螨虫性睑缘炎是由螨虫感染引起的特殊形式的睑缘炎.感染眼睑的毛囊蠕形螨和皮脂腺螨分别寄生于睫毛毛囊和皮脂腺内,当其感染数量较多或受局部各种因素的影响时就会导致睫毛毛囊和睑板腺病变,产生一系列的临床症状与体征.结合临床表现和螨虫检测是诊断螨虫性睑缘炎的主要依据.对于有明显症状和体征的螨虫性睑缘炎患者需要进行及时治疗以避免严重并发症的产生.本文从蠕虫性睑缘炎的流行病学、发病机制、病理改变、临床表现、临床诊断、治疗和预防等方面进行综述,以期为螨虫性睑缘炎的研究提供参考.“,”Demodex blepharitis is a special form of blepharitis caused by Demodex.Demodex folliculorum and Demodex brevis that infect the eyelids are parasitic on the hair follicles and sebaceous glands,respectively.When the number of infections is large or local factors affect the hair follicle and meibomian glands,a series of clinical symptoms and signs are produced.The main diagnosis of Demodex blepharitis needs to combine clinical manifestations and Demodex detection.Patients with obvious symptoms and signs need timely treatment.This study reviewed the epidemiology,pathogenesis,pathological changes,clinical manifestations,diagnosis,treatment and prevention of vermicular blepharitis in order to provide reference for the research of Demodex blepharitis.
