title: VITREOMACULAR TRACTION AFTER DEXAMETHASONE INTRAVITREAL IMPLANT (OZURDEX) INJECTION: THE EFFECT OF ANOMALOUS POSTERIOR VITREOUS DETACHMENT.
abstract: OBJECTIVE
  To describe an unusual macular complication after dexamethasone intravitreal implant (Ozurdex) injection.
  
  
  METHODS
  Case history and macular optical coherence tomography findings are described. The report describes a patient with proliferative diabetic retinopathy and vitreoschisis who received Ozurdex treatment for diabetic macular edema.
  
  
  RESULTS
  After Ozurdex injection, visual acuity worsened because of newly formed vitreomacular traction that was demonstrated on optical coherence tomography imaging. A mechanism is proposed by which the medication might have contributed to this outcome.
  
  
  CONCLUSIONS
  In this patient with vitreoschisis, a thickened posterior hyaloid membrane and traction developed after Ozurdex injection. The authors recommend careful evaluation of the macula before injection, particularly in diabetic patients with vitreoschisis.
