Eye Illnesses Though Many, Are Mostly Uncommon
Most eye illnesses are not terribly common, a fortunate situation as there are quite a number of illnesses that potentially could affect our vision. The most common of the eye illnesses is conjunctivitis, an inflammation of the eyelid or the whites of the eyes, of which there are several different types. Eye disorders, some of which may fall into the category of eye illnesses, also are related to aging, and we'll look into a few of these. Some eyelid illnesses are symptomatic of a systemic illness, such as diabetes. Some illnesses consist of skin disorders, which while often present in other places, sometimes are present near the eyes or in the eyelids.
Conjunctivitis - Conjunctivitis, though most often experienced by children, can occur at any age. A bacterial infection is one of the more common causes of this disease, though viral infections also may trigger the disorder. An allergic reaction is likely the most common trigger of conjunctivitis, quite often the result of the skin's sensitivity to cosmetics, or due to particles in the air. Often the things causing conjunctivitis are easily transmittable from one person to another, such as an infection or a virus. Although conjunctivitis in itself is usually not a serious illness, the symptoms may spread and eventually cause damage within the eye. Any onset of conjunctivitis should therefore never be allowed to go untreated, and if home remedies are not effective, a care provider or ophthalmologist should be contacted.
Other Problems - Conjunctivitis usually manifests itself as an itching and redness in the eyelashes or of the eye itself. Other symptoms of eye illnesses may include a feeling of actual pain, a partial loss of vision or a degradation in vision such as double vision or blurred vision, headaches, and uncontrolled movements in the muscles of the eyes and eyelashes. An illness affecting the muscles of the eyeball can affect the eyeball's movement upwards, downwards, to the left, or to the right, as different muscles control the different movements. Aging can cause the muscles controlling the eyelashes to atrophy, and the skin itself may become flabby and less elastic, potentially affecting vision. Blood vessels in the eyes at times become more rigid, either due to aging, a vascular problem, or disease of some kind. The result may be a lessening of the amount of light which reaches the retina, and a corresponding loss in the quality of one's vision.
Cataracts And Floaters - Cataracts are one of the more common eye illnesses, though cataracts mainly affect only older people and are treatable, usually by laser surgery. Another eye illness, though minor in nature, is the presence of floaters, those usually semitransparent bits and pieces we sometime observe, which may resemble microscopic cellular structures. Floaters are small bits of tissue which have broken away from the retina, and float about in the vitreous fluid in the eyeball. They are generally harmless.
Folliculitis - While folliculitis is normally defined and treated as a skin disorder, folliculitis in the eyelashes can create problems in the general vicinity of the eye. There are just under 50 follicles present in each pair of eyelashes, and if the follicles become plugged, there is always the possibility of an infection setting in. Any infection near the eyeball itself can in turn result in one of a number of eye illnesses, some of which can be difficult to treat.
It was mentioned earlier, that a systemic disease such as diabetes can cause an eye illness. Other systemic diseases which may impact the eyes are chickenpox, shingles, and the measles. Rheumatoid arthritis is also a direct cause of several eye problems. While eye illnesses due to a systemic disease may be difficult to prevent, most eye problems are preventable through sound hygienic practices, especially avoiding touching the area around the eyes with hands that are not clean.
