What is a comprehensive dilated eye exam?
Dilation: Drops are placed in your eyes to dilate, or widen, the pupils. Your eye care professional uses a special magnifying lens to examine your retina to look for signs of damage and other eye problems, such as diabetic retinopathy or age-related macular degeneration. This video helps describe what a doctor sees when examining the retina, optic nerve and macula after the pupils are dilated.
Dilation is the most important part of a comprehensive eye exam because it allows your eye care professional to get a better view of the inside of the eye.
Tonometry: This test helps to detect glaucoma by measuring eye pressure. Your eye care professional may direct a quick puff of air onto the eye, or gently apply a pressure-sensitive tip near or against the eye. Numbing drops may be applied to your eye for this test. Elevated pressure is a possible sign of glaucoma.
Visual field test: This test measures your side (peripheral) vision. It helps your eye care professional find out if you have lost side vision, a sign of glaucoma.
Visual acuity test: This eye chart test measures how well you see at various distances.
