Tear flow ophthalmic strips, including Schirmer Tear Test Strips, accurately measure tear production to determine if the eye produces sufficient moisture. Commonly used for diagnosing dry eye and conditions like Sjgrens Syndrome, these strips are essential for comprehensive ocular assessments.
The primary difference lies in the measurement markings:
Tear Flow Test Strips (PO-5400) include a printed metric scale directly on each strip, allowing for quick, unmistakable interpretation without additional tools
Schirmer Tear Test Strips (PO-6394) do not include printed measurements, so a separate metric ruler is required during testing
Both types are used to assess tear production, but the printed metric scale on the Amcon version may assist clinical efficiency.
