Meibomian Glands or Not? Identification of In Vivo and Ex Vivo Confocal Microscopy Features and Histological Correlates in the Eyelid Margin

Figure 2

The cross-section of the dermoepidermal junction of the eyelid margin: (a) ex vivo confocal microscopy mode; (b) H&E stained histological section. In this part, the epidermis basement membrane surrounds the dermal papilla. In vivo confocal mode shows that the dermoepidermal junction is composed of a low-reflection area surrounded by a highly reflective layer. The dermal papilla of the skin part has a larger diameter, a higher density, and a polygonal shape (c). The conjunctival part has small diameter, low density, round shape (d). Flowing blood cells are visible in some of the dermal papilla: (e) In vivo confocal microscopy mode; the longitudinal section of H&E stained dermal papilla (scale bar: 50 μm). Arrowheads mark capillaries filled with blood cell.
