AIM: To explore the risk factors of retinal detachment after stage II vitrectomy in patients with open ocular trauma.

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.
