TearLab recently reported interim results of a multi-center dry eye disease (DED) prevalence study carried out in the UK at four National Health Service (NHS) hospitals.
The study compared the effectiveness of the TearLab Osmolarity test to other traditional methods of diagnosing DED. The study began in March and its interim phase was completed in June. The interim clinical trial results showed that osmolarity had the highest agreement with the International Dry Eye Workshop (DEWS) findings, which is a composite score based on several tests, and that traditional tests like staining and TBUT do not correlate well with the presence of the disease.
“The interim results of this study could have far-reaching consequences for the evaluation, diagnosis, and management of dry eye disease in the UK,” lead investigator and consultant ophthalmologist Francesca Harman, from Hillingdon Hospital, said in a statement.
