In each eyelid there are approximately 25-40 Meibom's glands in the upper eyelid and 20-30 in the lower eyelid, arranged vertically and parallel to each other, forming a characteristic pattern visible on transilluminating examination of the eyelids (meibography). These glands are holocrine glands, meaning that secretion occurs by the breakdown of whole lipid-filled epithelial cells, which accumulate in the central duct of the gland and are released onto the surface of the eyelid margin during blinking. Meibom's glands produce meibum, a complex mixture of lipids (mainly wax esters, cholesterol esters, triacylglycerols and free fatty acids) of an oil-like nature, which forms the outer, lipid layer of the tear film.<\/p>","protected":false},"featured_media":0,"parent":0,"template":"","meta":{"_acf_changed":false},"class_list":["post-4729","slownik","type-slownik","status-publish","hentry"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 - aioseo.com -->\n\t<meta name=\"description\" content=\"Gruczo\u0142y Meiboma to wyspecjalizowane gruczo\u0142y \u0142ojowe zlokalizowane w grubo\u015bci tarsusa (chrz\u0105stki) powiek g\u00f3rnych i dolnych, kt\u00f3rych uj\u015bcia otwieraj\u0105 si\u0119 wzd\u0142u\u017c tylnej kraw\u0119dzi brzegu powiekowego tu\u017c za lini\u0105 rz\u0119s.
