Symptoms of feline pet nasolacrimal duct obstruction.

Understanding Feline Nasolacrimal Duct Obstruction: Symptoms and What to Look For

Cats, with their enchanting eyes and playful antics, have a special way of winning our hearts. However, like any pet, they can experience health issues that require our attention. One such condition is nasolacrimal duct obstruction, a common problem that can affect our feline friends. In this article, we will delve into the symptoms of nasolacrimal duct obstruction in cats, helping you recognize the signs and take appropriate action.

What is Nasolacrimal Duct Obstruction?

The nasolacrimal duct is a small channel that connects the tear ducts in a cat's eyes to the nasal cavity. Its primary function is to drain tears from the eyes. When this duct becomes blocked or obstructed, it can lead to a range of uncomfortable symptoms for your furry companion.

Symptom 1: Excessive tearing (Epiphora)

One of the most noticeable symptoms of nasolacrimal duct obstruction is excessive tearing, also known as epiphora. If you notice that your cat's eyes are constantly watery or if there is a persistent tear stain beneath their eyes, it could be a sign of a blocked tear duct. This symptom occurs because the tears cannot properly drain through the obstructed duct, leading to overflow.

Symptom 2: Discharge from the eyes

In addition to excessive tearing, cats with nasolacrimal duct obstruction may exhibit discharge from their eyes. This discharge can vary in consistency, ranging from watery to thick and mucoid. It may also be accompanied by a foul odor, indicating an infection or inflammation.

Symptom 3: Squinting or blinking

Cats with blocked tear ducts may experience discomfort or pain in their eyes, leading to squinting or excessive blinking. If your cat seems to be having difficulty keeping their eyes open or if they are blinking more frequently than usual, it could be a sign of nasolacrimal duct obstruction.

Symptom 4: Redness or swelling around the eyes

Redness or swelling around the eyes is another common symptom of nasolacrimal duct obstruction. The blockage can cause irritation and inflammation, resulting in visible redness and swelling. In some cases, the conjunctiva (the mucous membrane that lines the inner surface of the eyelids) may also become inflamed.

Symptom 5: Nasal discharge

Since the nasolacrimal duct connects the eyes to the nasal cavity, a blockage can also lead to nasal discharge. If your cat has a runny nose along with the other symptoms mentioned, it could indicate a blocked tear duct.

Symptom 6: Pawing at the eyes

Cats with nasolacrimal duct obstruction may paw at their eyes in an attempt to alleviate discomfort. If you notice your cat excessively pawing at their eyes or rubbing their face, it could be a sign of a blocked tear duct.

What to Do if You Suspect Nasolacrimal Duct Obstruction

If you suspect that your cat may be suffering from nasolacrimal duct obstruction, it is essential to consult with your veterinarian. They will perform a thorough examination and may recommend diagnostic tests, such as a fluorescein dye test, to confirm the diagnosis. Treatment options may include medication, surgery, or other interventions, depending on the severity and underlying cause of the obstruction.

In conclusion, nasolacrimal duct obstruction can cause various uncomfortable symptoms for cats. By being aware of these symptoms and seeking prompt veterinary care, you can help ensure your feline companion receives the necessary treatment to alleviate their discomfort and maintain their overall health and well-being.
