Pupillary disorders refer to any abnormality or dysfunction associated with the pupillary response, which is the adjustment of the size of the pupils in the eyes. The pupils are the circular openings in the center of the iris that control the amount of light entering the eye.
There are various types of pupillary disorders, each involving a different abnormality or dysfunction. One such disorder is called anisocoria, which is characterized by unequal pupil size. This can be a benign condition resulting from natural variations in pupil size between individuals, or it can be a symptom of an underlying health condition such as Horner's syndrome, nerve damage, or an eye injury.
Another pupillary disorder is known as miosis, which refers to abnormal constriction or narrowing of the pupils. Miosis can be caused by various factors including certain medications, neurological disorders, or exposure to certain substances like opioids or nicotine.
On the other hand, mydriasis is a pupillary disorder characterized by the abnormal dilation or enlargement of the pupils. Mydriasis can occur due to underlying health conditions like damage to the sympathetic nervous system, certain medications, or as a result of eye trauma.
Pupillary disorders can affect vision and may be indicative of an underlying health condition, making their evaluation important for proper diagnosis and treatment. Ophthalmologists or eye specialists are typically involved in the assessment and management of pupillary disorders.
