(A) Representative output images of the noninvasive tear film break-up points and tear break-up time measurement from a non-Sjögren’s Syndrome Dry Eye (a) and a Sjögren’s Syndrome Dry Eye (b). The colored tear map showed the position of tear break-up point and the break-up time. Red: 0–6 s; orange/yellow: 6–12 s; green: 12–24 s. (B) Representative output images of meibography from a non-Sjögren’s Syndrome Dry Eye (a) and a Sjögren’s Syndrome Dry Eye (b). The meibomian gland dropout was more severe in Sjögren’s Syndrome Dry Eye (b) than non-Sjögren’s Syndrome Dry Eye (a). (C) The cornea surface was divided into five areas when observing cornea fluorescein staining
