方法：回顾性病例分析。收集郑州大学第一附属医院眼科入院治疗的眼外伤者876例905眼，其中对照组(2019-01/06)545例565眼，研究组(2020-01/06)331例340眼。比较两组患者年龄、性别、受伤地点、受伤原因、居住地、受伤类型等信息。

结果：研究组眼外伤住院人数较对照组减少39.3%，对照组和研究组年龄均呈双峰样分布，分别为0～10岁(20.55%，21.45%)和41～50岁(17.98%，19.03%)占比最高，两组年龄分布无差异(P=0.907)。对照组和研究组均以男性为主，占比80.37%，83.69%(P=0.219)。研究组居家受伤比例(28.40%)高于对照组(11.38%)(P<0.001)。研究组机械性眼外伤占比(98.19%)高于对照组(95.60%)(P=0.041)，开放性眼外伤占比(85.54%)高于对照组(76.58%)(P=0.001)，无光感者占比(18.86%)高于对照组(9.53%)(P<0.001)。

结论：新型冠状病毒肺炎疫情期间，眼外伤住院患者显著减少，机械性眼外伤是主要眼外伤类型，在流行病暴发期间，仍应加强眼外伤的防护意识。

METHODS: A retrospective case analysis. Totally 876 cases(905 eyes)of ocular trauma were analyzed in this study, including 545 cases(565 eyes)from January to June 2019 were enrolled ascontrol group, and 331 cases(340 eyes)from January to June 2020 were enrolled in the research group. Information regarding age, sex, location of injury, cause of injury, place of residence, and type of injury were collected and analyzed.

RESULTS: The number of hospitalisation for ocular trauma in the research group decreased by 39.3% compared with the control group. The age distribution of patients showed a double peak, at 0-10 years(20.55%, 21.45%)and 41-50 years(17.98%, 19.03%)in the control group and research group, respectively. There was no statistically significant difference in the age distribution between the two groups(P=0.907). Men were predominantly injured in both the control and the research groups, accounting for 80.37% and 83.69%, respectively(P=0.219). The proportion of home injuries in the research group(28.40%)was higher than the control group(11.38%)(P<0.001). The proportion of mechanical eye injuries in the research group(98.19%)was higher than the control group(95.60%)(P=0.041), and the proportion of open globe injuries(85.54%)was also higher than the control group(76.58%)(P=0.001). The proportion of patients with no light perception in the research group(18.86%)was higher than that of the control group(9.53%)(P<0.001).

CONCLUSION: During the COVID-19 epidemic period, the total number of ocular trauma cases was significantly reduced. Mechanical eye injuries are still the main type for hospitalisation of patients with eye injuries. The awareness of eye injury prevention should be strengthened during the period of epidemic.
