title: Bevacizumab (Avastin) for diabetic macular edema in previously vitrectomized eyes.
abstract: OBJECTIVE
  To report the visual acuity (VA) and foveal thickness (FT) changes after intravitreal bevacizumab for diabetic macular edema (DME) in previously vitrectomized eyes.
  
  
  METHODS
  Retrospective, noncomparative, interventional case series.
  
  
  METHODS
  Medical records of 11 eyes of 10 patients who underwent intravitreal bevacizumab injection for persistent DME were reviewed. This retrospective study included eyes that had persistent DME despite prior pars plana vitrectomy with internal limiting membrane removal at our institution with optical coherence tomography (OCT) assessment of DME. All eyes received three intravitreal injections of bevacizumab 1.25 mg/0.05 ml monthly.
  
  
  RESULTS
  Mean FT was 408 +/- 77 microm at baseline, 453 +/- 97 microm at three months, and 454 +/- 101 microm at six months (P = .172). Mean Early Treatment Diabetic Retinopathy Study (ETDRS) letter scores were 59 +/- 15 (20/80) at baseline, 59 +/- 16 (20/80) at three months, 57 +/- 15 (20/80) at six months (P = .398).
  
  
  CONCLUSIONS
  No change in VA and FT was observed in the short-term after intravitreal bevacizumab for DME in previously vitrectomized eyes.
