Why Is My Dogs Tear Duct Swollen

The nasolacrimal system includes the lacrimal duct. The drainage of tears from the eye is made possible via the nasolacrimal system, which consists of several small tubes. Two tiny apertures in the eyelids, one on the upper and one on the lower, close to the nose, mark the beginning of the nasolacrimal duct. The bigger nasolacrimal duct, which connects these two smaller ducts, descends into the nasal passages. This system enables extra tears to exit the eye and flow into the mouth and nose.

This nasolacrimal duct can become blocked or occluded in some dogs. Tears may overflow and spill out of the eye due to obstruction. The excess tear production may cause dampness and tear stains beneath the eye. The most frequently impacted nasolacrimal duct is the lower one, and obstruction of the lower duct has more clinically obvious symptoms.

What are the possible causes of lacrimal duct obstruction?

The obstruction may occasionally be caused by the dog’s head and muzzle’s size and form. A congenital flaw in how the nasolacrimal duct is formed can potentially result in obstruction. Because of this flaw, there is no opening where the conjunctiva and nasolacrimal duct meet (pink tissue surrounding the eye). Imperforate puncta are what this is known as. Cocker Spaniels are frequently afflicted by this illness, however other breeds might also be.

Although other breeds may be affected, Cocker Spaniels are frequently impacted by this illness.

Lacrimal duct occlusion also occasionally appears after birth. Swelling that obstructs the duct might result from infection or inflammation within the eye or lacrimal duct. Foreign objects that become trapped inside the lacrimal duct or tumors that form along the duct can potentially obstruct the duct.

What are the clinical signs of a lacrimal duct obstruction?

Nasolacrimal duct obstruction symptoms are mostly aesthetic in nature. The majority of affected canines exhibit reddish tear stains on their faces or excessive eye watering. However, in persistent or severe cases, bacteria may start to form in the wet hair around the eyes. The presence of these germs may cause your dog’s face to start to smell bad. A skin infection beneath the eyes in dogs can also cause redness, itching, swelling, and/or hair loss.

How is a lacrimal duct obstruction diagnosed?

The dye fluorescein is frequently used in the diagnosis of nasolacrimal duct blockage. With this dye, even minute amounts of dye can be seen by your veterinarian since it fluoresces (glows) under a black light. The dye is injected into the eyes several times; from there, it should pass through the nasolacrimal duct and appear in the mouth and nose. Within 5 to 10 minutes after delivery, if the dye has not entered the nasal cavity, this may indicate a nasolacrimal duct obstruction.

When a patient is sedated, the veterinarian may use magnification to check the eye to see if a duct opening is present. If this aperture can be seen, saline solution can be flushed into the nasolacrimal duct by inserting a cannula (thin tube) into the orifice. This may be sufficient to remove minor obstructions, but it can also help the veterinarian identify more serious impediments.

“Depending on your pet’s condition, your veterinarian may additionally advise a bacterial culture to determine infection or other testing.”

Additional diagnostic tests could be advised in specific circumstances. Imaging examinations like X-rays, CT scans, or MRIs may be part of these procedures to rule out malignancies that could cause obstruction. Depending on your pet’s condition, your veterinarian may additionally advise a bacterial culture to detect infection or other testing.

How is a lacrimal duct obstruction treated?

Anti-inflammatory drugs and antibiotics may help to relieve nasolacrimal duct obstruction brought on by inflammation. To increase the likelihood that your dog’s lacrimal duct obstruction will be resolved, take all prescribed meds as directed by your veterinarian and attend all planned rechecks.

Surgery may be needed for treatment in other circumstances. Surgery can be done to remove foreign objects from the duct, widen the duct’s entrance, and remove tumors that are squeezing it. A stent may be implanted to permit passage via the lacrimal duct in more serious situations.

What happens if a lacrimal duct obstruction is not treated?

Nasolacrimal duct obstruction will continue to affect tear staining if untreated. Due to excessive wetness, dogs that are not treated are also more likely to get skin infections around their eyes.

Why is my dog’s eye corner swollen?

According to Vygantas, early cherry eye in dogs is pretty simple to identify. She explains that a fleshy pink bulge in the corner of the eye is a telltale sign of cherry eye or protrusion of the tear gland of the third eyelid.

In order to prevent your dog from moving during the flushing treatment, they will be put under general anesthesia or sedated. If general anesthesia is necessary, you must fast your dog for at least eight hours before the procedure. To find the obstruction and decide whether surgical intervention is necessary or if flushing is likely to eliminate the obstruction, a dye may be injected into the eye and radiographs taken prior to the surgery. The first course of treatment is frequently tear duct flushing. Eye drops will be used to give the antibiotic. A tiny catheter, also known as a cannula, is placed into the tear duct entrance after the eyelid is pushed out of the way. With a syringe and very little pressure, sterile fluid is softly inserted into the tear duct. In order to avoid contaminating the eye area, material and mucous are typically washed out this way and removed or cleaned. If the duct is not fully cleaned with the first surgery, which is not unusual, the procedure might need to be repeated in a few weeks. While sedation and anesthetic wear off, your dog is placed in recovery and is being watched.

  • tear duct exploration (a thin metal instrument called a probe is used to unclog the tear duct)
  • dilation of the balloon catheter (a thin and flexible tube called a catheter that expands like a balloon is used to remove the blockage)
