Consensus was reached on treatment algorithms for DTS with and without concurrent lid disease. Clinical signs present in lids, tear film, conjunctiva, and cornea were also used for categorization of severity. Severity was assessed on the basis of tear substitute requirements, symptoms of ocular discomfort, and visual disturbance. Disease severity was considered the most important factor for treatment decision-making and was categorized into 4 levels. Development of algorithms was based on the presence or absence of lid margin disease and disturbances of tear distribution and clearance. Available diagnostic tests were considered of secondary importance in guiding therapy. Treatment recommendations were based primarily on patient symptoms and signs. Results: A new term for dry eye diseasewas proposed: dysfunctional tear syndrome (DTS). Treatment recommendations for different types and severity levels of dry eye disease were the main outcome. A two-thirds majority was used for consensus building from responses obtained. Based on available literature and standards of care, a survey was presented to each panelist. Methods: Of 25 preselected international specialists on dry eye, 17 agreed to participate in a modified, 2-round Delphi panel approach. These guidelines are not intended to override the clinical assessment and judgment of an expert clinician in individual cases, but they should prove helpful in the conduct of clinical practice and research.read more read lessĪbstract: Purpose: To develop current treatment recommendations for dry eye disease from consensus of expert advice. Finally, a scheme is presented, based on the severity of the dry eye disease, which is expected to provide a rational basis for therapy. It is stressed that any form of dry eye can interact with and exacerbate other forms of dry eye, as part of a vicious circle. The second is mechanistic and shows how each cause of dry eye may act through a common pathway. The first part is etiopathogenic and illustrates the multiple causes of dry eye. A new definition of dry eye was developed to reflect current understanding of the disease, and the committee recommended a three-part classification system. Abstract: The aim of the DEWS Definition and Classification Subcommittee was to provide a contemporary definition of dry eye disease, supported within a comprehensive classification framework.
