Amniotic membrane implant in the correction of deep corneal ulcers in canines and felines

Abstract

<em>Introduction</em>: Most defects of the corneal epithelium, such as ulcerative keratitis, do not respond to conventional treatment and they progress to stromal ulceration and imminent perforation. Among new therapeutic options to correct these corneal defects, there is the use of amniotic membrane and corneal plasties both surgical treatments seek a corneal reepithelialization and an adequate healing process when medical treatment has not been successful. <em>Objectives</em>: This work seeks to analyze updated studies concerning amniotic membrane implants for the solution of deep corneal ulcers in canines and felines, in order to define the therapeutic principles of amniotic membrane in ocular pathologies, determine a protocol for the preparation of amniotic membrane grafts, and serve as a basis for practical studies about corneal implants in canines and felines in Colombia. <em>Conclusions</em>: Based on the results obtained during the document review process and the surgical experience of the authors, it can be concluded that the use of amniotic membrane supports the growth of the ocular surface epithelium and facilitates the migration of epithelial cells, provides a barrier to infection, promotes revitalization, and ameliorates pain. Thanks to its unique characteristics, it is an excellent option in the treatment of corneal ulcers. In recent years, its effectiveness has been demonstrated in the treatment of ocular surface diseases, and is widely used in this type of pathologies.
