Schirmer Tear Test, 5 Sets The Schirmer Tear Test is a diagnostic tool used to measure the rate of tear production in the eyes. It is essential for evaluating conjunctivitis and diagnosing tear deficiency as a contributing factor to ocular surface diseases. Additionally, it is used to assess lacrimal gland function prior to cataract surgery. Measures tear production rates for accurate diagnosis. Assists in evaluating conjunctivitis and other ocular surface diseases. Helps assess lacrimal gland function before cataract surgery. Utilizes standardized sterile 5x35mm strips for reliable results. Immediate evaluation is crucial for accurate measurement. DIRECTIONS: The Schirmer Tear Test should be performed prior to the installation of any topical medication or manipulation of the eyelids. It is not necessary to use topical anesthesia for this test. Avoid touching the ocular end of the strip with your fingers. If there is copious discharge present on the surface of the eye, it may be removed with a gauze sponge before performing the test, but this step is not mandatory. To perform the test, hook the rounded notched end of the sterile strip over the juncture of the temporal and middle thirds of the lower lid margin. Note the time. The eyelids can be held shut, or the patient can be allowed to keep its eyes open and blink freely while the strip dries. After 60 seconds, remove the strip and immediately measure the length of the moistened area. Visualization of the wetting length is aided by blue dye that advances with the tear front. A millimeter scale is printed on each strip for accurate measurement. CAUTIONS/WARNINGS: The Schirmer Tear Tests are intended for single patient use only. Contents are sterile if the package is unopened and undamaged. Do not use if the package has been previously opened.
