摘要目的：探讨睑缘炎相关角结膜病变（BKC）的临床症状、体征，分析误诊原因。方法回顾性分析安顺市人民医院眼科2014年6月至2016年6月门诊最终诊断为BKC的患者88例的临床资料，根据患者的症状、体征与BKC诊断标准分析误诊原因。结果88例BKC患者中误诊59例，误诊率67．04％。安顺市人民医院误诊10例（12．19％），其中住院医师误诊6例（6．81％），主治医师误诊2例（2．27％），副主任及以上医师误诊1例（1．13％）；外院误诊49例（55．68％），其中三级医院误诊8例（9．09％），二级医院误诊23例（26．13％），一级医院及以下误诊18（20．45％）；误诊疾病包括病毒性角膜炎14例（15．90％），慢性睑缘炎13例（14．77％），睑板腺功能障碍（MGD）10例（11．36％），干眼8例（9．09％），慢性结膜炎6例（6．81％），过敏性结膜炎5例（5．68％），边缘性角膜溃疡3例（3．40％）。结论 BKC的临床特点与病毒性角膜炎、慢性睑缘炎、MGD、干眼等疾病有相似及重叠之处，加之临床医生对该病的认识及重视不足，临床极易误诊误治，特别是基层医师。临床中应重视患者的病史、症状，裂隙灯显微镜详细检查睑缘、结膜及角膜等情况，最大程度的减少误诊、误治。

abstractsObjective To explore the clinical symptoms,signs,and analysis of misdiagnosis of blephaokera-toconjunctivitis(BKC).Methods The clinical data of 88 patients with BKC in our hospital from June 2014 to June 2016 were retrospectively analyzed.Based on the patients'symptoms,signs and BKC diagnostic criteria,the causes of misdiagnosis were analyzed.Results In 88 patients with BKC,59 cases were misdiagnosed,the misdiagnosis rate was 67.04%.The People's Hospital of Anshun misdiagnosed 10 cases(12.19%),among which resident misdiagnosed 6 cases(6.81%),attending physician misdiagnosed 2 cases (2.27%),deputy director and the above physician misdiagnosed 1 case (1.13%);outer court misdiagnosed 49 cases (55.68%),among which three level hospital misdiagnosed 8 cases(9.09%),II level hospital misdiagnosed 23 cases(26.13%),a level hospital and the following misdiagnosed 18 cases (20.45%);misdiagnosis disease including virus sex keratitis 14 cases(15.9%),chronic blepharitis in 13 cases(14.77%),the meibomian gland dysfunction(MGD)in 10 cases(11.36%),8 cases of dry eye(9.09%),6 cases of chronic conjunctivitis(6.81%),allergic conjunctivitis 5 cases (5.68%),marginal corneal ulcer in 3 cases(3.4%).Conclusion The clinical characteristics of BKC and viral keratitis,chronic blepharitis, MDGS and dry eye disease are similar and overlap,and clinicians are lack of knowledge and awareness of the disease, the clinical misdiagnosis and mistreatment is vulnerable,especially in primary care doctors.We should pay attention to the clinical patients'history,symptoms,slit lamp microscope examination of palpebral and conjunctival and corneal conditions,etc.thus to reduce misdiagnosis and avoid medical disputes.
