Abnormal overflow of tears from eyes is denoted as Epiphora. The cause can be distichiasis – turning in of the eyelashes or entropian – turning in of the eyelid. The disease is congenital and can occur in many breeds. Young shelties, shih tzus, Lhasa apsos, cocker spaniels, pekingese, bulldogs, dachshunds, and miniature poodles are most commonly affected with distichia. Entropion is most commonly seen in some Chinese shar peis, pugs, mastiffs, poodles, Labrador retrievers and chow chows. The upper or lower lid may be affected. This condition may occur secondary to eye irritation.
Common signs of epiphora are overflow of tears, tear drainage and/or staining on face. Other signs include:
Squinting
Inflammation
Redness and irritation
Discharge from eye
Ulcers of the cornea
Skin around eye is loose or sagging
