目的 探讨非球内异物性角膜穿通伤致盲相关因素。方法 对158例角膜穿通伤患者的临床资料进行回顾性分析,讨论外伤后初诊时间、角膜裂口形状、有无色素膜脱出、有无前房积血等因素与盲目的关系。结果致盲危险性分别为:初诊时间<24h与>24h间OR=3.44;角膜裂口形状线形与非线形间OR=2.6:色素膜脱出有和无间OR=3.82;前房积血无与≤Ⅰ间OR=4.38,无与>Ⅱ间OR=11.93,>Ⅱ与≤Ⅱ间OR=2.73。结论 本组非球内异物角膜穿通伤患者致盲主要与初诊时间、角膜裂口形状、色素膜脱出、前房积血等因素密切相关(P<0.01),与年龄、性别无关(P>0.05)。
Objective To investigate the related factors of blindness in non-spherical intraocular corneal penetrating injury. Methods The clinical data of 158 patients with penetrating corneal penetrance were analyzed retrospectively to discuss the relationship between the time of initial traumatic injury, the shape of corneal tear, the presence or absence of pigmented membrane and the presence of hyphema and blindness. Results The risk of blinding were as follows: OR = 3.44 between 24h and> 24h after initial diagnosis; OR = 2.6 between linear and non-linear corneal cleft shape: OR = 3.82 with prolapse and no intermurial OR = 3.82; OR = 4.38, no OR> 11.93, OR> 2.73 between> II and 0.05) .
