Canine autologous platelet rich fibrin membrane transplantation for corneal reconstruction after the excision of dermoid cyst in two pups

Two Rottweiler puppies were presented to the University Veterinary Hospital, Kokkalai, KVASU, with the history of epiphora from the right eye for a period of three weeks. On ophthalmic examination, a dermoid cyst could be observed at the lateral border of the right cornea in both the dogs. Dermoid cysts were excised under general anaesthesia by superficial keratectomy followed by conjunctivectomy. Autologous platelet rich fibrin membrane (PRFM) was transplanted over the wound bed by suturing onto the bulbar conjunctiva followed by third eyelid membranoplasty. After the transplant, the corneal epithelisation process took place over two weeks. The cornea returned to normal transparency after five weeks. At eight weeks following the transplant, the dog had little neovascularisation and slight corneal scarring. In conclusion, canine autologous PRFM transplantation can aid corneal healing following the removal of dermoid cysts in dogs.
