A '''Dermoid''' is defined as a congenital circumscribed growth of microscopically normal tissue in abnormal place. They can involve a variety of structures in the eye, including the cornea.
==Signalment==
Believed to be inherited in '''St Bernards''', '''Dalmatians''' and '''Dachshunds''' dogs and '''Birman''' and '''Burmese''' cats.
==Clinical Signs==
If the Dermoid contains hair growing tissue, the hair can cause irritation of the cornea and conjunctiva leading to corneal opacity, conjunctival hyperaemia and ocular discharge.
==Diagnosis==
Apparent on clinical examinations of young animals.
==Treatment==
Dermoids only grow slowly, if at all, so consideration may be given to monitoring if not causing any clinical signs. Resolution requires '''surgical excision'''. The cornea is often thinner under a Dermoid so referral to an opthalmologist may be wise.
==Control==
As believed to be inherited, do not breed from affected animals.
