Purpose: Amniotic membrane has been consolidated as an useful adjunct in the treatment of ocular surface disorders. Its use is based on the ability to improve epithelial healing and to decrease inflammatory, angiogenic and cicatricial processes. The purpose of this study was to report the surgical outcome of human amniotic membrane use for surface reconstruction in ocular cicatricial diseases. Methods: Amniotic membrane was obtained at the time of cesarean section and was preserved at -80ºC in glycerol and cornea culture media at a ratio of 1:1. Eleven eyes of 10 patients underwent amniotic membrane transplantation, associated (8 eyes) or not (3 eyes) with corneal limbal graft. Ocular surface reconstruction was performed after chemical burns (6 eyes), trauma (1 eye) and Stevens-Johnson's syndrome (SJS) (4 eyes). Results: Mean follow-up time was 5.22 months (range, 2-13 months). One case of SSJ developed early postoperative infection and was excluded from the analysis. Successful ocular surface reconstruction was achieved in 8 eyes (80%). Surgical failure was observed in 2 cases of SJS who presented corneal melting at the time of surgery (20%). Conclusions: This study suggests that amniotic membrane transplantation is an effective alternative for surface reconstruction in stable ocular cicatricial diseases. Larger studies with longer follow-up are necessary to further analyse this procedure.
