目的探讨非眼内异物角膜穿孔伤盲的相关因素。方法对158例角膜穿孔伤患者的临床资料进行回顾性分析。结果初诊时间＜24h与＞24h、角膜伤口线型与非线型，有无葡萄膜脱出，有无前房积血之间出院时致盲具有显著性差异（P＜0．01）。结论本组非眼内异物角膜穿孔伤患者致盲主要与上述4因素密切相关，与年龄、性别无关（P＞0．05）。
Objective To investigate the related factors of non-intraocular foreign body corneal perforation injury. Methods The clinical data of 158 patients with corneal perforation were retrospectively analyzed. Results The time of initial diagnosis was <24h and> 24h. There were significant differences in the linear and non-linear corneal wounds, the presence or absence of uveal detachment, and the presence or absence of anterior chamber hemorrhage between blindness and discharge at discharge (P <0.01). Conclusion This group of patients with non-intraocular foreign body corneal perforation in patients with blindness mainly related to the above four factors, age and gender had no relationship (P> 0.05).
