Transplantation of amniotic membrane and limbal autograft in the treatment of recurrent pterygium

We surgically treated recurrent pterygium in two eyes of two patients aged 63 and 67 years. Both eyes showed symblepharon and restricted abduction. After excising the pterygium and separating the symblepharon, the bared sclera was covered by preserved amniotic membrane. This area was further covered by a piece of bulbar conjunctiva from the same eye. The amnion was used, as the rationale, because of its antiinflammatory effect, inhibition of neovascularization and absence of antigenicity. There was no recurrence after surgery. The ocular motility became normalized. The present surgical approach was thus useful in treating recurrent pterygium.
