![]() Testing should be performed in order from least to most invasive to minimize a test’s effect on subsequent results: ![]() 1 Clinicians should test for these key homeostasis markers in symptomatic patients using a positive screening questionnaire such as DEQ-5 (with a score >6) or OSDI (with a score >13). These are minimally invasive, clinically applicable and maintain high objectivity. While there may be a predominant cause, concurrent contributing factors are also possible.ĭEWS II recommends using three tests and techniques to identify and subtype DED. The new understanding of DED as a disruption of homeostasis on a spectrum of ocular surface dysfunction means identifying the factors contributing to a patient’s profile is key. Patient questionnaires such as the Dry Eye Questionnaire-5 (DEQ-5) or the Ocular Surface Disease Index (OSDI) are important tools when DED is suspected, as they can often differentiate DED from other conditions that may mimic its symptoms. The DEWS II Diagnostic Methodology subcommittee’s algorithm begins with the assessment of symptoms. Lissamine green staining of the lid margin shows >2mm of stain, which would qualify as a positive sign of lid wiper epitheliopathy, a key diagnostic criteria for dry eye disease. The expanded definition creates a spectrum of DED rather than a single process, sign or symptom that affects the entire ocular surface, including the tear film, cornea, conjunctiva, eyelids and lacrimal and meibomian glands. This expansive definition provides a more inclusive way to view a patient’s presenting signs and symptoms. As a result, the updated definition allows for a more comprehensive representation of DED, defining it 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.” 2 1 However, many practitioners have noted that patients can exhibit features of both subtypes. Previously, DED was seen either as evaporative-as a result of deficient lipid layer from meibomian gland dysfunction (MGD)-or aqueous deficient (reduced tear volume). One of the major developments of the DEWS II was the Definition and Classification subcommittee’s revamping of the description of dry eye. For the optometrist looking to better incorporate the findings of DEWS II into their practice, this article boils down the report’s lengthy discussion into actionable recommendations. I n 2017, the Tear Film & Ocular Surface Society updated the Dry Eye Workshop (DEWS II) to reflect a decade’s worth of advances in our understanding, diagnosis, treatment and management of dry eye disease (DED).
