Abstract
Purpose: This study evaluated the outcome of severely injured eyes treated with early primary vitrectomy with silicone oil filling. Methods: A total of 435 eye injuries, which required surgical intervention, were reviewed retrospectively. In 13 eyes (3%) pars plana vitrectomy and silicone oil filling were performed as primary surgical repair. Silicone oil filling was restricted to cases with laceration of the retina larger than 4 disc diameters (nine eyes), primary retinal detachment larger than two quadrants (two eyes) and/or persistent intrasurgical hemorrhage (12 eyes). All patients underwent surgery within 24 hours. Results: After a mean follow-up period of 28.7 months (range, 9-70 months), 11 eyes achieved a visual acuity ranging from 20/25 to 20/200. Silicone oil was removed in 11 of 13 eyes after 5.8 ± 4.6 months. Recurrent proliferative vitreoretinopathy developed in two eyes. Conclusions: Silicone oil tamponade after early primary pars plana vitrectomy may be an alternative for primary repair after trauma, especially in severely injured eyes with retinal lacerations larger than 4 disc diameters, persistent intrasurgical bleeding, and/or primary retinal detachments.
