The Most Common Eye Problems in Cats Explained

Eye problems in cats can develop quickly, and the early signs are not always dramatic. Extra tearing, occasional squinting or slight cloudiness may be the first indication that something is uncomfortable. Because cats often conceal pain, a condition can be more advanced than their behaviour suggests.

Some feline eye problems are straightforward to manage, while others can threaten sight or reflect illness elsewhere in the body. Similar symptoms can also have very different causes, so photographs and home remedies are not enough to make a diagnosis. A veterinary eye examination is the safest way to identify the problem and begin appropriate care.

Signs of an Eye Problem in Your Cat

Healthy eyes look clear and comfortable, without persistent discharge or squinting. Contact your veterinary team if you notice:

• Redness, swelling or a prominent third eyelid
• Watery, mucus-like or coloured discharge
• Squinting, frequent blinking or keeping an eye closed
• Rubbing or pawing at the face
• Cloudiness, a colour change or visible injury
• Pupils that appear different sizes
• Difficulty navigating, jumping or finding familiar objects

These changes may affect one or both eyes. Subtle changes deserve attention, particularly if they appear suddenly or your cat seems uncomfortable.

Common Feline Eye Conditions

Conjunctivitis and corneal ulcers

Conjunctivitis is inflammation of the tissue around the eye, often causing redness, swelling and discharge. Possible causes include infection, irritation, trauma or another eye condition. Some cats may also sneeze or develop nasal discharge.

A corneal ulcer is damage to the clear surface of the eye. Scratches, foreign material, infection or eyelid abnormalities can contribute. Ulcers are painful and may cause marked squinting, tearing, rubbing or cloudiness, so prompt assessment is important.

Entropion and blocked tear ducts

Entropion occurs when the eyelid rolls inwards and fur rubs against the eye. This may cause watering, redness, squinting and corneal ulceration. Eyelid anatomy, inflammation, pain or scarring can contribute, and corrective surgery may be recommended in persistent cases.

Tears normally drain into the nose through the nasolacrimal ducts. If a duct becomes narrowed or blocked, tears may overflow onto the face, cause staining or contribute to recurring discharge. Inflammation, infection, foreign material or facial anatomy may be involved. Your vet may recommend tests or flushing to assess the drainage pathway.

Uveitis, glaucoma and changes in vision

Uveitis is inflammation inside the eye and may cause pain, cloudiness, redness or changes in pupil size. It can sometimes be linked to a wider health condition. Glaucoma involves increased pressure within the eye and can cause pain and permanent vision loss; possible signs include an enlarged or cloudy eye, a dilated pupil and squinting.

Cataracts cause clouding within the lens, while retinal disease, high blood pressure and other conditions may affect sight without obvious surface irritation. Cats may bump into objects, hesitate at steps or misjudge jumps. Sudden changes in vision require immediate veterinary attention.

How Cat Eye Problems Are Diagnosed

An examination allows the vet to assess the eyelids, tear drainage, cornea, pupils and structures inside the eye. Tests may include a special stain to reveal corneal damage, measurement of tear production or eye pressure, and examination of the retina. Samples, blood tests or imaging may be advised if infection, trauma or a wider health condition is suspected.

These checks matter because treatments are not interchangeable. Medication suitable for one condition may be ineffective or harmful for another. Never use leftover eye drops, human medication or another pet’s prescription unless your vet directs you to do so.

When Does a Cat Need Veterinary Attention?

Arrange an assessment promptly for persistent discharge, redness, swelling or watering. Seek urgent veterinary advice for an injury, sudden cloudiness, unequal pupils, marked squinting, a bulging eye or an abrupt change in vision.

Prevent your cat from rubbing the eye if you can do so safely, but do not try to open a painful eye or remove an object yourself. Early diagnosis gives the best opportunity to protect comfort and sight.

Calm, Cat Friendly Eye Care

Eye examinations and drops can feel intrusive when a cat is already sore. At our cat clinic in Abu Dhabi, gentle handling, quiet cat-specific spaces and time to acclimatise help reduce fear and support a more comfortable assessment.

If medication is prescribed, ask the team to demonstrate how to give it calmly and safely. Tell us if treatment becomes difficult so we can help you find a lower-stress approach without compromising care.

Conclusion

Common eye problems in cats can look remarkably similar, but their causes and treatments differ. Redness, discharge, squinting, cloudiness or changes in vision should never be diagnosed from appearance alone.

If you notice a change in your cat’s eyes, contact German Veterinary Clinic. Our team can examine them carefully, explain the findings and recommend the most appropriate next step.
