DISTICHIASIS IN SHIH TZU
Distichiasis describes a condition in which eyelashes are abnormally located in the eyelid margin. This condition may occur at any time in the life of a dog and is probably inherited in many breeds.
Clinical signs of distichiasis include tearing (in varying amounts), redness of the conjuctiva, and inflammation and possible ulceration of the cornea. Diagnosis can be made by your veterinarian.
Treatment of distichiasis includes epilation, electro-epilation, cyrotherapy, or surgical excision. Each procedure can offer an effective treatment regimen for canine distichiasis.
In Shih Tzu, distichiasis occurs with reasonable frequency and, in some dogs with shallow orbits, produces chronic inflammation of the cornea. Most dogs are only mildly affected. The hereditary basis has not been established, although it seems probable due to the high incidence in some breeds. Breeding discretion is advised; reducing the incidence of distichiasis is a logical goal.
