Abstract:Corneal dermoid cyst is a kind of abnormal skin like tissue that grows in the cornea, conjunctiva, and cornesclera of human or animal. It is found in both humans and animals, and is more common in animals, especially in cattle and dogs. Keratodermoid cysts can cause blepharospasm, increased eye secretions, conjunctivitis, keratitis and corneal ulcers, and severe cases can lead to corneal perforation and eyeball necrosis. Keratodermoid cysts of the eye are treated by keratectomy or conjunctival excision, removal of the keratodermoid cyst and symptomatic treatment.The following is a case of a juvenile fighting dog with right keratodermoid cyst received in March 2022.Superficial keratectomy was performed on the dog to remove the right keratodermoid cyst and cover the keratodermoid cyst with conjunctiva flap,and the postoperative recovery was satisfactory.
