Here’s Looking At You: Eyes Part One

Apr 21, 2014 by     No Comments    Posted under: Tips & Advice

Last week Oreo’s owner called up confused. She explained that Oreo, her sweet little black and white tuxedo was absolutely fine, but she had started winking at her the day before. Oreo was eating and drinking and running around like her crazy self, so she couldn’t be in pain, but still, there was that wink. Our staff scheduled a visit for Oreo and I saw her that day. Indeed Oreo was perfectly healthy except that she had scratched the surface of her eye- the cornea. We started her on medication right away, including pain medication. The wink disappeared and her eye healed within a few days.

Cats are much more stoic than we are. Most of the time, they show very few outward signs of pain, so as pet owners we need to be detectives. If you have ever had an eye injury or infection, you know how painful that is. Cats feel the same pain as we do, they just don’t show it.

Eye injuries require prompt veterinary evaluation and treatment. Treatment with the wrong medication can prolong disease and in some cases, make things worse, so you will want your cat examined by your veterinarian in person, not over the phone.

Here are some things to look for, starting with the basics. Each of these signs warrants evaluation by your veterinarian.

  1. Redness: if one eye, or part of the eye is red, that means inflammation. This is most commonly caused by trauma or infection and often comes with pain.
  2. Is one eye closed? This means pain, even if everything else seems fine.
  3. Is there swelling around one or both eyes? Swelling is due to trauma, infection or inflammation.
  4. Is your cat rubbing at one eye? That’s her way of saying “This eye is hurt. Please make it better before I make it worse.”
  5. Is the third eyelid showing? This can indicate infection, inflammation, trauma or other diseases. Please see my previous blog about third eyelids.
  6. Discharge. The eyes are constantly producing some watery and some mucousy material to coat and protect the eye. Excess of either signals underlying disease. Colored (green or brown) mucous discharge is usually caused by infection.
  7. Excess tearing is often caused by irritation. Irritation = pain.
  8. What about the eyelids? Some cats’ eyelids don’t sit flat on the eye and can roll in, causing the eyelashes to rub on the eye. This causes painful trauma to the eye surface (cornea). Ever get a grain of sand in your eye? Now think 30 grains of sand. You get the picture.
  9. Is there a growth or bump on the eyelid? If so, this is best addressed early. If surgery is needed, it is always best to do before a growth gets too large, especially in this delicate area. Many (but not all) eyelid growths are benign.

In most cases, your family veterinarian can evaluate and treat your cat. Sometimes evaluation and treatment by a board-certified veterinary ophthalmologist is necessary. See http://www.acvo.org/ for more information.

That Mysterious Third Eyelid

Jun 5, 2011 by     22 Comments    Posted under: Tips & Advice

For many owners, the appearance of their cat’s third eyelid is cause for great concern and confusion.  Never fear- it can often indicate a problem, but with a little information, you can better determine why this might be happening and how quickly your cat needs professional medical attention.

First, a bit of background:  The third eyelid provides an extra layer of eye protection for cats and many other animals.  Other names for the third eyelid include the nictitating membrane, nictitans and haw.  Arising from the corner of the eye nearest the nose, the retractable third eyelid can be hidden from view or can extend across the surface of the eye.  It is white to light pink in color and lies on top of the eye, but underneath the eyelids.  It contains cartilage and a tear-producing gland at its base.  When irritated, it can appear reddened.

While birds and reptiles can actively move this protective eyelid into position, in cats the movement is passive. It is kept hidden by forward pressure of the eyeball in the socket. When danger to the eye is anticipated ( such as in a cat fight), cats use a special muscle behind the eye to pull it back into the socket slightly, allowing the third eyelid to quickly move up and across the surface of the eye. If the eye does become injured and painful, cats will use this special muscle to pull back the eye slightly and allow the third eyelid to cover the eye as protection.

Damage to the nerve control of the third eyelid will also result in a prominent (or more visible) third eyelid.  Damage affecting one eye can occur due to an injury or inflammation after surgery (especially ear or dental surgery).

If you notice that one of your cat’s third eyelids is covering one eye more than the other, it is likely that your cat has injured that eye.  Eye injuries are painful and can become serious quickly, so you should seek veterinary care right away.

What does it mean if both third eyelids are visible?  There are a variety of reasons for this to occur.  First of all, when cats are in a deep sleep or have been given a sedative, the third eyelids can become prominent.  If your cat has lost a lot of weight, the fat pad behind the eyes may also have decreased in size, changing the position of the eye in the socket and allowing the third eyelid to become visible.  Rarely, inflammation due to a neurologic, respiratory or intestinal infection can affect the nerve control of the third eyelid.   Your cat should be examined by a veterinarian in order to determine a likely cause and how best to treat the condition.

If you have never seen your cat’s third eyelid, and want to know what to look for, ask your veterinary at your cat’s next check-up.
