Testing for Dry Eye is performed after evaluating a patient’s symptoms and medical history. A standard dry eye questionnaire may be used, providing a score for dry eye condition. The patient will answer based on their symptoms, such as persistent dryness, scratching, burning or a gritty sensation in the eye. In addition to evaluating symptoms, there are a number of simple tests that can be used to diagnose dry eye. These tests show how many tear the patient produces, how quickly tears evaporate, and if there is damage to the surface of the eye.
