Is my dog's eye running from new hairs after eyelid surgery?
Hi, thanks for using PetCoach! Poor Buddy he has been through a lot!
A dermoid cyst is normal tissue located on an abnormal spot, on the eye is tends to be hair that grows on the surface of the eye. The dermoid cyst is removed via a keratectomy. That is usually curative. I think what your vet says Buddy has now are ectopic cilia, which are tiny hairs that have grown in an abnormal location and are irritating his eye causing pain. They can cause excessive tearing, blinking and can even scratch the cornea (surface of the eye). Another possibility is distichia. Distichia are abnormal rows of eyelashes that, due to abnormal conformation, rub against the cornea.
If Buddy has symptoms the hairs should be removed. Electrolysis or cryosurgery is used to remove the offending hairs and is done at an Veterinary ophthalmologist.
I hope this helps and I wish Buddy the very best!
