Diagnosing Dry Eye

Diagnosis of Dry Eye is quick and simple – the test only takes 60 seconds. Your veterinarian probably already tests most dogs with eye problems as well as predisposed breeds routinely.

Your veterinarian measures tear production in dogs using a Schirmer tear test (STT). The STT involves placing a special strip of paper in the eye to assess tear production. Usually the tear production in both eyes is tested as the results are often quite different. The test will not cause your dog any discomfort and does not require sedation or anesthesia. The results of this test are available are immediately. The results of the test are interpreted along with other findings, such as clinical signs, to determine whether KCS is present. If your dog has Dry Eye, it is not producing sufficient tears and should be started on treatment immediately.
