Anterior chamber migration of a dexamethasone implant in a pseudophakic patient with a scleral-fixated posterior chamber intraocular lens

We report the case of anterior chamber migration of a dexamethasone implant (Ozurdex (R)) in a 54-year-old woman with macular edema due to a central retinal vein occlusion. The patient had undergone complicated cataract surgery 5 years previously with a scleral-fixated posterior chamber lens implant. An uneventful intravitreal Ozurdex (R) implant injection was performed. One month later, the patient presented emergently with painless visual loss. Slit-lamp examination revealed the presence of discrete corneal edema associated with the implant in the anterior chamber. The implant was surgically removed from the anterior chamber 24 hours later with complete resolution of corneal edema. (C) 2013 Elsevier Masson SAS. All rights reserved.
