Have you noticed your dog with red eyes? If you have, never take it for granted as this could be a sign of a very dangerous condition. While it may not all the time be a cause for alarm, most of the time it is, so it is best to have your dog checked by his vet.

Most of us probably relate conjunctivitis (pink eyes) to red eyes, but in truth, conjunctivitis is but one of the conditions for red eyes, and nothing more. Red eyes can be caused by something a lot more serious than conjunctivitis.

To get a better understanding, it is necessary for us to know the possible reasons for its occurrence. While you may think that eye irritation is brought about by external particles are the likely culprit, it is much more complicated than that. Four of the common factors that cause red eyes are:

Glaucoma

Superficial Keratitis

Anterior Uveitis

Conjunctivitis

Glaucoma

This condition is brought about by an increased pressure in the eyes which causes it to turn red. Glaucoma is a very serious condition that may cause damage to the eyes; internal structures will be displaced, in most cases, because of rupturing brought about by increased production of liquid. While liquid production is normal, the problem when a dog has glaucoma is that there is no way to drain the liquid which then results in a buildup, thus causing it to burst.

How do you treat Glaucoma? Usually, doctors prescribe antibiotics to rid of pressure and liquid in the eyes, as well as dilation of the pupils.

Superficial Keratitis

A condition that is shown by an inflammation of the cornea, Superficial Keratitis is caused by the following: bacteria, virus, allergic reactions, traumatic situations, or even constant irritation. An eye condition exclusive to dogs, it is actually very common for all breeds, and its chronic condition is referred to as Pannus.

It starts out as a grayish-pink line that develops in the eyes, which if left untreated, will cause blindness. You will notice that your dog’s cornea becomes opaque, and will be worsened if exposed to too much sun.

Treatment used is antibiotics. Proper hygiene is also important so that the condition will not get worse.

Anterior Uveitis

Brought about by virus, bacteria, or a traumatic experience, Anterior Uveitis can be diagnosed as an inflammation of the ciliary or the iris. Dogs with cancer will also most likely develop this condition. You will notice that your dog’s eyes are always formulating tears, and the iris will look swollen, with a cloudy cornea. It could also cause the pupils to contract because protein level goes up abnormally. If this condition is not treated immediately, this could lead to cataracts or glaucoma, and at times, secondary lens luxation, particularly for small breeds.

Treatment is through anti-inflammatory drugs to dilate the eyes and minimize the level of pain. If you think your dog has Anterior Uveitis, have him checked right away as it could signal the presence of cancer.

Conjunctivitis

Also coined as ‘pink eye,’ conjunctivitis can cause red eyes. This condition takes place because of allergic reactions, irritation, or infection. Conjunctivitis is not as serious a condition as the rest, but it can still bring about excessive discharge due to infection. Treatment can be in the form of antibiotics. Hygiene is also just as important to keep your dog’s eyes clean.
