Oh, Kwon, and Kim: Five-Layered Reinforcing Amniotic Membrane Transplantation for Treatment of Deep Corneal Ulcer or Perforation

Abstract

Purpose

To evaluate the efficacy of five-layered reinforced amniotic membrane (AM) transplantation for treating deep corneal ulcer or perforation.

Case summary

We performed a five-layered reinforced AM transplant in three cases of corneal ulceration or perforation using mechanical compressed lyophilized AMs. In all cases, the perforated cornea healed with reepithelization within 2 weeks and the ocular surface was stabilized for more than 1 year.

Conclusions

Five-layered reinforced AM transplantation may be an alternative method for treating deep corneal ulcers or perforations.

Case 1 (A) Initial photographs. The cornea was perforated and the anterior chamber was shallow. (B) Anterior chamber was well formed and no epithelial defects were seen 18 months after 5-layered reinforcing AM trasplantation. Case 2 (C) Initial photographs. Corneal ulcer (2 × 3 mm) with peripheral opacity was seen preoperatively. (D) The ocular surface was stabilized until postoperative 5 months. Case 3 (E) Initial photographs. Corneal ulcer (5 × 5 mm) and total limbal deficiency with neovascularization were seen. (F) To prevent complication of exposure keratitis, tarsorrhaphy has been maintained until post operative 15 months.
