Diagnosis & Tests
How is the condition diagnosed?
A medical eye doctor can usually diagnose dry eye by examining the eyes. There are painless methods of measuring tear production. For example, a small paper strip can be placed over the lower eyelid for about 5 minutes to measure the eye's ability to make tears. Another test involves placing a drop of stain in the eye to look for a particular pattern of staining on the surface of the eye. A full history and physical exam, blood tests, and other tests may be done.
