title: Hypopyon after repeated transplantation of human amniotic membrane onto the corneal surface.
abstract: OBJECTIVE
  The authors describe a localized probable immunoreaction after repeated transplantation of amniotic membrane (AM) onto the corneal surface.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  Amniotic membrane was transplanted onto the corneal surface of a 78-year-old female with a deep trophic corneal ulcer resulting in temporary epithelial closure. A second and finally third amniotic membrane transplantation (AMT) was performed because of recurrent ulcerations. All three AMs were obtained from the same donor.
  
  
  RESULTS
  The first transplantation of the AM was without complication. However, a hypopyon developed 2 days after the second and 2 days after the third AMT, but the patient responded immediately to topical and systemic corticosteroids.
  
  
  CONCLUSIONS
  Immunologic, toxic, and hypersensitivity effects could have contributed to the hypopyon iritis that appeared after the second and third AMT, but not after the initial transplantation. In case of a repeated AMT, the use of AM from different donors may help to minimize the risk of an immediate postoperative intraocular inflammation.
