Miotisis, also known as constriction of the pupil, is a condition in which the pupil becomes smaller than considered normal.
Signs and symptoms
Miotisis can cause several signs and symptoms, including:
- Blurred vision
- Pain
- Glare and sensitivity to light
- A headache, if caused by a brain injury
- Headache or facial pain, if caused by glaucoma
- Inability to fully open the eyelid
- Double vision
- Difficulty adapting vision in low light conditions
Causes
Miotisis commonly occurs as a result of eye surgery or medication, such as pilocarpine. However, miotisis can also occur from:
- Injury to the eye
- Use of certain medications
- Certain medical conditions
- Brain injury
- Cluster headaches
- Paralysis
- Glaucoma
When to see a doctor
If your miotisis does not improve or if it is caused by an injury to the eye, you should seek medical attention. If your miotisis is accompanied by other symptoms, such as headache, nausea, or vomiting, it is important to speak to an ophthalmologist or optometrist.
Treatment
Treatment for miotisis depends on the underlying cause. If miotisis is caused by medication or eye drops, the doctor may discontinue these eye drops or adjust your use. If the cause is injury or disease, treatment will depend on the specific condition.
