Schirmer's Tear Test

Evaluating Ocular Surface Health

Schirmer's Tear Test is an essential diagnostic tool used in optometry to assess tear production and evaluate ocular surface health. This simple yet effective test measures the volume of tear production over a specified time, providing critical insights into the function of the lacrimal gland. Adequate tear production is vital for maintaining the integrity of the ocular surface, ensuring lubrication, and protecting the eye from environmental irritants and pathogens. Low results on Schirmer's test may indicate dry eye syndrome or other conditions affecting tear secretion, guiding optometrists in recommending appropriate treatments such as artificial tears, punctal plugs, or lifestyle modifications.
