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

Figure 3

Appendages and subcutis. In vivo confocal microscopy mode can only observe superficial hair follicles (a) and parts of glands of Zeis (b) opens into the hair follicle. The follicles, gland of Zeis ((c) ex vivo confocal microscopy mode; (d) H&E stained section), and eccrine gland ((e) ex vivo confocal microscopy mode; (f) H&E stained section) can be observed on the superficial layer of the skin, the gland of Moll ((g) ex vivo confocal microscopy mode; (h) H&E stained section) can be observed in the deep layer. The meibomian gland ((i) ex vivo confocal microscopy mode; (j) H&E stained section) can be observed in the deep layer of the conjunctiva (scale bar: 50 μm).
