目的:通过对我院300例住院治疗的机械性眼外伤患者病历资料进行统计与回顾性分析,探讨机械性眼外伤患者急诊处理后的视力预后影响因素。方法:对300例机械性眼外伤患者的一般情况、眼别、受伤原因、急诊处理方式、入院视力、出院视力等进行记录和统计分析。结果:机械性眼外伤300例,男女比例约为8∶1,15～20岁年龄段男女比例最高,约为14∶1,发病高峰年龄在35～45岁和5～10岁。以眼球开放性外伤、眼和附属器挫伤最多见。在眼球开放性外伤中,以异物伤最多见。致伤原因以钝器伤、锐器伤为主,爆炸伤等原因较为少见。机械性眼外伤300例311眼的治疗方式中以眼内异物取出为主,其次为保守治疗,视力预后的主要影响因素是:致伤原因、是否伤后24h内处理。急诊等处理后,出院视力的提高具有显著性(P<0.05)。结论:机械性眼外伤300例致伤原因以钝器伤、锐器伤和爆炸伤最为常见。住院治疗的机械性眼外伤视力预后的主要影响因素是:致伤原因、是否伤后24h内急诊处理。

AIM:To discuss the major determinant factors of visual pro-gnosis of mechanical ocular trauma by statistical analysis and retrospective study of the 300 patients. ·METHODS:This is a retrospective study on 300 cases with mechanical ocular trauma in recent 5 years.We recorded and analyzed the following details:general state of health,left or right eye,cause of injury,whether treated in time,vision of admission,vision of discharge. ·RESULTS:Sex distribution:male 8/9,female 1/9. Most of patients fell in the age group of between 5-10 and 35-45,and with the highest sex distribution of 14:1 at the age group of 15-20. Open wound of eyeball,ocular and its appendages contusion were most frequently seen. Injury caused by foreign object was most frequently seen in open wound of eyeball. Most of patients had a significant visual improvement at the time of discharge (P<0.05). The major determinant factors of the visual prognosis after treatment were summarized as following:causes of the injury;whe-ther treated within 24 hours. ·CONCLUSION:Most of the ocular trauma comes from blunt injury,sharp instrument injury and explosion injury. The major determinant factors of the visual prognosis after treatment are summarized as following:cause of the injury,whether treated within 24 hours.
