Correct Answer: < 10mm with anesthetic
Schirmer’s Test is a test of tear production and is useful in diagnosis of dry eye syndrome. Normally, tear production should be at least 10-15mm after application of a topical anesthetic. Without anesthetic, increased tear production is expected to account for any foreign body sensation induced by the strips. In a patient with dry eyes, one would expect less than 10mm of tear production with anesthetic after 5 minutes.
