Vitrectomy for diabetic traction retinal detachment using the multiport illumination system

OBJECTIVE: To examine the visual and anatomic results of bimanual vitrectomy surgery with the multiport illumination system (MIS) in eyes with advanced diabetic traction retinal detachment. DESIGN: Retrospective, noncomparative interventional case series. PARTICIPANTS: Sixty-seven consecutive eyes in 62 patients having vitrectomy with the MIS. METHODS: During surgery, the vitreous, the posterior hyaloid membrane, and fibrovascular proliferative tissue were removed by using bimanual dissection made possible by the MIS. MAIN OUTCOME MEASURES: Retinal reattachment rate, visual function, and postoperative complications were compared with previously published series of vitrectomy for diabetic traction retinal detachment. RESULTS: With a minimum of 6 months of follow-up, complete retinal reattachment was achieved in 62 eyes (93%), and macular attachment was achieved in all 67 eyes. Vision was stabilized or improved in 51 eyes (72%), and 5/200 vision was achieved in 47 eyes (70%). No unique complications, such as incision-related retinal tears, occurred. CONCLUSION: MIS allows bimanual surgery during vitrectomy for diabetic traction retinal detachment, with good visual and anatomic results.
