TESTING FOR DRY EYE
STEP 1-SCHIRMER TESTING
The Schirmer test is a standardized test which measures the aqueous (water) portion of the tear production. There are three Shirmer testing is not adequate to prescribe a successful remedy for dry eye on its own but is necessary as a part of the workup.portions our tears: water, mucous and oil. All three are important, and whether the watery portion is lacking is detected by this test.
STEP 2-SURFACE STAINS
Use of a high-resolution microscope and digital photography after applying various stains (fluorescein and lissamine green) in the form of drops allow us to evaluate the quality of the tear film and detect surface damage to the eye from dryness. Such testing also allows us to document and monitor improvements in dry eye and surface health over time.
The InflammaDry test detects the presence of the MMP-9 protein marker in the tear film. This is a substance which shows the presence of inflammation in the ocular tissues. Inflammation is not quieted by artificial tear drops alone and may be a reason that such products do not always help in the treatment of dry eye. Recognizing inflammation allows us to prescribe a proper treatment to relieve your dry eye symptoms.
STEP 4-TEAR LAB TESTING
The Tear Lab instrument measures tear osmolarity, a critical tear quality index which shows the tear film’s ability to resist premature evaporation. Information gathered from this test is used to properly choose the type of artificial tears that will be helpful. Results are also used to monitor the effectiveness of treatment over time. This is essentially a measurement of how “normal and balanced” the tears are and allows the doctor to supplement what is lacking.
Lipiscan is an imaging device that reveals the function of the glands of the eyelid margin. Congested or blocked glands are revealed and the degree to which gland dysfunction contributes to eyelid inflammation is determined.
Lipiscan guides the physician and patient to decide whether the treatment of eyelid margin gland blockage is appropriate. If treatment is needed, the Lipiflow device described in the treatment section of our website is used.
