What To Expect in a Checkup Eye Exam

Boy getting eye exam Hargrave Eye Center BlogAccording to WebMD, it’s important for adults 40 and older to have eye exams every 1 to 2 years to check for problems.  These regular eye exams are critical for finding things like:

  • Glaucomagroup of eye diseases causing optic nerve damage. 
  • Age-related macular degeneration:  common eye condition and a leading cause of vision loss among people age 50 and older.
  • Cataractsa clouding of the normally clear lens of your eye. 
  • Diabetic retinopathya diabetes complication that affects eyes.

This is particularly important if you have risk factors or a family history of eye problems.  At the start of the eye examination, your optometrist will ask why you are having your eyes examined, whether it is a routine check-up or if you have come for a specific reason.

If you are experiencing problems with your eyes or vision your optometrist will need to know what symptoms you have, how long you have had them and whether any changes have happened suddenly or slowly over a period of time.  Your optometrist will also need to know about your general health including any medication you are taking, whether you suffer from headaches, or have any close relatives with a history of eye problems.

You’ll likely have all or most of the following eye tests (you may also have more specialized eye tests), according to WebMD:

 To assure that the eyes are normally aligned, the doctor will ask you to visually track a target in different directions and observe your eye movements.

Cover test:

As you stare at a small target some distance away, the doctor will cover and uncover each eye to observe how much your eyes move, watching for an eye that turns away from the target (strabismus). The test may be repeated with a target close to you.

External exam and pupillary reactions:

Visual acuity test:

Eye Exam Hargrave Eye Center BlogThe eye doctor may shine a light in your eyes and flip lenses in a machine (phoropter) that you look through while staring at a large target, such as a big “E,” or the doctor may use an automated machine (refractor) for the same purpose. By checking the way light reflects from your eyes, the doctor gets an approximate idea of the lens prescription you need now.

Others Include:

  • Refraction testing: For your exact lens prescription, the eye doctor may use the results of the computerized refractor, or he or she may fine-tune the prescription manually by asking you to respond to questions such as, “Which is better, this or that?” while flipping back and forth between different lenses. If you don’t need corrective lenses, you won’t have this test.
  • Slit lamp: The slit lamp magnifies and lights up the front of your eye. The eye doctor uses it to detect several eye diseases and disorders by examining your cornea, iris, lens, and anterior chamber.
  • Retinal examination: Using an ophthalmoscope and pupil dilation, the eye doctor examines the back of your eyes: retina, retinal blood vessels, vitreous, and optic nerve head.
  • Glaucoma testing: This tests whether the fluid pressure inside your eyes is within a normal range. Painless and taking just a few seconds, the test can be done several ways.
  • Pachymetry: This test uses ultrasound to measure corneal thickness. Thin corneas can lead to falsely low pressure readings and thick corneas can lead to falsely high pressure readings. This test is done just once to create a baseline for future testing. Pachymetry may be needed if you are being considered for corneal surgery.
  • Pupil dilation (enlargement): With your pupils fully enlarged, the eye doctor will examine the inside of your eyes with different instruments and lights. The pupil-enlarging drops for this part of your eye exam start to work after about 20-30 minutes, making your eyes more sensitive to light and blurring your vision. These effects may last for several hours or longer so it’s important to bring a pair of sunglasses to your exam for the ride home.
  • Visual field test (perimetry): Your visual field is the area you can see in front of you without moving your eyes. Using one of three tests, the eye doctor “maps” what you see at the edges (periphery) of your visual field, using this map in diagnosing your eye condition.
