Objective To evaluate the influence factor of the prognosis of traumatic subretinal hemorrhage after vitreoretinal surgery. Methods The clinical data of 50 patients with traumatic subretinal hemorrhage who had undergone vitreoretinal surgery were retrospectively analyzed.All patients had ocular traumatic history and subretinal hemorrhage diagnosed by fundus and B-scan examination;the preoperative visual acuity was less than 0.1. According to different conditions, the traumatic eyes were treated with vitreo-retinal surgery, combined with lensectomy, retinotomy or silicone oil tamponade, respectively. The period of follow-up after surgery was 2-53 months, and the average period was 7.27 months. The corrected visual acuity and retinal reattachment at the last follow-up were observed. The visual acuity ge;0.1 was the standard of good prognosis; retinal reattachment was observed by indirect ophthalmoscope and color fundus photography.The prognostic factors mainly included type of injury,open or closed injury,the disease course, preoperative visual acuity, retinal detachment,hemorrhagic choroidal detachment,vitreous hemorrhage,the sites of submacular hemorrhage,methods of surgery.The relationships between those prognostic factors and visual acuity outcome or retinal reattachment were analyzed by chi;2test and logistic regression analysis. Results About 46.0% patients had good prognosis of the visualacuity. In the eyes with preoperative visual acuity of no light perception to hand moving and finger counting to 0.1, the rate of good visual acuitywas 34.2% and 83.3%, respectively; the difference between the two groups was significant ( chi;2=8.860,P=0.003). In the eyes with or without preoperative retinal detachment,the rate of good visual acuity was 37.5% and 80.0%, respectively; the difference between the two groups was significant ( chi;2=4.232,P=0.040). In the eyes with subretinal hemorrhage involving the macular fovea or not, the rate of good visual acuity was 34.4% and 66.7%,respectively; the difference between the two groups was significant ( chi;2=4.836,P=0.028).All the other prognostic factors had no obvious effect on the retinal reattachment after the surgery. Conclusion Preoperative visual acuity、retinal detachment and submacular retinal hemorrhage were the important influence factors associated with prognostic visual acuity of eyes with traumatic subretinal hemorrhage after vitreoretinal surgery.
