What Is Lacrimal Insufficiency?
Lacrimal insufficiency is decreased aqueous tear production by the main and accessory lacrimal glands, leading to an unstable tear film and dry eye symptoms. With fewer tears, the ocular surface dries out, becomes inflamed, and loses its smooth optical quality. Patients experience burning, grittiness, and fluctuating vision that worsen with reading or screen use. Causes include aging, autoimmune disease, and damage to the lacrimal glands. If severe, the condition can produce persistent keratoconjunctivitis sicca and surface damage.
