Overview of

Pupil Dilation

in Thailand

Pupil dilation involves the use of eye drops to widen your pupils, allowing in more light and giving the doctor a better view of the back of your eye, including the blood vessels. Eye dilation may be done as part of a comprehensive eye examination or to look for an acute injury, such as a retinal detachment. No matter the reason for the dilation, it is performed in the same manner. The doctor will input eye drops that work to widen your pupils. How often you need to have your pupils dilated will depend on several factors. For those with relatively good overall health, your doctor may only recommend it when you have routine eye examinations. The following may impact the schedule your doctor recommends: -You are over 60 years old. -You have a history of retinal detachment or other eye issues that affect the structures at the back of your eye. -You are experiencing new eye symptoms. -You are Hispanic or African American, which means you have an increased glaucoma risk. -You have diabetes or other health issues that can affect your eye health.

Preparation before

Pupil Dilation

Pre - treatment

Since the procedure allows more light into your eye, natural, normal light will seem much brighter to you, causing your eyes to tear. It is important that you have a family member or friend accompany you if you know you will be undergoing pupil dilation as you will not be able to see well.

Recovery after

Pupil Dilation

Post - treatment

Because of the excessive light that will enter your eye, it is not recommended that you drive until the medication’s effects have worn off.

Risks & side effects

You will find it difficult to see things that are close to you. This is temporary and should resolve on its own within four to six hours or so. If you experience worsening blurry vision, see rainbows around lights, have severe eye pain and/or heaviness, and feel nauseated or vomit, please let your doctor

FAQs:

Pupil Dilation

How long does dilation last?

The average dilation is four to six hours. The exact eye drops the doctor uses impact how long your eyes remain dilated.

Commonly used eye drops include:

-Phenylephrine

-Hydroxyamphetamine

-Atropine

-Tropicamide

-Cyclopentolate

The doctor usually inputs two types of drops into your eyes to dilate your pupils. One of the drops used causes the muscles that control the pupil to contract so the pupil becomes larger. Phenylephrine is an example of this type of eye drop. The second type that is used relaxes the muscle that is responsible for the eye lens focusing. It also relaxes the muscles that allow the pupil to become smaller. Cyclopentolate is an example of this type of eye drop. If you are having eye dilation performed for the first time, you should plan to experience dilation for at least six hours. Consider getting a ride home from the doctor, and make sure you have sunglasses to reduce the light sensitivity that is common when your pupils are dilated.

‍

Can I reduce dilated eyes faster?

There is no way to reduce your pupil size faster. You might consider taking a nap once you get home to reduce how much light your eyes are exposed to. Since it can be hard to do things like read or see a television screen if your vision is blurry, it is best to avoid these activities until the effects wear off.
