| Summary: |
Purpose: The aim of
the paper was to describe the prevalence and the role of
Demodex folliculorum and Demodex brevis in the
pathogenesis of chronic blepharitis.
Material and methods: Examinations were carried
out on a group of 435 people aged from 3 to 96 years. A
sample of four eyelashes were taken aseptically from
each individual and later studied under a light
microscope. Infection of Demodex 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 people aged from 3 to 15 years;
34% of the people aged from 19 to 25 years; 69% of the
people aged from 31 to 50 years; 87% of the people aged
from 51 to 70 years and 95% of the people aged from 71
to 96 years. It has been observed that 58% of the people
infected with Demodex suffer from chronic blepharitis.
It was also found that Demodex frequently occurs among
people taking care of the elderly and among students of
the Medical School.
Conclusions: (1) Demodex folliculorum and Demodex
brevis are an etiological factor in chronic blepharitis.
(2) With age the prevalence of infection of Demodex
rises. (3) People taking care of the elderly and
students of Medical Schools are at higher risk of being
infected with Demodex. |
