ABSTRACT

Objective: To determine the prevalence of Demodex mites in patients with symptomatic multitreated chronic blepharoconjunctivitis and their clinical spectrum.
Methods: A retrospective, observational and descriptive study was performed. Patients with diagnosis of chronic blepharoconjunctivitis which received previous empiric treatment without symptomatic improvement were included. All patients had eyelash direct test and microbiological conjunctival secretion cultures.
Results: 302 patients were included. 176 (58.27%) were positive to Demodex, average age was 52.9 years with a range between 15 and 86 years. More frequent symptoms were: itching (73.86%), conjunctival discharge (64.77%), foreign body sensation (54.54%), red eye (47.72%) and epiphora (36.36%). More frequent signs were: lid margin thickening (94.31%), Meibomian glands dysfunction (86.36%), keratitis sicca (17.04%), madarosis (7.94%) and lid margin telangiectasia (6.81%).
Conclusion: Prevalence of Demodex folliculorum in patients with chronic multitreated blepharoconjunctivitis is similar to the prevalence of the same mite in patients with chronic blepharitis without previous empiric treatment.
