Distichiasis
Distichiasis is the abnormal growth of an eyelash from the meibomian
glands along the eyelid margin. This positions them directly out of the
lid margin and they contact the eye surface due to this. The harm this
causes depends on the stiffness of the eyelash that grows, the number of
them and their exact position. This condition is most common in cocker
spaniels, Chesapeake Bay retrievers, Lhasa apsos, miniature poodles, golden
retrievers, shelties, and shih tzus.
Untreated, distichiasis can lead to corneal ulcers, chronic eye pain,
excessive tearing, and eyelid spasms. It is almost certainly uncomfortable
for the dog and permanent removal of the offending eyelashes is best when
any clinical signs are present.
Surgery is done in a number of ways, depending on the number of lashes
present and the preferences of the surgeon. Cryosurgery (freezing of the
lid margin at the affected sites) can sometimes be done with a local anesthetic
in a cooperative dog. There are other surgical options. Almost any surgery
for this condition should be done with an operating microscope or good
magnification so many general practitioners refer these cases to veterinary ophthalmologists.
Postoperative care of inflammation from the surgery is usually necessary
and should be planned for. There are usually two or three follow-up visits
to check for regrowth of the eyelashes and removal of any that return or
persist. In most cases, this can be treated with success. This makes life
much more comfortable for your dog.
