What is Osmolarity Testing?

Osmolarity testing is a diagnostic test for dry eyes. The osmolarity test measures the concentration of salt in the tears. A high concentration of salt is a good indication of disease activity and the presence of dry eye syndrome. A healthy individual will have a lower concentration of salt. At American Eye Associates, we offer osmolarity testing to better diagnose our patients and find the most appropriate treatment plans for them.

Do I need Osmolarity Testing?

We may recommend osmolarity testing for patients who are experiencing symptoms of dry eye syndrome. Similarly, if you are experiencing these symptoms, you may choose to pursue it yourself. These symptoms include:

  • Redness
  • Inflammation
  • Stinging or Burning
  • Excessive Tearing
  • Blurred Vision

How is the Osmolarity Testing performed?

The osmolarity test is performed using a simple handheld device. The device will be held up to the side of the eye to collect a tear sample, of which only a drop is needed. Once collected, the osmolarity device measures the concentration of salt in the tear sample based on its electrical conductivity. This analysis only takes a few moments, and it is entirely automatic. Within minutes, we will have the test results.

What are the expected results of Osmolarity Testing?

Osmolarity testing is measured in a unit known as milliosmoles per liter. The limits for varying eye dryness levels are as follows:

  • 316mOsmol/L and higher indicates dry eye syndrome.
  • 290mOsmol/L to 316mOsmol/L indicates borderline or intermittent dry eye
  • Less than 290mOsmol/L is a healthy or normal test result

What happens if I get a Dry Eye diagnosis?

The osmolarity test can accurately detect the presence of dry eye. Unfortunately, the test is limited as it cannot detect the cause of dry eye. If we measure dry eye conditions from your osmolarity test, we may recommend other diagnostic techniques based on your symptoms. In any case, we’re prepared to give you the treatment and professional advice you need when dealing with dry eye and its symptoms.
