Feline Squinting, Tearing, and Corneal Pain

Cats are known for hiding signs of discomfort, which is why noticeable squinting or excessive tearing should never be ignored. If your cat is keeping one eye partially closed, producing excessive tears, or showing signs of eye irritation, they may be experiencing significant ocular pain. At Animal Eye Specialists in Plano, TX, our veterinary ophthalmologists diagnose and treat corneal ulcers, eyelid abnormalities, and other painful feline eye conditions using advanced diagnostic techniques and microsurgical procedures.

Why Is My Cat Squinting?

Squinting is often one of the earliest signs of eye pain in cats. Even minor injuries or irritation affecting the cornea can cause considerable discomfort.

Common causes of squinting and tearing in cats include:

• Corneal ulcers
• Corneal injuries
• Feline Herpesvirus (FHV-1)
• Entropion
• Foreign objects in the eye
• Conjunctivitis
• Uveitis
• Eye trauma
• Chronic corneal disease

Because many of these conditions require different treatments, a comprehensive ophthalmic examination is essential for an accurate diagnosis.

Corneal Ulcers in Cats

A corneal ulcer is a wound or defect affecting the surface of the cornea. These ulcers can develop from scratches, trauma, foreign material, infections, or viral flare-ups associated with Feline Herpesvirus.

Common signs of a corneal ulcer include:

• Squinting
• Excessive tearing
• Eye redness
• Eye discharge
• Sensitivity to light
• Frequent blinking
• Pawing at the face

Without prompt treatment, corneal ulcers can deepen and threaten both vision and the structural integrity of the eye.

Feline Herpesvirus and Corneal Disease

Feline Herpesvirus is one of the most common causes of chronic eye disease in cats. During flare-ups, the virus can trigger inflammation and corneal ulceration, leading to pain, tearing, and recurring eye problems.

Because herpes-related eye disease can become chronic, specialized treatment and ongoing monitoring are often necessary to minimize complications.

Entropion in Cats

Entropion occurs when the eyelid rolls inward, causing the eyelashes and surrounding hair to rub against the surface of the eye.

This constant friction can result in:

• Chronic tearing
• Squinting
• Corneal ulcers
• Eye irritation
• Inflammation
• Discomfort

Correcting the eyelid position is often necessary to prevent ongoing damage and provide lasting relief.

Advanced Diagnostic Testing

At Animal Eye Specialists, we use specialized ophthalmic equipment to determine the cause of your cat's pain and evaluate the overall health of the eye.

Corneal Evaluation

A detailed corneal examination allows us to identify ulcers, injuries, scarring, and other abnormalities affecting the surface of the eye.

Comprehensive Ophthalmic Examination

A complete eye examination helps evaluate the eyelids, cornea, tear production, and internal structures of the eye to ensure all contributing factors are identified and addressed.

Corneal Repair Procedures

Some corneal ulcers require more than medical treatment alone. Deep, non-healing, or complicated ulcers may benefit from advanced corneal repair procedures designed to stabilize the eye and promote healing.

Our ophthalmology team performs specialized corneal surgeries aimed at preserving vision, reducing pain, and protecting the long-term health of the eye.

Eyelid Reconstruction and Entropion Surgery

When structural eyelid abnormalities such as entropion are present, surgical correction may be recommended.

Using delicate microsurgical techniques, we carefully reposition the eyelid to eliminate irritation, restore normal function, and prevent further corneal damage. These procedures can significantly improve comfort and reduce the risk of recurring ulcers.

When Should You Schedule an Evaluation?

You should seek a specialist evaluation if your cat develops:

• Squinting in one or both eyes
• Excessive tearing
• Eye redness
• Eye discharge
• Frequent blinking
• Signs of eye pain
• Cloudiness of the eye
• Recurrent eye problems

Early diagnosis and treatment can help prevent complications and improve your cat's comfort.
