The word 'cataract' is used to describe any opacity or reduction in clarity of the lens of the eye. This can mean anything from mild cloudiness of the lens to complete opacification. Most people over the age of 50 have some haziness over the lens and the situation only becomes relevant if the lens opacity is interfering with vision. Cataract is the most common cause of blindness in the world today. It is, however, treatable with highly effective surgery and cataract removal is the most common operation carried out in the UK today. Cataract is the reduction in clarity of the lens of the eye (A).

Home Medical Reference Patient Education CAN CATARACTS BE PREVENTED? Although cataracts are not completely preventable, their occurrence can be delayed. Quitting smoking, avoiding overexposure to sunlight, drinking alcohol in moderation, and eating plenty of fresh fruits and vegetables can retard the formation of cataracts. No evidence exists that using eye drops or ointments or performing eye exercises will stem the onset of cataracts. Avoiding Ultraviolet Radiation The simplest and most effective way to protect against ultraviolet (UV) radiation is to stay out of the sun. A hat and cover-up should be worn outside, particularly when the sun is most intense (10 AM to 3 PM). A wide-brimmed hat can reduce eye exposure to UVB radiation by 30% to 50%. Because the sun's rays are highly reflective, sitting in the shade or under an umbrella by itself does not guarantee protection. Note: Avoidance of the sun should not be taken to extremes. Some sunshine is desirable. Moderate sun exposure provides an important source of vitamin D, which is essential for healthy bones. There is a link between lack of sun exposure and depression (known seasonal affective disorder, or SAD). Sunglasses.

For persons with an advanced cataract that covers a large portion of the eye lens, vision can be described as trying to see through a waterfall. What is a cataract? A cataract is a clouding or opaque area over the lens of the eye an area that is normally transparent. As this thickening occurs, it prevents light rays from passing through the lens and focusing on the retina the light sensitive tissue lining located in the back of the eye. This clouding is caused when some of the protein which makes up the lens begins to clump together and interferes with vision. In its early stages, a cataract may not cause a problem. The cloudiness may affect only a small part of the lens; however, the cataract may grow larger over time and affect more of the lens, making it harder to see. As less light reaches the retina, it becomes increasingly harder to see and vision may become dull and blurry. While cataracts cannot spread from one eye to another, many people develop cataracts in both eyes. What causes cataracts?

128. Cataracts and is responsible for the cloudyeyed appearance of older dogs but these lensesare still clear and the dog can still see through them; these are not cataracts http://www.marvistavet.com/html/body_cataracts.html

WHAT IS A CATARACT? The normal lens of the eye is a focussing device. It is completely clear and is suspended in position by special tissue fibers (called “zonules”) just inside the pupil. The lens focusses an image on the retina in the back of the eye in a process called “accommodation.” The focussing power of the dog’s lens is at least three times weaker than that of a human and a cat’s lens is at best half the focussing power as a human’s. (It is helpful to remember that dogs and cats have a sense of smell at least 1000 times more accurate than ours and this is their primary means of perceiving the world.) Despite its clarity, the lens is in fact made of tissue fibers. As the animal ages, the lens cannot change it’s size and grow larger; instead, it becomes more compact with fibers. This condition is called “nuclear sclerosis” and is responsible for the cloudy-eyed appearance of older dogs but these lenses are still clear and the dog can still see through them; these are not cataracts. The lens is enclosed in a capsule which, if disrupted, allows the immune system to see the lens proteins for the first time, recognize them as “foreign,” and attack. The resulting inflammation is painful and can be damaging to the eye. A cataract is an opacity in the lens.

KidsHealth Kids Health Problems of Grown-Ups Jake likes to visit his Grandma Fran on his way home from school. She always has special treats for him like his favorite homemade chocolate chip cookies, and she takes time to help him with his homework Lately, though, Jake's noticed that Grandma Fran has trouble reading some of his assignments. When Jake asked her if anything was wrong, Grandma Fran explained that she has cataracts - her glasses used to help, but now she needs to have an operation that will help her eyes see better again. An operation sounds scary, right? But actually many older people like Jake's grandma develop cataracts as they age. Cataract surgery is common and is almost always successful. To learn more about this common eye condition that most often affects older adults, read on. What Are Cataracts? A cataract say: cat -ah-rackt) is a clouding of the eye's lens that causes a loss of vision. A person's lens is normally made mostly of water and protein that is easy to look through, like a clear, clean window. As people get older, sometimes proteins in the lens stick together and form what is called a cataract. Looking out through these clumpy proteins in the lens is like trying to see through a piece of cloudy glass - things are difficult to see and may look blurry (out of focus).

