a test for tear production using a strip of filter paper; a measurement of basal and reflex lacrimal gland function.
[Rudolph Schirmer, Ger. ophthalmologist, 1831–1896]
The use of an absorbent paper placed in the conjunctival sac as a test for patients with ocular irritation and dry eye, e.g., keratoconjunctivitis sicca. The rate and amount of wetting of the paper provide an estimate of tear production.
Schirmer testA test of tear production and the adequacy of corneal wetting in conditions such as SJOGREN'S SYNDROME. A narrow strip of filter paper is bent and hooked over the lower lid with one end between the lid and the eyeball. After a few minutes, wetting should extend for at least 8 mm. (Rudolph Schirmer, 1831–96, German ophthalmologist).
