Brief Summary
|
The International Dry Eye Workshop II 2017 defines dry eye disease (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.
