title: Anterior chamber migration of dexamethasone intravitreal implant (Ozurdex®) through basal iridectomy (Ando) in a pseudophakic patient.
abstract: OBJECTIVE
  Intravitreal implantation of dexamethasone implant (Ozurdex®) is being widely used for the treatment of macular edema (ME) after branch or central retinal vein occlusion, diabetic ME, and persistent ME associated with uveitis or Irvine-Gass syndrome. We describe a complication: migration of the dexamethasone implant into the anterior chamber through basal iridectomy (Ando) in a pseudophakic patient with development of corneal edema and secondary high intraocular pressure.
  
  
  METHODS
  This is a case report of migration of Ozurdex® through basal iridectomy in a pseudophakic patient with iris claw lens.
  
  
  CONCLUSIONS
  Pseudophakic patients, with a history of vitrectomy, even those with a basal iridectomy (Ando), are at high risk for migration of the Ozurdex® into the anterior chamber and development of corneal edema.
