Purpose:
To present a case of chemical injury and a case of thermal injury treated by amniotic membrane transplantation in acute phase.
Methods:
Case reports. An eye with sodium hydroxide injury, opaque cornea, and limbal ischemia of more than 180 degrees and an eye with hot tea injury, opaque cornea, stromal edema, and scarring were treated by amniotic membrane transplantation within the first few weeks of injury.
Results:
In the eye with sodium hydroxide injury, 4 months after amniotic membrane transplantation, the ocular surface is stable, superficial corneal scarring with vascularization is present, and visual acuity is 20/25. In the eye with thermal injury, 6 months after amniotic membrane transplantation, the ocular surface is stable, but there is superficial scarring and vascularization, and visual acuity is 20/20.
Conclusions:
Amniotic membrane transplantation can be considered in chemical injury with severe limbal ischemia and in severe thermal injury in acute phase. Long-term studies are warranted to evaluate further the efficacy of amniotic membrane transplantation in these clinical situations.
