Use of the Dry Eye Questionnaire to Measure Symptoms of Ocular Irritation in Patients With Aqueous Tear Deficient Dry Eye

Abstract

Symptoms of ocular irritation were frequent and intense among SS and KCS subjects. These symptoms often increased in intensity over the day, suggesting that open-eye conditions affect the progression of symptoms. Measurement of symptom frequency and diurnal intensity by the DEQ provides a sensitive tool that may be useful in clinical treatment trials for dry eye.
