Non-contact wide-angle viewing system assisted vitreoretinal surgery for severe ocular trauma

Abstract

Objective To investigate the clinical efficacy of vitreoretinal surgery under non-contact wide-angle viewing system for severe ocular trauma. Methods The data of 36 eyes of 36 patients with severe ocular trauma treated by vitreoretinal surgery under non-contact wide-angle viewing system from June 2013 to September 2014 were retrospectively analyzed. Results The eye condition of these patients was complex and the injury in multiple tissues coexisted. The successful rate of the extraction of intraocular foreign bodies from 15 eyes was 100%. After the surgery, there were 26 eyes with vitreous hemorrhage and 5 eyes with suprachoroidal hemorrhage. The rate of reattachment in 20 eyes with retinal detachment was 85.00%. Suppurative endophthalmitis in 8 eyes was well controlled. The postoperative visual acuity improved in 26 eyes (72.22%), unchanged in 6 eyes (16.67%) and decreased in 4 eyes (11.11%). Conclusion The non-contact wide-angle viewing system can provide wide visual field for the vitreoretinal surgery in treating severe ocular trauma, decrease the influence of the ocular refractive media opacity and simplify the operative procedure.
