Dry eye is a multifactorial, progressive, and chronic disease of the tears and ocular surface. The disease is multi-factorial and has intermittent symptoms. Discomfort, visual disturbance, tear film instability with potential damage to the ocular surface, and increased tear film osmolarity are known associates. Dry eye is a common clinical problem for eye-care providers worldwide and there is a...

PurposeTo evaluate patterns and opinion from international experts with respect to dry eye disease (DED) diagnosis in clinical practice.MethodsAn online survey was distributed worldwide DED experts. The use of tests evaluated including: symptoms questionnaires, functional tests, tear stability, volume, composition, surface damage inflammation, eyelid assessment. After the subjective importance ...

PURPOSE To assess the diagnostic performance of a novel, automated, noninvasive measure of tear film stability derived from Placido disc videokeratography, the tear film surface quality breakup time (TFSQ-BUT), as a clinical marker for diagnosing dry eye disease (DED) relative to a standard of tear hyperosmolarity. METHODS This prospective, cross-sectional study involved 45 participants (28 D...

Artificial tear preparations are important in the management of dry eye syndrome. We present the findings from four recently published studies conducted in Russia assessing Hylabak(®) (marketed as Hyabak(®) in Europe), a preservative-free hyaluronic acid preparation, for the treatment of dry eye syndrome. All studies had an open, noncomparative design, but one compared the findings with those f...

The analysis of tear constituents at point-of-care settings has a potential for early diagnosis of ocular disorders such as dry eye disease, low-cost screening, and surveillance of at-risk subjects. However, current minimally-invasive rapid tear analysis systems for point-of-care settings have been limited to assessment of osmolarity or inflammatory markers and cannot differentiate between dry ...

http://www.avehjournal.org doi:10.4102/aveh.v74i1.12 The meibomian glands of the upper and lower eyelids play a valuable role in secreting the lipid layer of the tear film. Disturbances in meibomian gland function may result in altered secretion and variations in tear composition which may lead to meibomian gland dysfunction and evaporative dry eye, leading to ocular discomfort. To diagnose and...
