A technique for visualizing tear meniscus in patients with lower eyelid sagging or retraction.

摘要

Tear meniscus height measurement is one of the key examinations for evaluating dry eyes. Although it is easy to determine the tear meniscus height in patients with normal lower eyelid position (higher than the lower corneal limbus), patients with lower eyelid sagging or retraction (lower than lower corneal limbus) show unclear tear meniscus (Fig. A). Fluorescein dye staining is helpful for this determination,2 but mis procedure is somewhat time-consuming and uses too much of clinician's time in busy outpatient sessions. We push the lower eyelid upward in such a situation, surpassing the lower corneal limbus to clearly visualize the tear meniscus (Fig. B).
