About Chronic Dry Eye Disease
Dry eye disease is a common condition with a global prevalence between 5% and 34% and totaling more than an estimated 16 million Americans.6,7 It is a chronic inflammatory disease that can be initiated by numerous extrinsic or intrinsic factors that lead to an unstable and hyperosmolar tear film.8,9 Known risk factors include aging, female gender, refractive surgery and autoimmune disease.9 According to the International Dry Eye Workshop, dry eye disease is defined as “a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and hyperosmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles.”8 A primary mechanism responsible for dry eye is tear hyperosmolarity leading to tissue damage.8 Eye pain is caused by tear hyperosmolarity and loss of lubrication.8 Visual changes are due to tear and ocular surface abnormalities.8 Depending on severity, dry eye disease can limit daily activities such as using a computer, reading, driving and also adversely affect sleep and work productivity.10-12
