Dilated Eye ExamsYour eye doctor in Conway wants you to know that dilated eye exams are important to your good vision. Healthy vision requires more than just a quick check with the eye chart – you need regular comprehensive dilated eye exams that give your optometrist a close-up view of the inside of your eyes.

Key elements of a comprehensive dilated eye exam include:

  • Dilation
  • Tonometry
  • Visual field test
  • Visual acuity test

During dilation, your optometrist will administer eye drops to enlarge your pupils. Tonometry uses a puff of air to help your optometrist detect elevated eye pressure associated with glaucoma. A visual acuity test measures how well you see at various distances, while a visual field tests measures your peripheral vision.

Eye Doctor in Conway Discusses the Importance of Dilated Eye Exams

Your eye doctor in Conway would like you to know that dilated eye exams are important because they help your optometrist see details inside the tissues of your eyes that might otherwise be difficult to see.

Dilation widens your pupil, which is the opening of the colored part of your eye known as the iris. Dilation helps your eye doctor in Conway view the inside of your eye by allowing more light to enter your eye, somewhat like opening the shade allows more light into a dark room.

After dilation, your eye doctor in Conway will use a special magnifying lens to look at the important tissues at the back of your eye, such as your retina, macula, and optic nerve. The retina is a light-sensitive layer of tissue lining the inner surface of your eye that acts like film in a camera. Your macula, an oval-shaped patch near the center of your retina, gives you forward vision that enables you to see straight ahead. Your optic nerve sends messages about what your retina and macula see to your brain for processing.

Your optometrist uses dilated eye exams to detect a variety of eye problems, including diabetic retinopathy, age-related macular degeneration (AMD), and glaucoma. Diabetic retinopathy is the most common diabetic eye disease, according to the National Eye Institute, and a leading cause of blindness in the United States. Dilated eye exams help your optometrist look for swollen or leaking blood vessels in the retina, a sign of diabetic neuropathy. These exams also help your eye doctor in Conway see yellow deposits in the retina, which are associated with AMD, a common cause of vision loss and blindness in people over the age of 50. Dilated eye exams also help your optometrist look for changes in the shape and color of the optic nerve fibers that would indicate the presence of glaucoma.

The primary side effects of dilated eye exams are light sensitivity and blurry vision, especially for near tasks. Sunglasses may be helpful. Dilation lasts for up to 24 hours.
