OBJECTIVE: Demodex acari is an obligate ectoparasite, and it is usually located in the human hair follicles, eyelash roots, and sebaceous glands. The aim of this study was to investigate the presence of Demodex infestation in chronic blepharitis cases that are resistant to therapy. METHODS: Patients who were admitted at the Istanbul Medipol University School of Medicine Hospital with a diagnosis of chronic blepharitis were included. All cases received conventional therapy at least three times. Three or four eyelash samples from patients with blepharitis were collected and examined under light microscopy. For the diagnosis, the presence of one or more Demodex parasites at 10× and 40× magnification by a light microscope was considered as positive for infestation. RESULTS: Overall, 153 cases were included in the study. Of the cases, 79 (51.6%) were males and 74 (48.4%) were females. The mean age was 43.1±9.7 years. The presence of D. acari in the follicles of the eyelashes in patients with chronic blepharitis was found in 69 (45.1%) cases. CONCLUSION: D. acari should be considered in patients with chronic blepharitis, especially in treatment-resistant cases. We believe that it would be useful to search for the parasite in patients with blepharitis prior to treatment on a routine basis.
