Canine amniotic membrane transplantation for corneal reconstruction after the excision of dermoids in dogs.

Transplantation of canine amniotic membrane (AM) in conjunction with a third eyelid flap was performed after the removal of large dermoids by keratectomy and conjunctivectomy on 7 eyes of 7 dogs. Corneal epithelialization was completed within 2 weeks after the transplantation. Five eyes attained normal transparency of the cornea within 5 weeks. Slight pigmentation of the bulbar conjunctiva at the limbus was observed in 1 dog that had pre-existing pigmentary keratitis. Neovascularization and scarring of the cornea and impaired vision were not found in any dogs at 8 weeks after the transplantation. In conclusion, transplantation of canine AM can promote corneal healing after the excision of large dermoids in dogs.
