Assessment of Demodex Sp. Prevalence in Blepharitis Patients: Comparison of Light and Fluorescence Microscopy Techniques

Abstract

Objective Demodex mites, the most prevalent human ectoparasites, are frequently associated with blepharitis. Despite their widespread occurrence, Demodex blepharitis remains underdiagnosed and often overlooked in clinical practice. This study investigates the prevalence and density of Demodex species in blepharitis patients, compares the diagnostic effectiveness of light and fluorescence microscopy, and examines the relationship between Demodex infestation and associated clinical symptoms. Methods A total of 240 people, 120 patients with blepharitis and 120 controls, were included in the study. Eyelash samples from both groups were analyzed using light microscopy and fluorescence microscopy to detect Demodex mites. Additionally, clinical and demographic data were gathered through a structured questionnaire. Results Demodex spp. were detected in 79.2% (95/120) of blepharitis patients by light microscopy and in 80.8% (97/120) by fluorescence microscopy. The prevalence of Demodex spp. was significantly higher in patients with blepharitis compared to controls (p<0.001). Fluorescent microscopy exhibited a higher detection rate than light microscopy (p=0.012). Conclusions Demodex mites play a significant role in ocular disorders, particularly blepharitis. Timely and accurate diagnosis, along with appropriate treatment, is essential to prevent the adverse mental and physical health impacts associated with Demodex blepharitis.
