GENERAL DESCRIPTION

Epiphora is the term used to describe excessive tearing which leaves staining around the eyes and on the face.

SOURCE & CAUSE(S)

Epiphora occurs because a mechanism is causing the production of too many tears.  There are several sources for why this condition occurs and they include the following:

  • Entropion (abnormal shaped eyelash(s))
  • Obstruction of the tear ducts
  • Malposition of the tear ducts in dogs with protruding eyes

Certain breeds are more likely to develop Epiphora. These breeds include the Cocker Spaniel, Lhasa apso, Yorkshire terrier, English Bulldogs, Shar Peis, and Boston Terriers.

SIGNS & SYMPTOMS

The most obvious symptom noted is tear staining on the face and constant wetness around the eyes.

DIAGNOSIS & TESTS

Diagnosis begins with a complete history and a physical exam.  Your veterinarian will be most likely do the following:

    • Schirmer tear test- This is the most common tear producing test performed.  A special strip of absorbent paper is placed inside the lower eyelid and left for about a minute, during which time the amount of tear production is measured.  As tears are produced the strip changes color allowing for easy measuring.  

    • Corneal stain-a fluorescent dye is placed in the eye and then examined with an ultraviolet light.  If an ulcer is present it will glow green under the UV light.  Your veterinarian can now evaluate size and location of ulcer.

    • Intraocular pressure (IOP) - This can be measured to determine if glaucoma is present.

    • Tear duct exam- the tear ducts are examined and sometimes flushed to ensure proper drainage is possible.

TREATMENT & MANAGEMENT

The treatment of Epiphora can be done using topical medications, antibiotics if an infection is present, and sometimes through surgical repair of the tear ducts or the eye lashes if they are the chief cause.  Managing Epiphora is done through daily cleaning of the tear stained areas.

PREVENTION & HELPFUL TIPS

There is no prevention for excessive tearing.
