Emerging developments in dry eye
August 1, 2017 - Rod McNeil on Eye News
An estimated 344 million people worldwide suffer from dry eye [1]. This chronic syndrome is characterised by a vicious cycle of tear film hyperosmolarity, tear instability and corneal stress, leading to increased friction, inflammation, ocular surface damage and decreased visual acuity. The author reviews emerging developments focused on improving treatment success.
The Tear Film & Ocular Surface Society (TFOS) Dry Eye Workshop II (DEWS II) global consensus report represents the first evidence-based reexamination of multiple aspects of dry eye disease (DED) since the initial international seminal DEWS report issued in 2007. TFOS DEWS II sought over the past two years to update the definition, classification and diagnosis of DED, critically evaluate the epidemiology, pathophysiology, mechanism, and impact of this disorder, address its management and therapy and develop recommendations for the design of clinical trials to assess pharmaceutical interventions for DED treatment.
DEWS II has redefined dry eye as a multifactorial disease of the ocular surface characterised 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 aetiological roles.
