Left Lacrimal Gland (Glandula lacrimalis sinister)
Educational content only — not medical advice.
Anatomy
The left lacrimal gland is a serous exocrine gland situated within the lacrimal fossa in the superolateral roof of the left orbit. Divided by the lateral horn of the levator palpebrae superioris aponeurosis into a larger orbital part and a smaller palpebral part, it secretes reflex tears containing lysozyme, lactoferrin, and secretory IgA to lubricate and protect the corneal surface.
Clinical notes
Dacryoadenitis is inflammation of the lacrimal gland producing an S-shaped ptosis of the upper eyelid; Sjögren syndrome causes autoimmune destruction with severe keratoconjunctivitis sicca.
