眼外伤的流行病学分析及眼外伤评分的临床应用

Epidemiology characteristics and ocular trauma score in eye injuries

目的分析眼外伤的临床特点,应用眼外伤评分(OTS)对其进行预后评估。方法统计分析153例(156眼)眼外伤的性别、年龄、受伤时间、地点、初视力、治疗方案、随诊的终视力。并对伤眼进行OTS评分(对初视力、眼内炎发生情况、眼球破裂情况、是否为穿孔性伤口、有无视网膜脱离、瞳孔反射情况进行评估),根据OTS数据表推算出最终视力的概率;对比本组病例的终视力比率与OTS表的终视力概率。结果本研究病例终视力出现的比率与由OTS计算出的终视力(无光感,光感/手动,0.005～0.095,0.1～0.4,≥0.5)概率相比,无明显差异。终视力与初视力呈明显正相关(r=0.650,P<0.000)。OTS-1级的终视力在0.5者为0,OTS-5级的终视力为无光感(NLP)者也为0。结论对眼外伤最初眼部情况进行OTS评分可为患者及医生提供一个较为可靠的治疗依据及预后信息。

Objective To iuvestigate the clinic feature of pa- tients with eye injuries and assess prognostic value of the ocular trauma score （OTS） in them. Methods In 153 patients （156 eyes） with eye injuries, certain numerical values rendered to the OTS variables （ visual acuity, rupture, endophthalmitis, perforating injury, retinal detachment and afferent pupillary defect） at presentation were summarized and converted into OTS categories. The likelihood of the final visual acuities in the OTS categories were calculated and compared with those in the OTS study. Results The likelihood of the final visual acuities （ no light perception NLP, light perception LP/hand motion HM, 1/200 to 19/200, 20/200 to 20/50, and 〉20/40） in the OTS categories （ 1 through 5） in this group were similar to those in the OTS study group. The final visual acuity had a positive correlation significantly to the first visual acuity. No study eye was in the both category-5 with NLP visual acuity and category-1 with 〉 20/40 visual acuity. Conclusion OTS calculated at initial examination may provide prognostic information in eye mjunes.
