🐾 Vet’s Guide to Blepharitis in Cats: Causes, Symptoms & Treatment in 2025 🐾

By Dr Duncan Houston BVSc

Blepharitis, or inflammation of the eyelids, is a common condition in cats that can cause discomfort and lead to more serious eye issues if left untreated. Understanding the causes, recognizing the symptoms, and seeking prompt veterinary care are essential for maintaining your feline friend's ocular health. This guide provides comprehensive information on blepharitis in cats, tailored for Australian cat owners in 2025.

🔬 Understanding Blepharitis

Blepharitis refers to the inflammation of the eyelid margins, which can affect one or both eyes. It often occurs alongside conjunctivitis (inflammation of the conjunctiva) and can be acute or chronic, depending on the underlying cause. The condition may lead to redness, swelling, and discomfort, prompting cats to rub or scratch their eyes, potentially exacerbating the issue.

🦠 Causes of Blepharitis

Blepharitis in cats can result from various factors, including:

• 🐾 Infections: Bacterial (e.g., Staphylococcus), fungal (e.g., ringworm), or parasitic (e.g., Demodex mites) infections can lead to eyelid inflammation.
• 🐾 Allergies: Environmental allergens, food sensitivities, or reactions to medications may cause allergic blepharitis.
• 🐾 Autoimmune Disorders: Conditions like pemphigus or systemic lupus erythematosus can manifest with eyelid inflammation.
• 🐾 Congenital Abnormalities: Structural issues such as entropion (inward rolling of the eyelid) can irritate the eye and lead to inflammation.
• 🐾 Trauma: Injuries to the eye or surrounding area can result in blepharitis.
• 🐾 Neoplasia: Tumors affecting the eyelid may cause localized inflammation.

🐱 Recognizing Symptoms

Signs of blepharitis in cats include:

• 🐾 Swollen, red, or crusty eyelids
• 🐾 Discharge from the eyes, ranging from watery to thick and purulent
• 🐾 Excessive blinking or squinting
• 🐾 Pawing or rubbing at the eyes
• 🐾 Hair loss around the eyes
• 🐾 Sensitivity to light (photophobia)
• 🐾 Concurrent conjunctivitis

🧪 Diagnosis

Diagnosing blepharitis involves a thorough veterinary examination, which may include:

• 🐾 Physical Examination: Assessing the eyes and eyelids for signs of inflammation, discharge, or structural abnormalities.
• 🐾 Ophthalmic Tests: Utilizing tools like slit-lamp examination or fluorescein staining to evaluate the eye's surface and detect ulcers.
• 🐾 Laboratory Tests: Performing skin scrapings, cultures, or blood tests to identify infectious agents or underlying systemic conditions.
• 🐾 Imaging: In some cases, imaging studies may be necessary to assess deeper structures or rule out neoplasia.

💊 Treatment Options

Treatment strategies depend on the underlying cause of blepharitis:

• 🐾 Medications: Administering topical or systemic antibiotics, antifungals, or antiparasitic agents to address infections.
• 🐾 Anti-inflammatory Therapy: Using corticosteroids or immunosuppressive drugs to reduce inflammation, particularly in autoimmune cases.
• 🐾 Allergy Management: Implementing dietary changes, antihistamines, or immunotherapy to control allergic reactions.
• 🐾 Surgical Intervention: Correcting anatomical abnormalities like entropion through surgical procedures.
• 🐾 Supportive Care: Employing warm compresses, eyelid hygiene, and e-collars to prevent self-trauma and promote healing.

🛡️ Prevention Strategies

Preventing blepharitis involves proactive measures:

• 🐾 Maintaining regular veterinary check-ups to monitor eye health.
• 🐾 Keeping your cat's living environment clean and free from allergens.
• 🐾 Ensuring proper grooming, especially for breeds with facial folds.
• 🐾 Managing underlying health conditions effectively.
• 🐾 Promptly addressing any eye injuries or infections.

📍 Considerations for Australian Cat Owners

In Australia, certain factors may influence the prevalence and management of blepharitis:

• 🐾 Climate: Warm, humid conditions can promote the growth of fungi and parasites, increasing infection risks.
• 🐾 Wildlife and Insects: Exposure to various insects and wildlife may lead to bites or allergic reactions affecting the eyes.
• 🐾 Breed-Specific Risks: Brachycephalic breeds like Persians and Himalayans are more prone to eyelid issues due to their facial structure.
