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 anaesthetic 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.
