Causes
Growth of eyelashes from an abnormal location on the eyelid. There is a hereditary component in several breeds (Cocker Spaniel, Bulldog, Poodle).
Diagnosis
Ophthalmic examination under magnification to locate the abnormal eyelashes.
Treatment
If they cause no discomfort, monitoring only. If they damage the eye: epilation, electroepilation or cryotherapy to remove the eyelashes at the root.
Prevention
Selection in breeding to reduce the predisposition.
