Corneal stromal sequestration in a dog.
A case of corneal sequestrum in a 9-year-old Shih Tzu is reported. On the ophthalmic examination a brown-pigmented ulcer with mild edema and corneal vascularization was present. The brownish plaque was facing an inferior palpebral tumor. A superficial keratectomy followed by a grid keratotomy and removal of the palpebral mass were performed. Histological findings revealed an inflammatory cell i...
متن کاملUltrastructural findings in feline corneal sequestra.
OBJECTIVES (1) To describe the ultrastructural features of corneal sequestra in cats; and (2) to enhance our understanding regarding the pathogenesis of feline corneal sequestration. METHODS Nine corneal sequestra were harvested via keratectomy from globes of nine cats. The sequestra were routinely fixed then postfixed for high resolution light and transmission electron microscopy (HR-LM and ...
متن کاملLamellar keratoplasty for the treatment of feline corneal sequestrum.
A lamellar keratoplasty was used to treat corneal sequestrum in four Persian cats (six eyes). Following a superficial keratectomy, lamellar corneal allografts (feline corneal tissue) or heterografts (canine corneal tissue) which had been preserved at -20 degrees C were placed in the recipient cornea. All grafts became optically transparent within 2 months following surgery and no recurrences of...
متن کاملTransplantation of a tissue-engineered corneal endothelium reconstructed on a devitalized carrier in the feline model.
PURPOSE To evaluate the functional outcome of tissue-engineered corneal endothelium reconstructed on a devitalized carrier and transplanted in the living feline model. METHODS Eighteen healthy adult cats underwent full-thickness corneal transplantation. In 11 animals, the donor cornea was reconstructed from cultured allogeneic feline corneal endothelial cells seeded on the denuded Descemet's ...
متن کاملIn Vivo Functionality of a Corneal Endothelium Transplanted by Cell-Injection Therapy in a Feline Model
PURPOSE To evaluate the functionality of a corneal endothelium reconstituted by injection of corneal endothelial cells (CEC) in the anterior chamber of a feline model. METHODS We operated the right eyes of 16 animals. Eight underwent central endothelial scraping and injection with 2 × 10(5) (n = 4) or 1 × 10(6) (n = 4) feline CEC supplemented with Y-27632 and labeled with 3,3'-Dioctadecyl-5,5...
