Some eye diseases such as macular degeneration and cataracts are common in elderly people. Other eye diseases can be caused by infection or may have an autoimmune basis. See your physician for diagnosis and treatment. Eye diseases can be a sign that there is an imbalance in your system. When you have an imbalance, you are susceptible to various diseases which can settle in weak areas of your body. You can check to see if there is an imbalance in your system.

Avian pox is another common disease that affects a bird’s eyes. This disease causes warty lesions on the head, legs, and feet, but cannot always be easily distinguished from conjunctivitis. Avian pox is transmitted by biting insects, by direct contact with infected birds or contaminated surfaces (e.g. feeders), or by ingestion of contaminated food or water. Just as with conjunctivitis, the infected bird becomes vulnerable to predation, starvation, or exposure. MORE PHOTOS

Conjunctivitis, which can be due to viral or bacterial infection, can cause pain that feels like grit in the eye. Uveitis is characterized by dull, aching pain. It may be an autoimmune condition. Glaucoma causes the pressure of the fluid in the eye to rise and is characterized by severe pain and may cause nausea or vomiting. Corneal ulcer due to a foreign object in the eye can produce severe redness and pain.

There are many different causes of the conditions collectively referred to as dry eye syndrome, including:

Sometimes microrganisms that cause health effects can be found in drinking water. However, as drinking water is thoroughly disinfected today, disease caused by microrganisms is rarely caused by drinking water. People that swim in swimming pools will find that the water they swim in is disinfected with either chlorine, ozone, UV or chlorine dioxide. But there are people that swim outside in surface water every year.

No. Our study found underlying disease in a higher percentage of the abnormally short girls than boys, but our study was looking at children referred to a specialty clinic and not at the general population. Turner syndrome, a genetic condition that causes short stature, occurs only in girls. Turner syndrome cases were not enough to account for the difference found in our study. It is very reasonable to look at your child’s growth curve together with your pediatrician.

Yes! While there are hundreds of different species, there are two basic classifications: floodwater and permanent water mosquitoes. Both types can transmit West Nile virus and other diseases.

Increased pressure within the eye as a result of various possible defects in the normal drainage system can lead to the disease known as glaucoma or "tunnel vision." This condition may be described as "looking at the world through a straw." People with "tunnel vision" must turn the head from side to side to avoid bumping into things or to see food on the edges of the plate since such vision is confined to objects directly ahead.

Unlike other refractive errors (myopia, hyperopia, and astigmatism), presbyopia is caused by changes in the optical lens.

The most common diseases caused by marine toxins in United States in order of incidence are scombrotoxic fish poisoning, ciguatera poisoning, paralytic shellfish poisoning, neurotoxic shellfish poisoning and amnesic shellfish poisoning. Scombrotoxic fish poisoning also known as scombroid or histamine fish poisoning, is caused by bacterial spoilage of certain finfish such as tuna, mackerel, bonito, and, rarely, other fish.

Researchers have little information about pregnancy and IC / PBS but believe that the disorder does not affect fertility or the health of the fetus. Some women find that their IC / PBS goes into remission during pregnancy, while others experience a worsening of their symptoms. The emotional support of family, friends, and other people with IC / PBS is very important in helping patients cope.

The evidence available says no. See the following site as starting points, http://www.pbs.org/wgbh/pages/frontline/implants/cron.html http://www.asps.asn.au/siliconeimplants/

There are several uncommon conditions that give rise to over-production of bilirubin. The bilirubin in the blood in these conditions usually is only mildly elevated, and the resultant jaundice usually is mild and difficult to detect.

Yes, there is a group of symptoms referred to as Computer Vision Syndrome. This condition includes eye fatigue, blurred vision, increased effort while focusing, dry eyes, transient ghosting/doubling of images, light sensitivity, possible increase in nearsightedness, and even head, neck, and backaches. These symptoms occur largely because the eyes were not designed to stare at, and perform "visual acrobatics," with a computer monitor all day.

I live in Perth, WA and have recently (over the past 6 weeks) started using frontline plus on my 2 year old Siamese X. He had a mild flea problem (about 4 or 5) on his body, so I immediately used the frontline, a week later they were twice as bad. I waited another week before using another pipette of frontline.. because they are meant to work for a month. And since then have used the last one. That's a 3 pack in 6 weeks. and the problem is worse than ever.

