Image [3]: Muscles of the eyelid Muscles of the Eyelid Images [4, 5]: Dermatitis of the eyelid Reconstructive eyelid surgery
Subcutaneous tissue consists of loose connective tissue
Eyelid dermatitis is the inflammation of the eyelid skin Skin and Subcutaneous Tissue [3] Table [3]: Function of various anatomical features of the eyelid and eye Image [3]: Surface Anatomy of the left eyelid Surface Anatomy [3] Image [1]: Anatomy of the Eyelid Structure of upper and lower eyelids is similar, made of 4 layers:
Orbicularis muscle - layer of dense skeletal muscle
Tarsal plate - plate of dense fibroelastic tissue
Within layers are various types of glands:
Meibomian glands - sebaceous , secretes lipid-rich substance that delays evaporation of the tear film that lubricates and protects the cornea
Glands of Zeis - small sebaceous glands associated with eyelashes
Glands of Moll - apocrine sweat glands at the margin of the eyelid
Glands of Krause - accessory lacrimal glands in the fornix of the conjunctiva
Glands of Wolfring – accessory lacrimal glands just above the tarsal plate Overview of Anatomy [1] Anatomy – External Landmarks, Muscles, Innervation, Blood Supply and Lymphatics
