<p> <strong class="sub-title"> Objective: </strong> To collect questionnaire data from patients in a large clinical population that would allow for an estimate of the prevalence of self-reported symptoms of dry eyes. </p> <p> <strong class="sub-title"> Methods: </strong> A 13-point questionnaire (The Canada Dry Eye Epidemiology Study, CANDEES) was mailed to all optometric practices in Canada in October 1994, with the request that it be completed by 30 successive nonselected patients. </p> <p> <strong class="sub-title"> Results: </strong> Four hundred fifty sets of questionnaires (total, 13,517) were analyzed (a 15.7% return rate) from patients aged from < 10 years to > 80 years; 55% were in the 21- to 50-year age group; 60.7% were female; and 24.3% were contact lens wearers. A total of 28.7% reported dry eye symptoms, of whom 24.2% reported concurrent dry mouth, 24.5% had worse symptoms in the morning, 30.3% reported concurrent lid problems, and 35.7% reported a history of allergies. Of the 3716 patients reporting symptoms, 62 (1.6%) were in the "severe" category and 290 (7.8%) were in the "constant but moderate" category. Contact lens wear, concurrent allergies, dry mouth, lid problems, or use of medications increased the chance of a patient reporting dry eye symptoms. </p> <p> <strong class="sub-title"> Conclusions: </strong> The prevalence of patients reporting any level of symptoms of dry eyes was approximately 1 in 4; severe symptoms were reported by 1 in 225 patients. </p> </div> </div> <p class="disclaimer" id="disclaimer"> <a href="/disclaimer/" target="_blank" ga_category="literature_resources" ga_action="disclaimer_link" ga_label="under_abstract">PubMed Disclaimer</a> </p> <div class="similar-articles" id="similar"> <h2 class="title"> Similar articles </h2> <ul class="articles-list" id="similar-articles-list"> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/11473162/" ref="article_id=11473162&linksrc=similar_articles_link&ordinalpos=1" data-ga-category="similar_article" data-ga-action="11473162" data-ga-label=""> Characterization of ocular surface symptoms from optometric practices in North America. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Begley CG, Chalmers RL, Mitchell GL, Nichols KK, Caffery B, Simpson T, DuToit R, Portello J, Davis L.</span> <span class="docsum-authors short-authors">Begley CG, et al.</span> <span class="docsum-journal-citation full-journal-citation">Cornea. 2001 Aug;20(6):610-8. doi: 10.1097/00003226-200108000-00011.</span> <span class="docsum-journal-citation short-journal-citation">Cornea. 2001.</span> <span class="citation-part">PMID: <span class="docsum-pmid">11473162</span></span> </div> </div> </li> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/9634970/" ref="article_id=9634970&linksrc=similar_articles_link&ordinalpos=2" data-ga-category="similar_article" data-ga-action="9634970" data-ga-label=""> CANDEES.
