Purpose: To evaluate vitrectomy for diabetic macular edema (DME) in eyes with at least moderate vision loss and vitreomacular traction.
Design: Prospective cohort study.
Participants: The primary cohort included 87 eyes with DME and vitreomacular traction based on investigator’s evaluation, visual acuity 20/63–20/400, optical coherence tomography (OCT) central subfield 300 microns and no concomitant cataract extraction at the time of vitrectomy.
Methods: Surgery was performed according to the investigator’s usual routine. Follow-up visits were performed after 3 months, 6 months (primary end point), and 1 year.
Main Outcome Measures: Visual acuity, OCT retinal thickening, and operative complications.Conclusions: After vitrectomy performed for DME and vitreomacular traction, retinal thickening was reduced in most eyes. Between 28% and 49% of eyes with characteristics similar to those included in this study are likely to have improvement of visual acuity, whereas between 13% and 31% are likely to have worsening. The operative complication rate is low and similar to what has been reported for this procedure. These data provide estimates of surgical outcomes and serve as a reference for future studies that might consider vitrectomy for DME in eyes with at least moderate vision loss and vitreomacular traction.
