Abstract

We reviewed 49 patients(50 eyes) who had undergone pars plana vitrectomy for the traumatized eyes during the last 4 years. We divided patients into 4 groups according to the characteristics of ocular injuries-anterior segment Injury, posterior penetrating injury, intraocular foreign body and blunt injury. We analyzed surgical results and compared surgical outcomes according to timing of vitrectomy performed(within 2 weeks VS more than 2 weeks after trauma). Anatomical success was achieved in 36 eyes(72.0%) and functional success was achieved in 23 eyes(46.0%). The main causes of functional and anatomical failure were macular pucker and phthisis bulbi respectively. The anatomical and functional success rates were higher when vitrectomy was performed within 2 weeks after trauma. In posterior penetrating injury group, however, anatomical success rate was lower when vitrectomy was performed more than 2 weeks after trauma. The frequency of retinal detachment was higher when vitrectomy was performed more than 2 weeks after trauma. In cases of intraocular foreign body, retinal detachments were developed in all patients after vitrectomy performed more than 2 weeks after trauma. If vitrectomy is required for patients with ocular injury, we suggest vitrectomy within 2 weeks after frauma for better chance to perserve the globe and for salvaging vision.
