Purpose: To determine the preoperative characteristics that predict the success of vitreous surgery in eyes with diabetic maculopathy. Methods: Sixty–three eyes of 41 cases that underwent vitreous surgery for diabetic maculopathy and were followed for more than 12 months at the Juntendo University Urayasu Hospital, were studied. The clinical characteristics evaluated were the visual acuity and the retinal thickness measured by optical coherence tomography (OCT). The visual acuity and retinal thickness before surgery were compared to that at 12 months after surgery. Patients were divided into those that had or did not have a posterior vitreous detachment (PVD), by the type of macular edema, the level of HbA1c, and visual acuity before surgery. Results: Statistically, the visual acuity and retinal thickness recovered 12 months after surgery in all eyes. Prognosis was better in patients who had a PVD than those that did not have a PVD. At 12 months, the improvement of visual acuity and reduction of retinal thickness were not related to the type of macular edema, level of PVD, and visual acuity before surgery. Conclusions: Vitreous surgery was effective irrespective of the type of macular edema, level of PVD, and retinal function.
