Comprehensive Eye Exam

In order maintain the health of your eyes; it is recommended to have them examined annually. Most insurances pay for an annual exam. A comprehensive eye exam may include, the following tests. Individual patient signs and symptoms, along with the professional judgment of Dr. Brown, may significantly influence the testing done.

Patient History

Your history helps us determine any symptoms you’re experiencing, when they began, the presence of any general health problems, medications taken and occupational or environmental conditions that may be affecting vision. We will ask about any eye or vision problems you may be having and about your overall health and that of your family members.

Visual Acuity

Reading charts are often used to measure visual acuity.
Visual acuity measurements evaluate how clearly each eye is seeing. As part of the testing, you are asked to read letters on distance and near reading charts. The results of visual acuity testing are written as a fraction such as 20/20.

When testing distance vision, the top number in the fraction is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read. A person with 20/40 visual acuity would have to get within 20 feet of a letter that should be seen at 40 feet in order to see it clearly. Normal distance visual acuity is 20/20.

Preliminary Tests

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.


Corneal Analysis

Not covered by most insurances and is used for determining refractive error. OPD Scan III® is unique and is the most advanced vision estimate system. It combines popography, wavefront, auto refraction, keratometry, pupillometry – allowing accurate and reliable analysis of corneal aberrations.

This testing may be done without the use of eye drops to determine how the eyes respond under normal seeing conditions. In some cases, such as for patients who can’t respond verbally or when some of the eyes focusing power may be hidden, eye drops are used. The drops temporarily keep the eyes from changing focus while testing is done and can last up to 12 hours.

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. In order 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

Tonometry measures eye pressure. Elevated pressure in the eye signals an increased risk for glaucoma. 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.

Supplemental Testing

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, Dr. Brown, will assess and evaluate the results of the testing to determine a diagnosis and develop a treatment plan. He will discuss with you the nature of any visual or eye health problems found and explain available treatment options. In some cases, referral for consultation with a retina specialist, or treatment by another health care provider may be indicated.

If you have questions regarding any eye or vision conditions diagnosed, or treatment recommended, don’t hesitate to ask for additional information or explanation from Dr. Brown.
