OBJECTIVE
To determine the presence of Demodex spp. in the eyelashes' pilosebaceous unit in volunteers of one campus of a private university.
MATERIALS AND METHODS
The volunteers underwent anamnesis, biomicroscopic study and samples were taken of 8 eyelashes, 2 of each eyelid of both eyes. The eyelashes were mounted on a slide and observed under a light microscope to determine the presence and quantity of mites.
RESULTS
200 volunteers were recruited, determining the prevalence of Demodex spp. in 54 (27%) of them. Of the positive cases, 40 (74.1%) presented signs and/or symptoms of blepharitis, 43 (79.7%) presented the mite in one eye and an average infestation rate of 0.65 Demodex spp. per eyelash was obtained.
CONCLUSIONS
Approximately one in four of the volunteers studied without a diagnosis of blepharitis was a carrier of the parasite, of which a significant percentage presented some type of sign and/or symptom of this pathology which was related to a higher rate of infestation (p<0.05).
目的
在一所私立大学校园的志愿者中，确定睫毛的毳毛皮脂腺单位中是否存在蠕形螨属。
材料和方法
志愿者接受了病史调查、生物显微镜检查，并从每只眼睛的 8 根睫毛中各取 2 根进行检查。将睫毛装在载玻片上，在光学显微镜下观察以确定螨虫的存在和数量。
结果
共招募了 200 名志愿者，其中 54 名（27%）存在蠕形螨属。在阳性病例中，40 名（74.1%）有睑缘炎的体征和/或症状，43 名（79.7%）在一只眼中有螨虫，平均每根睫毛有 0.65 个蠕形螨属。
结论
在所研究的志愿者中，大约每四人中就有一人没有被诊断为睑缘炎，但携带了寄生虫，其中相当一部分人表现出这种疾病的某种类型的体征和/或症状，这与更高的感染率有关（p<0.05）。
