title: Human amniotic membrane in the reconstruction of the ocular surface.
abstract: We sought to determine the efficacy of amniotic membrane transplantation (AMT) in the reconstruction of ocular surface. AMT was performed on 40 eyes with following indications: I, persistent corneal ulceration (n = 12); II, impending perforation (n = 6); III, persistent epithelial defect on the corneal graft (n = 6); IV, recurrent pterygia (n = 10), and V, risk of conjunctival scarring (n = 6). Amniotic membrane was prepared from a fresh placenta under sterile conditions, washed with BSS containing penicillin, streptomycin, neomycin and amphotericin B and stored at -80 degrees C in 1:1 InoSol:Glycerol solution. Donor serological test for HIV, HBV and HCV were all negative. Associated surgical procedures according to indication were performed. Healing of the corneal ulcer in Group I was obtained in 67% of eyes at 1-3 weeks after surgery, Group II: AMT was followed by 'a chaud' keratoplasty in 33% and by planned keratoplasty in 67% patients, Group III: healing of the defect in 33% of eyes in 2-5 postoperative weeks, Group IV: no recurrence of pterygium ingrowth in 70% in the follow up period of 6-14 months, and V: 84% of patients had good eye motility without any synechia formation. We concluded that AMT have shown to be effective in enhancing healing of the corneal defects, in prevention of symblepharon formation and recurrent pterygium ingrowth. In case of impending perforation, AMT alone was not a method of treatment but is useful as a first step procedure in preparing the eye for the corneal transplantation.
