Schir·mer test

(shir'mĕr),
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 test

A 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).

The most widely used diagnostic tests for tear film examination are tear break-up time (TBUT) test, corneal and conjunctival staining with fluorescein, rose bengal and lissamine green dye, Schirmer test, tear film osmolarity test and impression cytology.

After examination for objective evidence of sicca complex by Schirmer test, TBUT and Ocular Staining Score (OSS), serological tests were performed.
A total of sixty patients with dry eye were recruited from among the outpatients in the Xiamen Eye Center of Xiamen University for this clinical study based on the following diagnostic criteria of aqueous tear deficiency: (1) presence of symptoms of dry eye; (2) abnormality of the tear production as determined by the Schirmer test (<5 mm after 5 min); (3) presence of tear film instability (<5 s); and (4) positive ocular surface Rose Bengal and fluorescein vital staining.
At the end of study none of the patients had Schirmer test <3 mm and more than 30 patients had Schirmer test with in normal range.
If you suspect your pet has "Dry Eye", make an appointment with your vet for a Schirmer test.
The Schirmer test, which is specific to SS, involves staining the cornea and measuring tear production.
4] Patients often complain of dry eye symptoms and in Schirmer test, decreasing of tear production is observed.
Decreased tearing may be measured by a Schirmer test I.
