目的：探究开放性眼外伤患者Ⅱ期玻璃体切除术后发生视网膜脱离的危险因素。

方法：回顾性分析。纳入2020-04/2023-07我院就诊行Ⅱ期玻璃体切除术的开放性眼外伤患者278例278眼，根据术后视网膜脱离情况分为脱离组48眼与未脱离组230眼。比较两组患者基本临床情况，并分析影响患者视网膜脱离的因素。

结果：单因素分析结果显示，两组患者眼外伤伤口长度、受伤区域、受伤后手术时间、视网膜脱离/病变史均有差异(均P<0.05)。Logistics多因素回归分析显示，伤口长度大于10 mm、受伤后手术时间超过1 wk、有视网膜脱离/病变史是导致开放性眼外伤患者Ⅱ期玻璃体切除术后视网膜脱离的危险因素(均P<0.05)。

结论：开放性眼外伤患者Ⅱ期玻璃体切除术后发生视网膜脱离主要与创伤严重程度、受伤后手术时间以及眼部视网膜病变史有关，患者需尽早接受手术治疗。

METHODS: Retrospective analysis. Totally 278 patients(278 eyes)with open ocular trauma who received stage II vitrectomy in the hospital were included from April 2020 to July 2023. According to the postoperative retinal detachment status, they were divided into detachment group(48 eyes)and non-detachment group(230 eyes). The basic clinical conditions of the two groups of patients were compared, and the factors affecting retinal detachment were analyzed.

RESULTS: Univariate analysis revealed that there were statistical differences in wound length, injured area, surgical time after injury, and history of retinal detachment/lesion between the two groups(all P<0.05). Logistics multivariate regression analysis showed that wound length greater than 10 mm, surgical time after injury more than 1 wk, and history of retinal detachment/lesion were risk factors for retinal detachment in patients with open ocular trauma after stage II vitrectomy(all P<0.05).

CONCLUSION: The occurrence of retinal detachment in patients with open ocular trauma after stage II vitrectomy is mainly related to the severity of trauma, surgical time after injury and history of ocular retinopathy. It is necessary to perform surgical treatment for patients as soon as possible.
