Analysis on the cause of retinal detachment after vitrectomy for open ocular trauma

Objective To analyze the causes of retinal detachment in patients with open ocular trauma after vitrectomy. Methods The clinical data of 129 patients with open ocular trauma underwent vitrectomy from Jul. 2013 to Jul. 2018 were retrospectively analyzed. A total of 114 patients in the non-retinal detachment group and 15 patients in the retinal detachment group were included. The cause of retinal detachment after vitrectomy for open ocular trauma were analyzed. Results There was no significant difference in gender, age or type of injury between the two groups (P>0.05). The factors of postoperative retinal detachment were related to combined with proliferative vitreoretinopathy (PVR), retinal detachment, operation time and intraoperative combined therapy. In the retinal detachment group the incidence of posperative retinal detachment in patients of PVR was higher than that in the non-retinal detachment group (P=0.002). The difference of preoperative incidence of retinal detachment (P=0.032) and later operation time (P<0.001) were statistically significant. The proportion of intraoperative scleral cryotherapy and retinotomy in the retinal detachment group (P=0.020, 0.000) was higher than that in the non-retinal detachment group during the operation. Conclusion PVR, preoperative retinal detachment, delayed surgery and over-operation during surgery are the main factors of retinal detachment after open ocular trauma surgery.
