Here are some signs and symptoms to look out for if your cat is experiencing an eye infection and what you can do about it.

Cat Eye Problems

Cat owners should always be on the lookout for eye problems. Unlike dogs, who use a combination of sight, hearing, and smell to become familiar with their surroundings, cats depend mostly on their eyesight for hunting and stalking their prey.

Watery eyes, frequent blinking, squinting, and pawing at their eyes, may all be signs that their eye is painful. Cats also have an extra eyelid, which is called the nictitating membrane. If this extra eyelid is visible, then something is most likely wrong. You should then:

  1. Examine the eye to see if you can recognize the cause. The best way to examine the eye is by using a single light source, such as a flashlight, preferably in a dark room. You can prevent the cat from panicking by using a pillowcase that is pinned around his neck in order to restrain him. Remember, If your pet is frightened, his eyes will dilate, preventing you from making an accurate observation.
  2. Try comparing one eye to the other. Look to see if they are of the same shape, color, and size. See if they bulge forward or are recessed backward. A discharge might be present, or the eye may be cloudy, hazy, or smoky. To test for vision, cover one eye and touch the other several times with your finger. If the cat has vision, he will blink when your finger approaches.

If your cat has a painful eye, you should seek immediate veterinary attention.

Signs and symptoms to look out for include:

  • Discharge: A clear discharge without redness and pain indicates a problem in the tear drainage system. Any discharge should alert you to the possibility of cornea or inner eye involvement. A thick, sticky mucus discharge, along with redness and inflammation, indicates pink eye or conjunctivitis.
  • Pain: Signs of pain include squinting, tearing, tenderness to touch, and avoidance of light. The nictitating membrane may protrude in response to pain. The common causes of painful eyes are injuries to the cornea and disorders affecting the inner eye.
  • Film Over the Eye: A whitish or opaque film that moves out over the surface of the eyeball is a protruded nictitating membrane.
  • Cloudiness: Loss of clarity or transparency in the eye indicates an inner eye disorder. Disorders that can cause a cloudy eye are keratitis, glaucoma, and cataracts.
  • Hard or soft eye: Changes in eye pressure are caused by disorders of the inner eye. The pupil might become fixed and fail to respond to light. A hard eye with a dilated pupil indicates glaucoma. A soft eye with a small pupil indicates inflammation of the inner structure of the eye.
  • Lid Irritation: These are conditions that cause swelling, crusting, itching, or hair loss of the eyelids.
  • Bulging or Sunken Eye: These are abnormal contours and positions of the eye.
  • Abnormal Movements: These are eyes that focus in different directions or jerk back and forth.
  • Cross-Eyed Gaze: This is common among Siamese cats and is accepted as normal; however, other forms are caused by muscle paralysis.
If your cat has a painful eye, you should seek immediate veterinary attention.

Cat Third Eyelid Problems

Every cat owner has found the one issue which causes the most amount of stress and anxiety for their cat. Some kitties are born with special needs that are hard to fix, while others take extra work and often money to take care of.

My two-year-old male cat Alvin has a problem with his third eyelid. This eyelid which is called the nictitating membrane folds over sideways causing him to have a strange look on his face. You can imagine his problems with his vision and sleeping. He is a very skittish and nervous little guy, so it has been challenging to find a way to treat this ailment.

Alvin

Alvin

When a cat's nictitating membrane is visible over the corner of the eye it is usually said to be protruding. If one eye is involved the probable cause is a painful eye condition due to a corneal injury or a foreign body in the eye. If both eyes are involved the condition is most likely caused by a feline viral infection. Since Alvin had this condition from birth, I am assuming that he had an upper respiratory infection that affected his one eye. 1 or 2-day old kittens born outside usually develop some kind of upper respiratory condition, most of the time mild, however, Alvin might have had complications. This third eyelid problem doesn’t seem to affect his playfulness or eating habits. He is also a healthy little guy.

The cat's third eyelid that is obfuscated should cause the owner to be aware of any chronic illness or disease which causes your cat to lose weight or become dehydrated. In those instances, you should visit your veterinarian.

Applying Eye Medicine

Ointments

Steady your cat's head with one hand and draw down on the lower lid to expose the inner surface of the eyelid. Apply ointment to the inside of the lower lid. Application directed to the eyeball is irritating and may cause the cat to jerk his head, and eye injury can occur.

Eye Drops

Eye drops can be applied directly to the eyeball. Steady the heel of the hand in which you are holding the dropper against the side of your cat's head. Tilt the nose upward and drop the medicine into the inner corner of his eye. Rub the eyelids gently in order to disperse the medicine. Frequent application of eyedrops usually is necessary because they tend to wash out with tears.

Use only preparations that are specifically labeled for ophthalmic use.

The source and diagnosis of any eye problems can usually be determined by one of the above symptoms. Pay very close attention to your cat to see if he/she exhibits one of them, and see your vet if necessary.

Lanna, This is not a fake site, and I have mentioned before, in the comments that I am not a veterinarian. I have access to several good vets and have experience with having over 20 cats treated with different type of eye problems, so I try to give the best educated answer on the topic. If I can not answer the topic I will either suggest seeing a vet or not answer. I am sorry If I gave any other impression about my knowledge on this topic.

My cat's eye - in one day - got a whitish film covering it completely like he's blind. Vets are closed in my area and the emergency pet hospital prescribed an antibiotic, which hasn't helped. He is 12, but this doesn't seem like a slow degenerative process from age. He experienced the same condition a few months prior and it cleared on its own. This time it's remained. There is discharge and slight swelling but no injury, and the vet did a pressure test for glaucoma (negative) and noted there is still vision. What can I do/try to help?

Hi My cat went blind a couple months ago and his eyes turned blue. yesterday i noticed one eye turned brown. what is going on?

Wocky on September 14, 2017:

I have noticed my cat intermittently winking and rubbing one eye. It tends to occur for a few hours at a time, separated by a week or even months. If I inspect her eyes, everything seems normal: no discharge or watering, no swelling, redness, or cloudiness. Then it seems to go away, but it has happened a few times. She seems to have no problem with her vision, and her eating, drinking, and litter habits are normal. How concerned should I be?

Hi my cat has redness coming from corner of both eyes no discharge or weeping it's not bothering her but looks sore what could this be please can you help

Hayley on November 24, 2016:

Hi, my cat's name is Coco, and she's been keeping her eye closed for a couple of days. It's weeping clear discharge and when I try to look under her eyelids it's very dark and almost looks like theres no eye there (but there is). Have no idea what this could be? She sometimes opens it a little but only very very slightly. She's not acting any different apart from keeping her eyes closed. Do I need to visit the vet or should it clear up on it's own?

what type of food should be given to cats when they are facing eyelid infection?

Claudia on December 07, 2015:

Hello, my cat's name is Bastet, and it seems she's been having some eye irritation lately. It happened suddenly where she just started keeping on eye closed, and didn't open it much at all. After a few days I wiped the outside of the eye with a warm damp cloth and now she occasionally opens it just a little or sometimes almost fully, but mostly keeps it closed. I've looked closely at her irritated and good eye and they look the same except for maybe one blood vessel I noticed on the bad eye. I figured it was just a stubborn foreign object irritation but it's been more than a week now and she's started to not eat her dry food as much. She still eats it but is reluctant, and when I gave her wet food she ate it all up very quickly. This is the only behavior change I've noticed. Is it just a foreign object or could it be something more?
