Brief Summary  

The International Dry Eye Workshop II 2017 defines dry eye disease[1] (DED) 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”. The symptoms of DED include ocular burning, foreign body sensation, soreness, stinging, irritation, reduced visual acuity, photophobia, and ocular pain. The burden of DED can vary from mild discomfort to severe complaints that impact daily activities, reduce the quality of life, and have significant socioeconomic implications. The prevalence of DED increases with age and ranges from 5% to 50%

Accurate diagnosis of DED is complex and requires the application of a battery of tests, including questionnaires of patient-reported symptoms, tear film break-up time (TFBUT),  Schirmer test, ocular surface staining, and meibomian gland functionality. However, most of the tests lack consistency and reliability for diagnosing DED; therefore, they are subject to clinical interpretation based on experience. The lack of a strong association between the signs and symptoms of DED is another challenge clinicians face in diagnosing and following-up patients with the disease. Numerous ancillary diagnostic tests have been developed to overcome these challenges, including several patient-reported DED-specific questionnaires and new tools enabling the quantification of tear film characteristics.

DiagnoTear has developed a diagnostic technology that is based on semiquantitative analysis of the tear film. The company’s first product consists of a multivariate algorithm calculates a final numeric value that is based on values of 5 parameters that include 3 biomarkers within the tear content: albumin, lactoferrin and lysozyme and takes into consideration age and gender. The data provides the physician with actionable information regarding treatment strategy. As this is personalized, it is also a powerful means for follow up of response to treatment.

The selection of those three specific markers was based on results from 3 different clinical trials performed by DiagnosTear in which more markers have been tested. In those studies, the effectiveness of the developed assay was tested in diagnosing DED patients and comparing their results with results obtained from healthy subjects. Furthermore, the sensitivity and specificity of the results were compared to the 4 standard of care benchmark tests, assessing both signs and symptoms.
