Your Dogs Eyes The Most Important Yet Overlooked Part Of Your Dogs Body

No other organ in your dogs body contains such an intricate and complex mechanism in such a small structure as the eyes. A thorough examination of the eye can only be made by your veterinarian, but hopefully through our brief description given here, you will as at least know enough to spot a problem when it arises.

The first seen when examining your pets eyes are the upper and lower eyelids specialized curtains to protect the eyes. Eyelids should be smooth and sharp. The eye margin or center of the lower lid should not turn in or turn out. Be sure the eyelids and hairs on the nose do not rub the eyeball. Sometimes these hairs can be distorted and misdirected and can irritate the eye. A smooth, pink tissue, called the conjunctiva, can be seen covering the inner surface of the lids.

The conjunction helps lubricate the eyeball and protect it from infection. The space between the eyelid conjunction and the eyeball conjunctiva is the conjunctiva sac. If the conjunctiva is red or swollen, or if there is a green or yellowish discharge, an inflammation of the tissue is present.

The cornea is the clear front window of the eye that bends the incoming light rays. The cornea can lose its clarity if it becomes inflamed or injured. Hairs and twigs can injure the cornea, especially in pop-eyed dogs. The sclera is the fibrous coat the gives the eyeball its ping-pong ball shape and dull white color. The sclera frequently takes on a yellow color, (jaundice) in dogs experiencing liver problems.

The iris controls the amount of light entering the back of the eye and gives your dogs eye its color. The black hole in the center of the iris is the pupil. It dilates (gets larger), to let more light enter in dim light, and constricts (gets smaller) in bright light. Cataracts are white opacities that block the lights passage through the eye, and can be seen by shining a bright light into the pupil of the eye. A normal aging process called senile cataracts, or nuclear sclerosis, is caused by a rearrangement of the fibers and a loss of water in the older lens.
