Retrospective nonrandomized observational study
Patients with epiphora or lacrimation were recruited at Ehime University. AS-OCT (CASIA SS-1000, Tomey, Japan) with customized software was used to record the tear meniscus at the center of the lower eyelid. Five microlitres of lukewarm saline solution was dropped into the lower conjunctival sac, and an image of the tear meniscus was obtained immediately and again 30 seconds after natural blinking. The tear meniscus height (TMH) and tear meniscus area (TMA) were measured in the AS-OCT images, and the percentage decrease in the TMH and TMA was used as a measure of the tear clearance.
