Objective: The authors describe a localized probable immunoreaction after repeated transplantation of amniotic membrane (AM) onto the corneal surface.
Design: Interventional case report.
Intervention: 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.
