The lacrimal gland consists of secretory vesicles that secrete tears and a duct that drains them, and is located in the lacrimal fossa in the frontal bone above the outer orbit. The lacrimal gland is closely adherent to the orbital periosteum superiorly, adjacent to the orbital fat posteriorly, adjacent to the eyeball inferiorly, and rests on the levator ani muscle at its medial end; the lacrimal gland is anchored to the orbital periosteum by a connective tissue through which the tendon membrane of the levator ani muscle passes posterolaterally, dividing the lacrimal gland into a larger orbital lacrimal gland and a smaller blepharoplacental lacrimal gland. Lacrimal glands are exocrine glands that produce plasma both tears that drain through the excretory ducts into the conjunctival sac, lubricating and protecting the eye. Common causes of lacrimal gland diseases are inflammation, tumor, trauma, etc. Due to aging, trauma, various lesions or inflammation of the lacrimal gland can lead to atrophy of the lacrimal gland, resulting in patients with dry eyes and other discomforts. Patients with abnormal lacrimal glands are advised to seek timely hospital consultation to assess their condition and follow the doctor’s instructions for treatment.
