The examination should begin with a visual acuity recording. A Snellen chart at 20 feet should be available in most offices, but a near vision card can be used. For young children, an eye chart using pictures can be used. Patients who wear eyeglasses or contact lenses should wear them for testing if possible. Remember that a patient over 40 years of age with good distance vision probably still needs reading glasses for near vision. A red eye with decreased vision could signal a vision-threatening disorder. In general, red eyes with no vision loss can usually be treated by family physicians, but red eyes with any vision compromise should be referred where possible to an ophthalmologist.
