Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, observational case series to determine the clinical utility of tear osmolarity and other commonly used objective tests to diagnose dry eye disease, as well as to establish referent values for objective tests of the disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, observational case series to determine the clinical utility of tear osmolarity, tear film breakup time, corneal fluorescein staining, conjunctival lissamine green staining, Schirmer's test without anesthesia, Bron/Foulks meibomian glan grading and the ocular surface disease index to diagnose dry eye disease, as well as to establish referent values for objective tests of the disease. Patients were recruited across sites in the EU and US from the general clinical population.
