Dilated Eye Exam: Everything You Need to Know
Introducing the dilated eye exam – what it is and why it’s important
A dilated eye exam is an important part of a comprehensive eye exam. During a dilated eye exam, is an examination of the inside of your eyes to check for any sign of disease. The exam is important because it allows your doctor to see the health of your retina, the nerve tissue that lines the back of your eye, and the macula, the small area of the retina that provides sharp, central vision.
During a dilated eye exam, your eye care professional places drops in your eyes to widen, or dilate, the pupils. This dilation enables your eye care professional to see inside your eyes more easily and to look for early signs of disease.

Dilated eye exams can help diagnose many different eye problems, including:
• Age-related macular degeneration

After your pupils have dilated, your doctor will use a special magnifying lens to look at your retina and the back of your eye.
He or she will also check your eye pressure and look for any signs of damage to your optic nerve. The dilated eye exam is the best way to detect many eye diseases, such as glaucoma, early. It is important to have a dilated eye exam at least once a year, especially if you are over the age of 60 or have a family history of glaucoma.
