目的：分析眼外伤的流行病学特点，根据美国眼外伤协会制定的眼外伤评分(OTS)标准，对眼外伤进行国际标准化分级，以对眼外伤的严重程度及预后提供客观准确的信息，指导我们准确而快速地制定出更为合理的诊断和治疗方案。

方法：统计251例252眼眼外伤患者的基本情况(性别、年龄、眼别、受伤时间、受伤类型、致伤物及并发症等)，对眼外伤患者伤眼进行OTS评分(对就诊初视力、是否有眼球破裂、眼内炎、是否为穿孔伤、是否伴发视网膜脱离、是否合并相对传入性瞳孔阻滞等进行评估)，根据OTS评分数据表推算出最终视力的概率； 对比本组患者的终视力概率与OTS评分表的终视力概率。对不同级别眼外伤患者的评分进行比较。

结果：本研究计算出的终视力概率与由美国眼外伤协会提供的OTS评分表计算出的终视力(无光感、光感/手动、0.005～0.095，0.1～0.4，≥0.5)的概率相比，没有统计学差异(P>0.05)。终视力与初视力呈明显正相关(r=0.772，P=0.000)。OTS-1级的终视力是0.5者的例数为0，OTS-5级的终视力为无光感的例数也为0。

结论：对眼外伤患者进行OTS评分可以很好地为眼科医生对伤情初判及快速制定出治疗方案提供较好的帮助。

AIM: To analyze the epidemiological characteristics of ocular trauma, classify ocular trauma internationally according to OTS standards set by US Association of Ocular Trauma, and to provide objective and accurate information on the severity and prognosis of ocular trauma, guide us to work out the most reasonable diagnostic and therapeutic programs accurately and quickly.

METHODS: Statistics of 251 cases(252 eyes)with ocular trauma on basic information( on gender, age, left or right eye, injury time, injury types, vulnerants and complications, etc.), were summarized and converted into OTS categories(on early clinical vision, with or without ocular rupture, endophthalmitis, perforating injury, retinal detachment, merging to relative afferent pupillary defect, etc.). The likelihood of the final visual acuity was calculated according to the OTS data sheet and compared with that in the OTS study. Scores of patients in different ocular trauma level were compared.

RESULTS: The likelihood of the final visual acuity of this research showed no significant difference from the final visual acuity calculated according to OTS data sheet(no light perception, light perception/hand motion, 0.005-0.095, 0.1-0.4, ≥0.5). The final visual acuity showed positive correlation significantly to the early visual acuity(r=0.772,P=0.000). The case number of final visual acuity at 0.5 in category-1 of OTS was 0. So was the case number of final visual acuity with no light perception in category-5 of OTS.

CONCLUSION: OTS may contribute greatly to initial diagnosis and therapeutic schedule in eye injuries.
