    Current opinion in ophthalmology·1996

    Lysozyme concentrations in reflex-stimulated tears and anesthetized tears showed no significant statistical difference. This suggests a common or similarly regulated source for both tear types.

    Area of Science:

    • Ophthalmology
    • Biochemistry

    Background:

    • Tear film composition is crucial for ocular surface health.
    • Lysozyme is a key protein component of the tear film.

    Purpose of the Study:

    • To compare lysozyme concentrations in reflex-stimulated tears versus tears collected after local anesthesia.
    • To investigate potential differences in tear secretion sources based on lysozyme levels.

    Main Methods:

    • Tear fluid was collected from subjects under reflex stimulation and after local anesthesia.
    • Lysozyme concentration (microgram/ml HEL) was measured and statistically compared between the two conditions.
    • Data were corrected for volume differences and matched against standard concentrations.

    Main Results:

    Related Experiment Videos

    • No statistically significant difference was found in lysozyme concentration between reflex-stimulated tears and anesthetized tears.
    • This indicates consistent lysozyme levels regardless of the stimulation method.

    Conclusions:

    • The findings suggest a common origin for both stimulated and unstimulated tears.
    • Alternatively, distinct tear sources may secrete tears with identical lysozyme concentrations.
