Tests and diagnosisBy Mayo Clinic staff
Tests and procedures used to determine the cause of your dry eyes may include:
- A comprehensive eye exam. An eye exam that includes a complete history of your overall health and your eye health can help your doctor diagnose the cause of your dry eyes.
- Measuring the volume of your tears. Your doctor may measure your tear production using the Schirmer test. In this test, blotting strips of paper are placed under your lower eyelids. After five minutes your doctor measures the amount of strip soaked by your tears.
- Determining the quality of your tears. Other tests use special dyes in eyedrops to determine the surface condition of your eyes. Your doctor looks for staining patterns on the corneas and measures how long it takes before your tears evaporate.
