SCHIRMER's TEST ...
Schirmer's test determines whether the eye produces enough tears to keep it moist.
Schirmer's test uses paper strips inserted into the eye for several minutes to measure the production of tears. Both eyes are tested at the same time. Most often, this test consists of placing a small strip of filter paper inside the lower eyelid (conjunctival sac). The eyes are closed for 5 minutes. The paper is then removed and the amount of moisture is measured. This technique measures basic tear function. |
