Pupil Diameter Unequal refers to a condition where the size of the pupils in a person's eyes is noticeably different. The pupil is the round, black opening at the center of the iris that controls the amount of light entering the eye. In a normal, healthy eye, both pupils should be of equal size and respond similarly to changes in light intensity.
When one or both pupils are unequal in size, it could indicate an underlying medical condition or injury affecting the nerves, muscles, or blood vessels that control pupil dilation. Pupil Diameter Unequal is often a symptom or sign of several medical conditions, including but not limited to, anisocoria (persistent unequal pupil size), Horner's syndrome (a disruption of the sympathetic nerves in the face and neck), Adie's syndrome (a condition affecting the nerves that control pupil size and constriction), traumatic brain injury, certain medications or eye drops, or a variety of eye disorders.
The presence of Pupil Diameter Unequal may suggest the need for further medical evaluation and diagnostic tests to identify the underlying cause. An ophthalmologist or optometrist typically examines the eyes and performs various tests, including shining a light into the eye and assessing the response of the pupils to determine the cause and severity of the inequality.
Overall, Pupil Diameter Unequal is a medical term used to describe the condition where the sizes of the pupils in an individual's eyes are noticeably different, and it often indicates an underlying medical issue that requires medical attention and further evaluation.
