Timing of stage Ⅱ vitrectomy in patients with open ocular trauma
Abstract
AIM:To observe the clinical efficacy of vitrectomy at different times for open ocular trauma and explore the timing of stage Ⅱ vitrectomy.METHODS: Retrospective case series study. A total of 60 cases(60 eyes)with open ocular trauma who visited our ophthalmology department from June 2022 to February 2023 were included. They were divided into treatment group A(interval ≤14 d)and treatment group B(interval >14 d)based on the interval between the stage Ⅰ emergency treatment surgery and the stage Ⅱ vitreoretinal surgery. Among the 32 cases(32 eyes)in the treatment group A, 16 eyes(50%)had eyeball rupture, 13 eyes(41%)had penetrating injury, and 3 eyes(9%)had perforating injury. Among the 28 cases(28 eyes)in the treatment group B, 15 eyes(54%)had eyeball rupture, 12 eyes(43%)had penetrating injury, and one eye(4%)had perforating injury. The two groups of patients were followed-up for 6 mo after surgery, and the treatment effects were compared.RESULTS:There was no statistically significant difference in visual acuity between the two groups of patients before vitrectomy(P>0.05). In the treatment group A, 10 eyes(31%)had significantly improved visual acuity, 21 eyes(66%)had effectively enhanced visual acuity, and 1 eye(3%)had no improvement in visual acuity at 6 mo after surgery. Among the 28 eyes in the treatment group B, 5 eyes(18%)had significantly improved vision, 16 eyes(57%)had effectively enhanced vision, and 7 eyes(25%)had no change in vision, with statistically significant difference between the two groups(U=322.5, P=0.032). There was no significant difference between the treatment group A and the treatment group B in complications such as secondary glaucoma, silicone oil dependence, vitreous hemorrhage, and eyeball atrophy(P>0.05). There was no evidence of traumatic proliferative vitreoretinopathy(TPVR)in the treatment group A during postoperative follow-up, which was significantly lower than that of the treatment group B(P<0.05).CONCLUSION:The prognosis of the stage Ⅱ vitrectomy for open ocular injury is relatively good after completing the stage Ⅰ surgery within 2 wk.
