A glass capillary tube (10 μL) purchased from Merck (Schnelldorf, Germany) was used to collect a tear sample (1 μL) from the lower meniscus of both eyes in each subject. The tear sample was dried at 23°C (humidity <40%) for 10 mins. WebThe lower tear meniscus status was evaluated using Fourier domain optical coherence tomography (FD-OCT). Vertical 2 mm scan images of the middle of the lower eyelid were obtained three times per eye. The tear meniscus height (TMH), tear meniscus depth (TMD), and tear meniscus area (TMA) were measured.
