目的：探讨在因屈光介质因素而首诊为视力骤降待查的患者中，应用OCT检查来判断视网膜动脉阻塞这类眼科急症的可行性和临床意义。

方法：回顾分析我院78例因视力骤降待查接受OCT检查并最终通过FFA检查确诊的病例。以FFA检查作为判断标准，以OCT检查作为待评价的检查手段，并用软件统计OCT的灵敏度、特异度和总符合率。同时统计分析两种检查方法从门诊医生开出检查单到报告给出的用时差异。

结果：OCT检查的灵敏度、特异度和总符合率均相当高，分别为100%，94.1%和98.4%。而在从门诊医师开出检查单到报告给出的用时上，OCT检查的时间明显短于FFA，其差异有统计学意义(P=0.000)。

结论：临床上对于因屈光介质因素而首诊为视力骤降待查的患者，应首先使用OCT检查来判断是否为视网膜动脉阻塞类疾病，以便更快地收治患者，为抢救视力赢得时间。

AIM: To investigate the application of optical coherence tomography(OCT)examination to determine the feasibility and clinical value of retinal artery occlusion of this kind of emergency among the eyesight drops suddenly patients awaiting diagnosis due to refractive medium.

METHODS:Seventy-eight eyesight drops suddenly and awaiting diagnosis patients accepting OCT inspections and confirmed by fundus fluoresceai angiography(FFA)in our hospital were retrospectively analyzed. With FFA examination as the judging standard and with OCT examination as the evaluation means of inspection, the statistics of OCT sensitivity, specificity and accuracy were counted using the statistical software. The statistics of method sensitivity and the total coincidence rate, specific degrees were counted using statistical software, then to statistically analyze the time difference of two methods from the clinic doctors prescribed checklist to report was given.

RESULTS:The sensitivity of OCT examination, specific degrees and the total coincidence rate were very high, 100%, 94.1% and 98.4%, respectively. From the clinic physicians prescribe the checklist to report available, the OCT examination time significantly shorter than the FFA(P=0.000), the difference was statistically significant.

CONCLUSION: Clinically to the eyesight drops suddenly patients awaiting diagnosis due to refractive medium, OCT examination should be used first to determine whether for retinal artery obstruction diseases, in order to more quickly treat patients and to win time of rescue vision.