Blepharitis can often cause Dry Eye symptoms due to inflammation of the eye lid margins, which is caused by a bacterial infection (Staphylococci). This condition can compromise the quality of the tear film causing tears to evaporate more quickly. The bacteria produce waste material that can cause a mild toxic reaction leading to chronic red, irritated eyes. Click Blepharitis for treatment. LASIK surgery temporarily disrupts the ocular surface/lacrimal gland unit.

I subscribe to a fish-health e-mail list and this topic was brought up the other day. If I pasted the entire "conversation" I would probably be banned from the board, so I'll try and give a little overview of the theories. Popeye (exopthalmia) can be environmental, but can also be a side-effect of systemic bacterial infections such as fish TB. It seems that bad environment (water quality) is the cause more often than not, and is easily recified with waterchanges.

Only with extremely reckless operation. Laser beams should never be directly shined into the eyes. Even if that were to happen, most of us would blink so quickly the beam could do no real damage. We've heard some reports of temporary flash blindness from Class IIIa lasers but only when the beam was directed into an eye and the eyelid held open. Of course, that counts as extremely reckless operation.

the Cogswell Resource Library, McGreal Sight Center, Concord. At this library there are books, brochures, audio and videotapes and reference materials helpful to persons who are blind and visually impaired, their families, teachers. Items may be taken on a loan basis, some you may keep. Legal blindness - is an arbitrary definition used to determine eligibility for government disability benefits. In the United States: the criteria for legal blindness are: 1).

Vaccines themselves do not cause autoimmune disease, but in genetically predisposed animals they may trigger autoimmune responses followed by disease - as can any infection, drug, or a variety of other factors. Yes - For example, Leptospira bacterins are often the diluent for the viral antigen combination. The "viral cake" may be resuspended in sterile water, and the Leptospira bacterin be given separately at another site or time, or discarded.

Yes. In addition to Legionnaires' disease, the same bacteria also can cause a flu-like disease called Pontiac fever.

Hard-bodied ticks are carriers of several diseases that affect man and domesticated animals, including Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis. These diseases can be treated with antibiotics if diagnosed early. Notify your physician if you develop flu-like symptoms two to 21 days after a tick bite. For more information on these and other diseases carried by ticks, please refer to the following link: CDC: Lyme Disease

In the past, polio was a leading neurological cause of scoliosis. Adults who grew up with polio when epidemics were common often develop scoliosis as a result of their prior condition.

This is a condition which produces an allergy to the spores of the aspergillus moulds. It is quite common in asthmatics; up to 20% of asthmatics might get this at some time during their lives. ABPA is also common in cystic fibrosis patients, as they reach adolescence and adulthood. The symptoms are similar to those of asthma: intermittent episodes of feeling unwell, coughing and wheezing. Some patients cough up brown-coloured plugs of mucus.

No, some nematodes in the soil are not plant-parasites. Some merely feed on fungi or bacteria, or on rotting dead plant tissue, so they act as recyclers. Some nematodes also are internal parasites of the soil-inhabiting juvenile stages of various insects, including some insects like cutworms or weevil larvae. So like most other creatures, there are desirable nematodes as well as undesirable. Some nematodes even prey on other nematodes, helping to keep the overall population in balance.

Outside of the very different realm of true invasive mould infection, moulds produce two broad categories of diseases: Allergies and Toxicoses. The allergies are simply those of the classic forms of hay fever, asthma, rhinitis, and so forth. The toxicoses are much different. There are many, many different highly potent toxins made by some fungi. Generally, these toxins produce disease after their ingestion. Thus, a good clue will be that of a history of ingestion of mould-contaminated foods.

FEVR is a variable disease which means it varies in intensity from person to person. Severe cases of FEVR can cause a number of eye problems such as Retinal Detachment - Why is a retinal tear considered a serious problem? When a tear in the retina occurs, the liquid in the vitreous cavity may pass through the tear and get under the retina. The liquid collects under the retina and lifts it up off the back wall of the eye.
