillary size inequality is observed, it is crucial to seek medical attention to determine and address the underlying cause. Ophthalmologists and neurologists are healthcare professionals who specialize in diagnosing and managing conditions related to pupillary abnormalities.
