OccuLogix, Inc. is an in-vitro diagnostic company. The Company is commercializing a tear testing platform, the TearLab Osmolarity System that enables eye care practitioners to test for highly sensitive and specific biomarkers using nanoliters of tear film at the point-of-care. Its first product measures tear film osmolarity for the diagnosis of Dry Eye Disease (DED). The TearLab Osmolarity System enables the rapid measurement of tear osmolarity in the doctor's office, a quantitative and highly specific biomarker that has been shown to correlate with DED. On October 6, 2008, the Company acquired the remaining minority interest in TearLab, Inc.
