Translation and validation of the Portuguese version of a dry eye disease symptom questionnaire.

Purposes:: A symptom questionnaire is an important tool used to quantify and qualify the impact of a disease on a patient's related quality of life and to estimate the prevalence of a certain condition within a population. Ophthalmologists frequently encounter patients with dry eye disease (DED), and therefore, evaluating the symptoms reported by these patients influences diagnosis, therapeutic monitoring, and evaluations of disease progression. The latest consensus on dry eye (Dry Eye Workshop, DEWS), published in 2007, led to the standardization of several questionnaires and a better understanding of the prevalence, severity, and overall effect of DED on the patient's quality of life.
