Abstract: Objective To investigate the differences between improved membrane dissection and bimanual enbloc excision in 23G vitrectomy in the treatment of proliferative diabetic retinopathy(PDR). Method A total of 38 PDR patients(41 eyes) undergoing vitrectomy from Jun 2013 to Jan 2014 was enrolled in this study. The patients were randomly divided into bimanual enbloc excision group(19 patients, 20 eyes) and improved membrane dissection group(19 patients, 21 eyes). After the procedures, number of iaogenic holes, ratio of silicon oil fill, operation time, postoperative hemorrhage, and postoperative proliferative membrane were observed. Result Improved membrane dissection decreased the number of iaogenic holes,ratio of silicon oil fill,without increasing the operation time, incidence of postoperative hemorrhage, or proliferative membrane aggravation. Meanwhile, visual function recovery wasn't influnced. Conclusion The improved membrane dissection is better in 23G vitrectomy to treat proliferative diabetic retinopathy(PDR).

Key words: Proliferative diabetic retinopathy, Enbloc excision, Membrane dissection, 23G vitrectomy
