  1. Fulltext. Self-reported assessment of dry eye in a population-based setting.

    Article - En anglais

    Fulltext.

    Purpose

    To report on a subjective dry eye assessment method for use in large-scale research, to evaluate its application in a population-based study of dry eye among elderly persons in the United States, and to apply novel techniques to improve simple questionnaire item summaries.

    Methods

    A dry eye questionnaire was administered to a population-based sample of 25219 volunteers ages 65 to 84 years in Salisbury, Maryland.

    Individual symptoms and signs, counts of symptoms and signs, and latent class model summary of item responses were evaluated for validity and internal consistency.

    Results

    Approximately 15% of participants reported experiencing one or more of six dry eye symptoms often or all the time ; 20% reported experiencing three or more symptoms sometimes, often or all the time.

    Four groups were derived on the basis of symptomatology, using latent class analysis.

    The groups exhibited face validity, revealed symptom patterns that added specificity to simple symptom counts, and were qualitatively similar when derived separately within population subgroups.

    Internal consistency was moderate (Cronbach's alpha 0.61), indicating some variability in reporting.

    Conclusions

    Dry, eye symptoms are commonly reported in a representative elderly population.

    Symptom data were moderately consistent, suggesting their usefulness for dry eye assessment if properly summarized. (...)
