Objective: To evaluate the clinical manifestations and surgical prognosis of macular tractional retinoschisis in proliferative diabetic retinopathy. Design: Retrospective case series. Participants: Cases with macular tractional retinoschisis with or without combined traction detachment (TRD) in proliferative diabetic retinopathy confirmed by optical coherence tomography (OCT) at a single institution between January 2007 and August 2010. Methods: Cases were divided into two groups. Group A had tractional retinoschisis only while Group B had TRD with retinoschisis of the elevated retina. Clinical data including OCT findings were recorded and analyzed. Main Outcome Measures: Demographic data, clinical pictures, surgical results, and OCT findings will be compared between two the groups.
