The primary components of the lacrimal apparatus, which include: The lacrimal gland and the accessory lacrimal gland . The lacrimal puncta , canaliculi , lacrimal sac and the nasolacrimal duct. Let us talk about each of these components one by one. The lacrimal gland lies in the superolateral aspect of the orbit. It is part of the lacrimal apparatus and is responsible for tear production . The lacrimal gland (tear gland) is an exocrine gland located above the eyeball , in the anterior part of the upper outer aspect of each orbit. It secretes lacrimal fluid (tear fluid), a watery fluid isotonic to plasma, onto the surface of the eyeball. The lacrimal gland is defined as a paired almond-shaped gland located in the upper lateral orbital region, responsible for approximately 90% of tear production and composed of an orbital and a palpebral lobe. It produces lacrimal fluid that lubricates, protects, and nourishes the conjunctiva and cornea. AI generated definition based on: Best Practice & Research Clinical Rheumatology, 2023
