PURPOSE: The aim of the paper was to describe the prevalence and the role of Demodex folliculorum and Demodex brevis in the pathogenesis of @entity14985 . MATERIAL AND METHODS: Examinations were carried out on a group of 435 @entity1 aged from 3 to 96 years. A sample of four eyelashes were taken aseptically from each individual and later studied under a light microscope. @entity281 was classified on the basis of presence of mature and larval forms or after observing chitinous exuviae affixed to the studied eyelashes. RESULTS: It has been concluded that Demodex occurs among: 13% of the @entity1 aged from 3 to 15 years; 34% of the @entity1 aged from 19 to 25 years; 69% of the @entity1 aged from 31 to 50 years; 87% of the @entity1 aged from 51 to 70 years and 95% of the @entity1 aged from 71 to 96 years. It has been observed that 58% of the @entity1 infected with Demodex suffer from @entity14985 . It was also found that Demodex frequently occurs among @entity1 taking care of the elderly and among students of the Medical School. CONCLUSIONS: (1) Demodex folliculorum and Demodex brevis are an etiological factor in @entity14985 . (2) With age the prevalence of @entity281 rises. (3) @entity1 taking care of the elderly and students of Medical Schools are at higher risk of being infected with Demodex.
