Miosis is a term in medicine that refers to the constriction of the pupil of the eye. It is generally caused by various factors such as exposure to bright light, use of certain medications, and certain diseases.
Causes[edit]
Miosis can be caused by a variety of factors. These include:
- Exposure to bright light: The pupils constrict in response to bright light in order to protect the retina from damage.
- Use of certain medications: Some medications, such as opioids, can cause miosis.
- Certain diseases: Diseases such as Horner's syndrome and Argyll Robertson pupil can cause miosis.
Symptoms[edit]
The primary symptom of miosis is the constriction of the pupils. This can result in reduced vision, especially in low light conditions. Other symptoms can include headache, nausea, and dizziness.
Treatment[edit]
Treatment for miosis depends on the underlying cause. If the miosis is caused by a disease, treating the disease will often resolve the miosis. If the miosis is caused by medication, it may be necessary to adjust the dosage or switch to a different medication.
