Polycoria
Polycoria (pronunciation: /ˌpɒlɪˈkɔːrɪə/) is a medical condition characterized by the presence of more than one pupil in the eye. The term is derived from the Greek words 'poly' meaning 'many' and 'koros' meaning 'pupil'.
Definition
Polycoria is a rare condition where there are two or more true pupils in one eye, each with its own sphincter muscle and capable of constricting independently. This condition is often associated with other ocular abnormalities such as iris hypoplasia, iris coloboma, and corectopia.
Causes
The exact cause of polycoria is unknown. However, it is often associated with certain genetic disorders such as Axenfeld-Rieger syndrome and Peter's anomaly. It can also occur as a result of trauma or surgery to the eye.
Symptoms
The main symptom of polycoria is the presence of multiple pupils in one eye. This can lead to visual disturbances such as blurred vision, double vision, and glare. In some cases, polycoria may be asymptomatic and only detected during a routine eye examination.
Diagnosis
Polycoria is diagnosed through a comprehensive eye examination. This includes a detailed examination of the iris using a slit lamp. In some cases, additional tests such as optical coherence tomography (OCT) may be used to confirm the diagnosis.
Treatment
The treatment of polycoria depends on the severity of the symptoms and the presence of associated ocular abnormalities. In some cases, no treatment may be necessary. If the condition is causing significant visual disturbances, treatment options may include pupiloplasty, iridectomy, or the use of special contact lenses.
