Brightfield microscopy of the eyelid. A. Rabbit eyelid showing very dark, acinar regions (arrow) indicating markedly decreased light transmission through the tissue section. Other areas showing increased light transmission compared to the acini were the central duct (asterisk), dermis (arrowhead) and orbicularis muscle (M). B. Note that the area adjacent to the acini in the region of disintegrating meibocytes releasing meibum into the short ductules (small arrows) showed increased transmission of light compared to the acini. C. Human eyelid showing similar loss of light transmission through the acini, and increased light transmission through the central duct (asterisk), tarsus (arrowhead) and orbicularis muscle (M).
