方法：采用经真菌培养均为阳性的真菌性角膜炎患者的角膜标本38例，常规固定脱水透明浸蜡，进行4μm石蜡切片，脱蜡至水，选用异硫氰酸荧光素(FITC)荧光法和过碘酸雪夫氏染色法(PAS)进行染色对比。

结果：异硫氰酸荧光素法检测阳性率为97.4%(37/38)，过碘酸雪夫氏染色法检测阳性率为86.8%(33/38)。结果比较有统计学差异(P<0.001)。

结论：异硫氰酸荧光素法镜检真菌性角膜炎优于过碘酸雪夫氏染色法镜检。

METHODS:Thirty-eight cases with fungal keratitis were diagnosed by positive fungal culture. Corneal specimens of these cases were conventionally fixed, dehydrated and dipped in wax for 4μm paraffin sections, then subject to conventional dewaxing to water. The results of fluorescein isothiocyanate(FITC)and periodic acid-Schiff(PAS)staining were compared.

RESULTS: Positive detection rate of FITC staining was 97.4%(37/38), positive detection rate of PAS staining was 86.8%(33/38), with statistically significant difference(P<0.001).

CONCLUSION: FITC staining method is simple, fast, accurate, andhas high positive rate. It is superior to PAS staining, and is worth of promoting.
