Dilated Eye Exam: What Is It and When Is It Necessary?

A dilated eye exam involves increasing the size of the pupil so the specialist can better evaluate the condition of the optic nerve and retina. When dilated, your eyes will be more sensitive to light for a few hours, and it may not be safe for you to drive. This type of assessment is essential in detecting vision-threatening conditions.

What Is a Dilated Eye Exam?

Dilating eye drops widen your pupils, allowing more light and let your doctor see the back of your eye. It usually takes around 15 to 30 minutes for the pupils to dilate, depending on your response to the medication. It then takes around four to six hours for the pupils to return to their normal state after dilation. This type of eye exam allows specialists to diagnose conditions like glaucoma, retinal detachment, high blood pressure, diabetes and macular degeneration. 

Who Needs This Assessment?

According to the National Eye Institute, people who are 60 and older should undergo a comprehensive, dilated eye examination yearly. You should also see your eye doctor annually if you are of African-American heritage and at least 40 years old, due to a higher risk of glaucoma. 

If you have Type 1 diabetes, you should see your eye doctor for your first eye exam within five years of diagnosis. Type 2 diabetics should have their eyes checked at the time of diagnosis. Diabetics who are planning on getting pregnant should get an eye exam before conception or during the beginning of the first trimester.
