Discussing your symptoms and medical history can help your doctor determine which tests are most likely to provide information on your condition.
Tear Drainage Tests
Your doctor can use a special saline solution to gauge the drainage rate of your tear ducts. In some cases, x-rays may be necessary to reveal an obstruction.
Your doctor may perform one or several tests to determine the cause of excess tearing.
Testing for Dry Eye, Allergies, Conjunctivitis, Etc.
Your doctor may conduct any number of tests to determine if an illness is causing your excessive tearing. This can involve a visual exam, or a test of your tear quality (which is often compromised in those suffering from dry eye syndrome). In some cases, your doctor may recommend a fluorescein stain, which involves placing dye on the surface of the eye to reveal any foreign objects. The doctor will also look for any corneal scratches or abrasions.
