真菌性角膜炎病原学诊断

目的分析角膜涂片细胞学检查、真菌培养、角膜共焦显微镜在真菌性角膜炎诊断中的应用价值。方法对324临床诊为真菌性角膜炎患者进行涂片细胞学检查、真菌培养和角膜共焦显微镜检查,并对其检查的阳性率进行汇分析,以探讨病原学诊断在真菌性角膜炎诊断中的应用价值。结果324份标本中,细胞学检查阳性者168例(51.85%),真菌培养阳性者212例(65.43%),角膜共焦显微镜检查阳性者277例(85.63%)。结论角膜共焦显微镜检查在真菌性角膜炎诊断中有重要意义,是一种快速、有效、无损伤、可以直接在活体角膜上观察真菌菌丝的检查方法,较真菌培养和细胞学检查对真菌性角膜炎的早期诊断,治疗具有更重要的临床价值。

Objective To reviwe the possibility of using confocal microscope in the living eye. Methods The 324infected corneas were examined by confocal microscope and Retrospective analyses of the fungal culture positive rate. Results The number of positive culture by smears was 168 （51.85%） and by biopsies was 212 （65.43%） of 324 cases, by confocal microscope was 277 （85.63%）. Conclusion Confocal microscope can be a rapid, effective and nonivasive imaging technique, and it is helpful in the diagnosis, treat- ment of fungal keratitis.
