They may be able to discuss finding an alternative treatment with the doctor who prescribed the drug. Treatment for mydriasis is determined by what caused the condition in the first place. Treatment approaches will try to protect the full functionality of the eyes.
For example, if pupil dilation is caused by a reaction to medication, even though several drugs could quickly get the pupils back to normal size, many providers would simply recommend waiting for the effects of the drug to wear off and avoiding it in the future. When mydriasis is caused by injuries to the brain and eyes, more intense treatments come into play. In extreme cases, a person may require surgery to repair the damage done to the nerves or eye structures. Individuals may wear an eye patch while their eyes heal.
Low doses of Pilocarpine, a medication typically used to treat glaucoma, can also be used to help constrict, or narrow, the pupils. If a person notices their pupils are dilated without a clear reason, they should see a doctor or an eye specialist. If mydriasis develops after an injury to the eyes or head, a person should seek medical treatment urgently.
There are many causes for mydriasis, some of which are temporary and will wear off within hours, such as a response to medications. In serious cases, a person can have surgery to correct the underlying cause of an enlarged pupil, though this is not always necessary.

Medically reviewed by Ann Marie Griff, O. What is mydriasis? Causes Symptoms Complications Treatments Seeing a doctor Outlook Mydriasis is the medical term for an unusual dilation or widening of the pupils. Share on Pinterest Mydriasis causes unusual dilation of the pupil. Dilated pupils are pupils that are larger than normal.
They are sometimes called dilated eyes. The size of your pupils is controlled by tiny muscles in the colored part of your eye iris and the amount of light reaching your eyes.
In bright light, your pupils constrict get smaller to prevent too much light from entering your eyes. In dim lighting, your pupils dilate get larger to allow more light in. Normal pupil size generally ranges from 2. To some degree, pupil size tends to get smaller with age.
In one study of Americans ages 18 to 34 years, average pupil sizes in three different lighting conditions were found to be:. A dilated pupil can sometimes still react to light — that is, get smaller in bright light or when a light is shined at the eye. A large pupil that is completely unresponsive to light is called a "fixed" dilated pupil. Dilated pupils aren't the same as anisocoria , a common condition where both pupils react normally to light but differ in size by about a half-millimeter or more.
The following prescription and non-prescription medicines can cause your pupils to dilate and affect their ability to react to light:. Atropine used for myopia control and other medical purposes. A serious, penetrating eye injury can damage your iris and cause the pupil to become dilated and irregular in shape. Sometimes, this sort of injury can occur during an eye surgery, such as a complicated cataract surgery or a corneal transplant.
A head injury , stroke or brain tumor can affect how your pupils react to light and cause dilated pupils. One or both eyes may be affected. This is why you see physicians checking an athlete's pupils with a penlight following head trauma sustained during sporting events, or when a patient arrives at a hospital emergency department with other possible stroke symptoms. Research has shown that alcohol and marijuana — separately or in combination — can reduce your eyes' ability to recover from exposure to a bright light source such as oncoming headlights at night and adapt to changing light conditions.
This effect can last two hours or longer after drug ingestion. A number of illegal drugs, however, do directly cause dilated pupils. This slows your eyes' ability to react to light. Glaucoma The optic nerve can be seen through an undilated pupil, but for optimum viewing a dilated pupil is required.
Macular Degeneration Two very common retinal diseases, diabetic retinopathy and age-related macular degeneration AMD , are diagnosed and monitored by examining the retina through a dilated pupil. Other Conditions In addition to macular degeneration and glaucoma, there are many other conditions that require pupil dilation, such as detection of a retinal tear or detachment, or an ocular tumor, just to name a few. The National Eye Institute generally recommends that starting at age 60 everyone should have an annual, comprehensive, dilated eye examination.
If you are African-American, the recommended age of having a dilated eye exam is 40 years old, because of the higher risk of glaucoma. The American Academy of Ophthalmology has specific recommendations for diabetic patients.
It is recommended that Type 1 diabetics have their first eye exam within five years of diagnosis. Type 2 diabetics, should have their eye exam at the time of diagnosis. If you are a diabetic woman considering pregnancy, it is recommended to have an exam prior to conception or early in the first trimester. Summary As part of a comprehensive eye examination, pupil dilation is very important at revealing the status of your optic nerve and retina, and is critical to preventing and treating eye conditions that could potentially lead to vision loss.
