Tear Test Strip Suppliers and Manufacturers

Tear Test Strips, specifically those of the Schirmer type, are diagnostic tools commonly used in ophthalmology to measure tear production. Here's more information about Tear Test Strips of the Schirmer type: Purpose: Tear Test Strips (Schirmer) are primarily used to assess the quantity of tears produced by the lacrimal glands. This test helps diagnose conditions such as dry eye syndrome, also known as keratoconjunctivitis sicca, by evaluating tear production levels. Design: Schirmer Tear Test Strips are thin, paper-like strips that are usually marked with millimeter (mm) gradations. The strips are typically designed to be inserted into the lower eyelid's conjunctival sac, where they absorb tears over a specified period. Packaging: Tear Test Strips (Schirmer) are commonly packaged in individual packets or vials to maintain sterility and prevent contamination. A pack of 100 Tear Test Strips would contain 100 individual strips, each sealed in its own packet. Usage: To perform the Schirmer Tear Test, a single strip is inserted into the lower eyelid's conjunctival sac, usually at the outer corner of the eye. The patient is instructed to keep their eyes closed during the test, which typically lasts for a few minutes. After the specified time, the strips are removed and the amount of tear wetting is measured using the mm gradations on the strip. Interpretation: The length of tear wetting on the Tear Test Strip (Schirmer) provides an indication of the quantity of tears produced by the lacrimal glands. Reduced tear wetting may indicate decreased tear production, which can be indicative of dry eye syndrome or other ocular surface disorders. Variations: There are variations of the Schirmer Tear Test, including the Schirmer I test (without anesthesia) and the Schirmer II test (with anesthesia). The Schirmer I test measures basal tear secretion, while the Schirmer II test evaluates reflex tear secretion after instillation of anesthetic eye drops. Safety and Precautions: Tear Test Strips (Schirmer) should be handled and disposed of according to standard precautions for ocular diagnostic procedures. Care should be taken to avoid contamination and ensure accurate test results.

Tear Test Strips, commonly used in ophthalmology, are diagnostic tools to assess tear production and the health of the ocular surface. Here's more information about Tear Test Strips with Rose Bengal dye: Purpose: Tear Test Strips with Rose Bengal dye are primarily used to evaluate tear production and diagnose conditions such as dry eye syndrome, keratoconjunctivitis sicca, and other ocular surface disorders. Rose Bengal dye stains areas of the ocular surface where there is damage or insufficient tear film, aiding in the diagnosis of these conditions. Composition: Tear Test Strips with Rose Bengal dye are thin, paper-like strips impregnated with Rose Bengal dye. Rose Bengal is a water-soluble stain that binds to damaged or devitalized cells on the ocular surface, highlighting areas of dryness, inflammation, or epithelial defects. Packaging: Tear Test Strips are typically packaged in individual packets or vials to maintain sterility and prevent contamination. A pack of 100 Tear Test Strips would contain 100 individual strips, each sealed in its own packet. Color: Tear Test Strips with Rose Bengal dye often have a distinctive pink or red color due to the presence of the dye. This coloration facilitates visualization and interpretation of the staining patterns on the ocular surface. Usage: To perform a Tear Test, a single strip is moistened with a sterile saline solution or artificial tears and then gently applied to the lower eyelid margin of the patient's eye. After a specified time, usually around 15-30 seconds, the strip is removed, and the staining pattern on the ocular surface is evaluated under a slit lamp or other magnification device. Interpretation: Areas of the ocular surface that are stained with Rose Bengal dye indicate regions of compromised epithelial integrity, reduced tear film stability, or inflammation. The severity and extent of staining can provide valuable information about the underlying pathology and guide treatment decisions. Safety and Precautions: Tear Test Strips with Rose Bengal dye should be handled and disposed of according to standard precautions for ocular diagnostic procedures. Care should be taken to avoid contact with the patient's skin and mucous membranes, and any unused strips should be discarded after use.
