RPS InflammaDry Detector™ to Determine MMP-9 Levels in Tears

The purpose of this clinical trial was to determine the sensitivity and specificity of InflammaDry compared with the clinical assessment of dry eyes. Patients were screened using clinical history and signs. Clinical history was performed using the Ocular Surface Disease Index (OSDI) and evaluated for clinical signs: * positive vital staining of the ocular surface, * decreased tear breakup time (TBUT), * reduced corneal sensitivity, and * decreased functional visual acuity Last, an independent health care professional masked to the clinical evaluation was asked to analyze each InflammaDry test result, independently confirming each result.
