Eye Health Exam
Protect your vision with regular eye exams for early signs of eye diseases such as glaucoma, cataracts and macular degeneration. Many eye diseases do not display early symptoms that you can detect on your own.
A comprehensive adult eye health exam may include, but is not limited to, the following tests. Individual patient signs and symptoms, along with the professional judgment of your eye doctor, may significantly influence the testing done.
A patient history helps to determine any symptoms you are experiencing, when they began, the presence of any general health problems, medications taken and occupational or environmental conditions that may be affecting vision. Your eye doctor will ask about any eye or vision problems you may be having and about your overall health. The doctor will also ask about any previous eye or health conditions of you and your family members.
Preliminary testing may include evaluation of specific aspects of visual function and eye health such as depth perception, color vision, eye muscle movements, peripheral or side vision and the way your pupils respond to light.
This test measures the curvature of the cornea, the clear outer surface of the eye, by focusing a circle of light on the cornea and measuring its reflection. This measurement is particularly critical in determining the proper fit for contact lenses.
Eye Focusing, Eye Teaming and Eye Movement Testing
Assessment of accommodation, ocular motility and binocular vision determines how well the eyes focus, move and work together. To obtain a clear, single image of what is being viewed, the eyes must effectively change focus, move and work in unison. This testing will look for problems that keep your eyes from focusing effectively or make using both eyes together difficult.
Eye Health Evaluation
Part of a comprehensive eye exam is the eye health evaluation. If you are at high risk for any eye disease, the health evaluation will assess the health of your eyes and can compare it to previous records to make sure that any changes in the results over time are observed and treated if necessary. Your optometrist will advise you during your exam if he or she feels additional testing is indicated, based on your diagnosis.
External examination of the eye includes evaluation of the cornea, eyelids, conjunctiva and surrounding eye tissue using bright light and magnification. Evaluation of the lens, retina and posterior section of the eye may be done through a dilated pupil to provide a better view of the internal structures of the eye.
Measurement of pressure within the eye (tonometry) is also performed. Normal eye pressures range from 10 to 21 millimeters of mercury (mm Hg), averaging about 14 to 16 mm Hg. Anyone with eye pressure greater than 22 mm Hg is at an increased risk of developing glaucoma, although many people with normal pressure also develop glaucoma.
Additional testing may be needed based on the results of the previous tests to confirm or rule out possible problems, to clarify uncertain findings or to provide a more in-depth assessment.
At the completion of the examination, your optometrist will assess and evaluate the results of the testing to determine a diagnosis and develop a treatment plan. He or she will discuss with you the nature of any eye health problems found and explain available treatment options. In some cases, referral for consultation with or treatment by other health care providers may be indicated.
Besides an annual eye health exam, you also need a yearly vision eye test.
This was my first visit to Dr. McDougal’s office. I found the office personnel very friendly as well as helpful and polite. Dr. McDougal has a warm and friendly personality. I felt at ease with him and although I had no questions for him, he allowed time for any I might have. As a diabetic I left the office with the assurance that my eyes are healthy. I would recommend Dr. McDougal to anyone who might ask. — Pamela W.
