The eyes are your windows to the world. They can reveal your innermost feelings and emotions, your joy and happiness, your sorrow and sadness. Youth, beauty and wisdom may be fownd here also. To many, their sight is the most important of the senses yet to some, eyes are a continuous source of irritation and discomfort. Consequently, their eyes do not produce enough tears to be wet and comfortable as a result of a condition known as Dry Eye Syndrome.
The eponymic Schirmer tear test strip is currently supplied as a strip of 5 mm x 35 mm Whatman no. Schirmer Tear Tests are easy-to-read, calibrated test strips used to measure the volume of tear production in an animal. Low tear production can contribute to a number of eye problems. Strips are marked for left and right eye.
Methods and reagents for diagnosing Sjögren's Syndrome
The eye maintains a stable level of moisture and eliminates foreign particles by producing tears. This is a condition that occurs when the tear glands are unable to produce enough tears to keep the eyes moist. This causes stinging, burning, and redness in the eye. Blurred vision is another common symptom of dry eye syndrome.
The tear film, secreted by the lacrimal, Krause, and Wolfring glands, covers the surface of the eye. Blinking spreads tears over the eye and moves them toward an opening in the lower eyelid known as the punctum. Tears drain through the punctum into the nasolacrimal duct and into the nose. The Schirmer tear test simultaneously tests both eyes to assess lacrimal gland function by determining the amount of moisture accumulated on standardized filter paper or strips held against the conjunctival sac of each eye.
