Schirmer's test
From WikiLectures
The Schirmer test is used to assess the amount of tear production . Special strips of filter paper (5 × 35 mm, 5 mm folded from the end) are inserted into the lower conjunctival sac of both eyes (at the interface of the outer and middle third). After 5 minutes, we evaluate the length of the wet section, with normal reflex formation of the aqueous component of tears, it should be longer than 10 mm . It is mainly used in the diagnosis of dry eye syndrome .
Test Variants:
- Schirmer's test Even without anesthetic - measures both basal and reflex secretion
- Schirmer's test I with anesthetic - measures only basal secretion, tells about the activity of accessory glands (dysfunction in inflammation , eg in sarcoidosis , Sjörgen's syndrome )
- Schirmer's test II with anesthetic - measures the reflex secretion of tears when irritating the nasal mucosa
