Background: the recent progress achieved in posterior vitrectomy and the use of silicon oil have resulted in an increase in the success rate of reattaching the retina in tractional retinal detachment.
The success rate improved from 65% to 97%;however, this was not accompanied by a commensurate improvement in visual acuity among those patients Objective: to study anatomical and visual outcomes of posterior vitrectomy in diabetic patients and factors that influence them
Methods: the study involved 67 eyes of 61 diabetic patients that underwent posterior vitrectomy for the treatment of:  dense vitreous hemorrhage without a macula-threatening retinal detachment 34 eyes [50.7%] , or  tractional retinal detachment which threatened or involved the fovea with or without vitreous hemorrhage 33 eyes [49.3%] . All patients were observed for 6 months after surgery Results: complete reattachment of the retina was achieved in 43 eyes [82.7%] over an observation time of 6 months;however the visual acuity improved only in 40 eyes [59.7%] , did not change in 13 eyes [19.4%] , and deteriorated in 14 eyes [20.9%]
Conclusion: the condition of the macula, the extent to which the fibro vascular tissue was attached to the retina, the type of tamponade used in phakic eyes, the extent of retinal perfusion, and perioperative complications played an important role in defining the anatomic and visual results of the surgery
