A List of Common Eye Conditions in Felines
Cats have very unique and beautiful eyes. They can detect much more light than we can, however, their colour vision is limited. Threats to healthy eyes include injuries, conditions and diseases.
The following are considered common eye conditions or problems in felines:
This is a tricky one since symptoms are very similar to other conditions and problems. So, if you notice redness or discharge (especially if it doesn’t go away or gets worse) visit a vet.
The eye lens is the typically transparent structure in the centre of the eye behind the pupil. Cataracts, that cause the lens to appear milky white or cloudy gray, can result in vision problems, including blindness.
- Corneal Ulcers
The eye’s clear surface tissue is called the cornea which admits light into the eye. Open sores in this area are called corneal ulcers. Causes include injury, infection, tear production issues or other abnormalities. Signs and symptoms include cloudy cornea, pain, squinting, redness and in some cases discharge.
- Discolouration of the Iris
Iris melanosis manifests as brown ‘freckles’ on the coloured rim of tissue around the pupil typically in cats around 7 years and older. When a dark pigment appears on the iris it can be a sign of iris melanoma (a type of cancer).
Glaucoma in cats is an emergency. When eye fluids are unable to drain, eye pressure increases. Affected cats are usually in pain and can lose their vision and even their eyes. There are many causes. Signs and symptoms include cloudy, red, weepy and sometimes enlarged eyes.
Causes: bacteria, fungi, parasites and viruses. Possible signs and symptoms: discharge, redness, swelling, rubbing, squinting, sneezing and nasal discharge.
Physical injury (a cut, puncture or scratch) can be caused by accidents, fights and materials getting stuck in the eye. Signs and symptoms: redness, swelling, pain, discharge and visible damage.
Other diseases include:
- Conjunctivitis (pink eye)
- Dendritic corneal ulcers
- Nasolacrimal duct obstruction (NLDO)
If you think your cat might have an eye condition or injury, visit a vet.
