Abstract:
Objective:To observe and preliminarily analyze the risk factors related to silicone oil dependence after pars plana vitrectomy (PPV) in open globe injuries (OGI) .Methods:A retrospective clinical study. This study included 211 patients with OGI who received PPV treatment from January 1, 2005 to December 31, 2016 in Eye Injury Vitrectomy Study database. Silicone oil dependence was defined as the intraocular pressure <10 mm Hg (1 mm Hg= 0.133 kPa) in silicone oil tamponade eye 6 months after PPV. The patient's age, intraocular pressure, type of injury, length of eyeball wound, as well as the presence of ciliary body injury, choroidal injury, and retinal resection and/or defect area were recorded in detail. Logistic multifactorial regression analyzed the correlation between age, eye wound length and ciliary body iinjury, choroidal injury and retinal resection and/or defect severity and silicone oil dependence.Results:211 OGI eyes underwent vitrectomy were included, the mean age of the study population was 32.93 years (range 1-73 years), and the median follow-up period was 20.06 months (range 5.85-90.58 months). Among the 211 eyes, 121 (57.3%, 121/211), 52 (24.6%, 52/211), 23 (10.9%, 23/211) and 15 (7.1%, 15/211) were rupture, perforation, intraocular foreign bodies and penetrating injury, respectively. 98 eyes (46.4%, 98/211) of silicone oil dependence in total, among them, 64 (65.3%, 64/98), 19 (19.4%, 19/98), 9 (9.2%, 9/98) and 6 (6.1%, 6/98) eyes were rupture, perforation, intraocular foreign body and penetrating injury, respectively. Correlation analysis revealed that silicone oil dependence was significantly associated with ciliary body injury [odds ratio ( OR) = 2.150, 95% confidence interval ( CI) 1.052-4.393], choroidal injury ( OR=3.233, 95% CI 1.454-7.191), and retinal injury ( OR=2.731, 95% CI 1.393-5.353). No correlation was found with age ( OR= 0.981, 95% CI 0.960-1.002) or ocular wound length ( OR=1.716, 95% CI 0.987-2.984) ( P> 0.05). Conclusion:Silicone oil dependency following PPV in OGIs are associated with ciliary body, choroidal, and retinal injuries, but no association with age or length of the ocular wound.
