title: Fast Resolution of Recurrent Pronounced Macular Edema following Intravitreal Injection of Dexamethasone 0.7 mg.
abstract: OBJECTIVE
  To report the fast resolution of recurrent pronounced macular edema due to central retinal vein occlusion (CRVO) within 72 h following intravitreal injection of dexamethasone 0.7 mg (Ozurdex®).
  
  
  METHODS
  An interventional case report with optical coherence tomography scans and fluorescein angiographic pictures.
  
  
  RESULTS
  A 69-year-old Caucasian man underwent intravitreal injection of dexamethasone 0.7 mg due to incomplete CRVO. He had previously undergone 6 intravitreal injections of bevacizumab 1.25 mg (Avastin®) and a C-grid laser photocoagulation over an interval of 16 months. After repeated recurrences of macular edema, the injection of dexamethasone reduced the macular edema from 570 μm preoperatively to 246 μm postoperatively within 72 h following the injection. Best-corrected visual acuity improved from 0.1 to 0.6 within the same interval.
  
  
  CONCLUSIONS
  Dexamethasone can lead to a very fast reduction of macular edema in patients with vision loss due to CRVO and may facilitate an immediate visual rehabilitation. Retinal anatomy and visual acuity may be restored even in long-standing, recurrent cases.
