Diagnosis

Diagnosis

of Dry Eye Disease and what to expect
in your appointment.

Only a doctor can determine if you have Dry Eye Disease.

At an Accredited Dry Eye Center, your doctor will ask a series of questions to determine your risk level for dry eye disease. In order to definitively diagnose your disease, the doctor may perform a TearLab® Osmolarity Test.

Often, dry eye symptoms are not dry eye at all.  The  TearLab® Osmolarity Test will help the doctor determine if this is your problem or if there is something else going on.

The TearLab® Osmolarity Test takes a tiny tear sample from each eye and generates your osmolarity number in seconds. Its quick, and painless, and gives your doctor a meaningful measure of the health and stability of your tear film.

What’s Your Number?

Tearlab Osmolarity Test Score

This number helps your doctor grade your dry eye as mild, moderate, or severe, and will enable the doctor to choose a treatment plan that works specifically for you and your dry eye condition. (Other tests may be performed in addition to the TearLab to help the doctor determine the underlying cause of the disease)

From the FDA website:

Why does your doctor use lab tests? Your doctor uses laboratory tests to help:

  • identify changes in your health condition before any symptoms occur
  • diagnose a disease or condition before you have symptoms
  • plan your treatment for a disease or condition,
  • evaluate your response to a treatment, or
  • monitor the course of a disease over time.

How are lab tests analyzed? After your doctor collects a sample from your body, it is sent to a laboratory. Laboratories perform tests on the sample to see if it reacts to different substances. Depending on the test, a reaction may mean you do have a particular condition or it may mean that you do not have the particular condition. Sometimes laboratories compare your results to results obtained from previous tests, to see if there has been a change in your condition.

What do lab tests show? Lab tests show whether or not your results fall within normal ranges. Normal test values are usually given as a range, rather than as a specific number, because normal values vary from person to person. What is normal for one person may not be normal for another person.

Some laboratory tests are precise, reliable indicators of specific health problems, while others provide more general information that gives doctors clues to your possible health problems. Information obtained from laboratory tests may help doctors decide whether other tests or procedures are needed to make a diagnosis or to develop or revise a previous treatment plan. All laboratory test results must be interpreted within the context of your overall health and should be used along with other exams or tests.
