Abstract:
Objectives To describe and evaluate the use of equine amniotic membrane transplantation
after lamellar keratectomy for the treatment of corneal sequestrum in cats.
Methods Six cats (seven eyes) of various breed and ages with corneal sequestra were
treated surgically with lamellar keratectomy and amniotic membrane transplantation.
All the sequestra and a small piece of the amniotic membranes used for each surgery
were submitted for histopathologic examination.
Results Five of the seven eyes showed minimal level of scarring in the cornea and
good transparency. No recurrences of the sequestra have been noted during the
follow-up period (3–9 months). One eye had necrosis of the amniotic membrane
2 weeks after the surgery. The sequestrum of this eye showed a high level of bacterial
contamination on histopathology. Three months later the same cat developed a
descemetocele in the area where the necrotic amniotic membrane was rejected. A
second eye developed a perforation under the amniotic membrane two weeks after the
surgery. The sequestrum of this eye was deep and without vascularization.
Conclusion Amniotic membrane transplantation after lamellar keratectomy was a valid
procedure for surgical treatment of corneal sequestrum in cats. The procedure resulted
in excellent cosmesis and functional vision in five of seven eyes; although case selection
is important, particularly to exclude the very deep and non-vascularized sequestra.
