Dry eye disease, also known as keratoconjunctivitis sicca and keratitis sicca, is a multifactorial disease of the tears and the ocular surface that results in discomfort, visual disturbance, and tear film instability. Dry eye disease is a common form of ocular surface disease and may overlap with other causes of ocular surface disease, such as ocular allergy and meibomian gland dysfunction.
Dry eye disease is very common in the United States, affecting a significant percentage of the population, especially those older than 40 years. Prevalence estimates range from approximately 10% to 30% of the population. An estimated 3.23 million women and 1.68 million men aged 50 years and older are affected. Early detection and treatment of dry eye disease may help prevent potential damage to the ocular surface as well as improve quality-of-life metrics. Treatment depends on the level of severity and may include medications, eye protection devices, and surgical interventions.
