Blocked Tear Duct Cat

A blocked tear duct (epiphora) in occurs when tears cannot drain through the nasolacrimal duct into the nose, causing them to spill over onto the face. While often a cosmetic issue, chronic blockages can lead to skin infections and irritation from moisture. 🛠️ Common Causes

As any cat owner knows, our feline friends are prone to a variety of health issues, including eye problems. One common condition that affects cats is a blocked tear duct, also known as nasolacrimal duct obstruction. This condition occurs when the tear duct, which is responsible for draining tears from the eye into the nasal cavity, becomes blocked. In this essay, we will discuss the causes, symptoms, and treatment options for blocked tear ducts in cats. blocked tear duct cat

epiphora (excessive tearing). Vetlexicon +1 Watery Eyes: Constant wetness in the corners of the eyes or beneath them. Tear Staining: Reddish-brown or dark discoloration of the fur along the path of the tears. Skin Irritation: Chronic moisture can cause redness, itching, hair loss, and "facial dermatitis". Odor: Foul-smelling bacteria may grow in the damp fur. Discharge: Blockages caused by infection (dacryocystitis) may produce milky, yellow, or green mucus. VCA Animal Hospitals +6 2.

PubMed Central (PMC) (.gov) Show all Facial Anatomy: Common in brachycephalic (flat-faced) breeds like Persians and Himalayans due to the shape of their muzzle. Inflammation/Infection: Swelling from conjunctivitis or respiratory infections can pinch the duct shut. Physical Obstruction: Foreign material (e.g., grass seeds) or inflammatory debris can lodge in the duct. Hereditary Defects: Some cats are born without a "puncta" (the opening where the duct meets the eye). Dental Issues: Because the duct passes near tooth roots, abscesses or severe dental disease can compress it. Wiley Online Library +11 3. Diagnosis Veterinarians typically use the following methods to confirm a blockage: Fluorescein Dye Test: A yellow-green dye is placed in the eye. If the duct is clear, the dye should appear at the nose or mouth within 5–10 minutes. Duct Flushing: Under sedation, a veterinarian may insert a tiny tube (cannula) to flush saline through the duct to check for resistance. Imaging: X-rays with contrast dye (dacryocystorhinography), CT scans, or MRIs can identify tumors or structural abnormalities. VCA Animal Hospitals +3 4. Treatment Options Medical Management: If caused by inflammation, vets may prescribe antibiotic or anti-inflammatory eye drops. Manual Flushing: Sometimes the act of flushing with saline is enough to clear minor debris. Surgical Correction: Imperforate Puncta: Creating a surgical opening for the duct. Stenting: Placing a tiny tube to keep the duct open during healing. New Pathway: In severe cases, a new drainage route to the nose or mouth may be surgically created. MSD Veterinary Manual +7 5. Home Care & Prevention Daily Cleaning: Gently wipe the under-eye area with a warm, damp cloth to prevent tear staining and skin infections. Veterinary Monitoring: Seek a vet if discharge changes color, the eye appears painful (squinting), or the skin becomes raw.

Cats produce tears to lubricate and clean their eyes. Normally, these tears drain through tiny openings (puncta) in the inner corners of the eyes, traveling down the nasolacrimal duct into the nose and throat. When that duct gets blocked, tears spill over the eyelid and down the face—a condition called epiphora. One common condition that affects cats is a

The symptoms of a blocked tear duct in cats can vary depending on the severity of the condition. Common symptoms include:

First, never use human eye drops or try to flush the duct yourself. A vet will perform a simple fluorescein dye test—green dye dripped into the eye. If it doesn’t appear at the nose within a few minutes, the duct is likely blocked. They may also flush the duct with saline under sedation.

: Swelling from respiratory infections (like feline herpesvirus) can narrow or close the duct.
