40例蠕形螨睑缘炎患者临床特点分析

Clinical Features Analysis of Demodectic Blephartis Observed in 40 Patients

对55例睑缘炎患者进行结膜刮片细胞学检查及蠕形螨检查,40例检出蠕形螨(Demodex),检出率为72.7%。40例蠕形螨睑缘炎患者的主要临床表现为结膜充血(37例),睑缘充血肥厚(40例),睫毛脱失乱生(39例),睫毛根部袖套样鳞屑(33例),结膜病变(37例),角膜病变(21例),睑板腺开口阻塞(18例),伴有面部痤疮、酒糟鼻等皮肤病变(19例),麦粒肿及霰粒肿(15例)。细胞学检查,27例可观察到炎性细胞以中小淋巴细胞浸润为主,提示为长期慢性炎症所致结膜改变。

Conjunctival scrapings for cytological examination and demodicid mite microscopic examination were performed in 55 cases of blephartis patients. Demodicid mites were detected in 40 cases, with a detection rate of 72.7%. The following signs/symptoms displayed among the 40 cases： conjunctival congestion（37）, eyelid hyperemia and hypertrophy（40）, eyelash epilation and abnormal growth（39）, eyelash root with sleeve-like scales（33）, conjunctival lesions（37）, corner lesions（21）, meibomian gland orifice occlusion（18）, accompanied with skin lesions as acne or acne rosacea（19）, hordeolum and chalazion（15）. Conjunctival scrapings for cytological examination in the 27 cases revealed medium- and small-sized lymphocyte-predominant inflammatory cells, indicating that the conjunctiva lesion was a result of chronic inflammation.
