Zusammenfassung:The aim of this study was to evaluate the effects of canine amniotic membrane, previously preserved in glycerin, used as a patch on the repair of experimentally-made superficial corneal ulcers and to compare corneal epithelization between the treated and non-treated groups. Xenogeneic amniotic membranes were collected aseptically and preserved in 99% glycerin at room temperature. Each animal was anesthetized and submitted to superficial corneal keratectomy of the left eye. The treated group received a fragment of canine amniotic membrane as a patch, while the control group had no treatment. The treated group showed blepharospasm, ocular discharge and conjunctival congestion. The membrane accelerated corneal repair in the beginning of the process, however, it delayed its conclusion (p
