Description

The Schirmer Tear Test is used to measure the rate of tear production. It should be used to evaluate and diagnose tear deficiency as a contributing factor to diseases that occur on the surface of the eye including: Keratoconjunctivitis sicca (KCS), pigmentary keratitis, corneal ulcers, exposure keratitis, and others. It can also be used to evaluate tear duct function prior to eye surgery. This test comes as easy-to-read calibrated strips marked for left and right eyes.

Key Benefits
  • Each calibrated strip is easy to read.
  • Marked for both left and right eyes.
  • The blue dye wicks up the scale, creating better visibility when measuring your pet's tear production.
  • Designed with a color bar tear front indicator and a millimeter scale on the strip.

Instructions

The Schirmer Tear Test is comprised of a paper strip that is folded and hooked over the lower eyelid. Once in place, the tears begin to "wick" up the filter paper. The distance, in millimeters, that the tears wick up the test strip in one minute, represents th millimeters of tear production. Although Keratoconjunctivitis sicca (KCS) is bilateral, each eye may be at a different stage in the disease process at the time of examination. Therefore, if one eye tests abnormal, the other eye should also be treated or monitored closely.

    I was glad this was available and arrived quickly so I could check my dog's tear production while waiting for an appointment with the vet.
