Distichia are abnormal eyelashes that exit through the eyelid margin. These abnormal hairs are common in the Cavalier King Charles Spaniel, Bulldog, Shih Tzu, Cocker Spaniel, Golden Retriever, Havanese, and many other breeds. In most dogs, distichia are an incidental finding and they do not cause any ocular problems. However, in some dogs that have numerous distichia or very stout distichia they can cause surface irritation leading to squinting and excessive tearing. Surgery is indicated in these, affected dogs. The surgery of choice involves two procedures: electroepilation followed by cryosurgery.
