RECONSTRUCTION OF ANTERIOR EYE SEGMENT AFTER CHEMICAL BURN

Purpose. The authors evaluate the efficacy of the amniotic membrane transplantation in complicated wounds of the anterior eye segment which can not be successfully treated by corneal transplantation alone. Methods. Ten years old child had chemical burn of the entire anterior eye segment, resulting in symblepharon formation, corneal conjunctivalization and cataract formation. Injured eye underwent following surgeries: extracapsular cataract extraction, IOL implantation and keratoplasty. At the end of the surgery, amniotic membrane was placed to cover the entire anterior segment in order to prevent reformation of symblepharon and graft rejection. Patient was followed up for 4 postoperative months. Amnitoc membrane was prepared and stored in Lions Croatian Eye Bank. Results. The authors present anterior segment reconstruction together with postoperative appearance of the combusted eye. Placement of the amniotic membrane prevented symblepharon formation. By its action as mechanical cover and as actively secreting tissue (antiangiogenic factors) amniotic membrane enabled the corneal graft to retain its epithelialized surface. Conclusion. Amniotic membrane showed to be a successful barrier to reformation of symblepharon and enabled corneal graft survival in high-risk patient that have had chemical burn.
