方法：前瞻性研究。选取2013-12/2016-01期间经我院眼科收治的开放性眼外伤患者62例62眼作为研究对象，采取随机分组的方式将其分为观察组和对照组，每组31例31眼。观察组患者于伤后2～4d内进行玻璃体手术治疗，对照组患者于伤后1～2wk内进行玻璃体手术治疗，对比两组患者的术前眼部损伤情况和术后治疗效果、并发症以及视力恢复情况。

结果：两组患者手术前角膜裂伤、视网膜脱落、玻璃体积血以及晶状体破裂等眼部损伤状况比较差异均无统计学意义(P>0.05)； 对比两组患者的预后状况发现，观察组患者的治疗效果显著优于对照组，观察组患者的术后并发症发生情况显著低于对照组，同时观察组患者术后视力恢复状况显著优于对照组，差异均具有统计学意义(均P<0.05)。

结论：开放性眼外伤患者手术时机与预后状况之间存在明显相关性，早期对患者行玻璃体手术有利于达到更好的治疗效果，减少并发症、帮助患者术后视力恢复。

METHODS: Sixty-two cases(62 eyes)of open ocular trauma patients admitted to our hospital during the period from Dec. 2013 to Jan. 2016 were selected as the research subjects. The patients were randomly divided into observation group and control group, 31 cases(31 eyes)in each group. Observation group patients were treated in 3d of vitreoretinal surgery after injury. The patients in the control group underwent vitrectomy within 1 to 2wk after injury of pars plana. Two groups of patients with preoperative eye injury and postoperative treatment effect, complications and visual acuity recovery were compared.

RESULTS: Two groups of patients with preoperative corneal laceration, retinal detachment, vitreous and lens rupture eye injury situation were no significantly difference(P<0.05). The prognosis of the two groups were compared. The treatment effect of the patients in the observation group were significantly better than the control group. The observation group of patients with postoperative complications were significantly lower than that of control group at the same time. The observation group patients' postoperative visual acuity recovery was significantly better than the control group and the differences were statistically significant(P<0.05).

CONCLUSION: Open ocular trauma surgery was significantly correlated the between operation time and prognosis status. It is beneficial to achieve better therapeutic effect on the patients with vitreous body surgery. It also can reduce complications and help the recovery of visual acuity patients after operation.