Ask the Doctor Q: Cataracts My mother is suffering from cataracts and she loses her sight sometimes overnight, then it will clear up over time. But now she has lost her sight almost completely, except for her peripheral vision. Could this be due to a sudden growth of her cataracts? This is a worry to us both as she has already lost the sight of one eye after an operation to fix this problem. Also, is it possible for the blood clot to spread to her brain causing a stroke? Jon Dr Trisha Macnair responds Your description of your mother's changing eye problem does not sound like cataracts , which are an opacification or loss of transparency of the crystalline lens in the eye where light normally passes in. The changes that occur in the proteins in the lens to cause cataracts can be compared to the changes in the white of an egg when it is boiled. It has nothing to do with blood clots forming. The visual loss with cataracts is usually slowly progressive, and only rarely are there any improvements, which are limited to a sudden and temporary improvement in close-up vision. Neither do they usually cause just a central loss of vision.

MAIN SEARCH INDEX Cataracts Definition Description Causes and symptoms Diagnosis ... Resources Definition A cataract is a cloudiness or opacity in the normally transparent crystalline lens of the eye. This cloudiness can cause a decrease in vision and may lead to eventual blindness. Description presbyopia . It is a normal condition of aging , generally resulting in the need for reading glasses. The lens is made up of approximately 35% protein and 65% water. As people age, degenerative changes in the lens' proteins occur. Changes in the proteins, water content, enzymes, and other chemicals are some of the reasons for the formation of a cataract. The major areas of the lens are the nucleus, the cortex, and the capsule. The nucleus is in the center of the lens, the cortex surrounds the nucleus, and the capsule is the outer layer. Opacities can occur in any area of the lens. Cataracts, then, can be classified according to location (nuclear, cortical, or posterior subcapular cataracts). The density and location of the cataract determines the amount of vision affected. If the cataract forms in the area of the lens directly behind the pupil, vision may be significantly impaired. A cataract that occurs on the outer edges or side of the lens will create less of a visual problem. Cataracts in the elderly are so common that they are thought to be a normal part of the aging process. Between the ages of 52 and 64, there is a 50% chance of having a cataract, while at least 70% of those 70 and older are affected. Cataracts associated with aging (senile or age-related cataracts) most often occur in both eyes, with each cataract progressing at a different rate. Initially, cataracts may not affect vision. If the cataract remains small or at the periphery of the lens, the visual changes may be minor.

Glasses focus light, they do not improve transmission of light. If a window has dirt on it, even with binoculars we cannot see clearly through it. A cataract is a clouding of the human lens, impairing the clarity (not focus) of light entering the eye, but glasses can be changed, right? If your glasses are not providing perfect focus, then they can be changed to correct that element of your vision problem. Also the reading portion of the glasses can be strengthened to magnify print to overcome your blurring somewhat. What is a cataract? The human lens is like a bag of protein shaped like a lentil bean. The protein is surrounded by a clear capsule. A cataract is a clouding of all or a portion of the protein inside the bag. When should I have the cataract removed?

Cataracts Over half of those over 65 have some cataract development and most cases can be treated successfully with surgery. A cataract is not a skin that grows over the eye. A cataract is a clouding of part of the eye called the lens. Vision becomes blurred or dim because light cannot pass through the clouded lens to the back of the eye. What causes a cataract? Cataracts can form at any age, but most often develop as people get older. In younger people they can result from an injury, certain drugs, long-standing inflammation or illnesses such as diabetes. Some symptoms "I'm not seeing as well as I used to" People may notice that some things seem blurred round the edges, or that your glasses seem dirty or scratched. Seeing double The cloudiness in the lens may occur in more than one place, so that the light rays which reach the retina are split, causing a double image. Poor vision in bright light Bright light or very sunny days may make it more difficult to see. Change of colour vision As the cataract develops, its centre becomes more and more yellow, giving everything you see a yellowish tinge.

Home Up Contributors Submission Information ... Site Map Progressive opacity of the normally clear crystalline lens can lead to formation of a cataract(#22005). These changes may involve both the nucleus and the cortex of the lens (#22006, #22008). Nuclear changes are characterized by progressive crosslinking and insolubilty of crystalline proteins. This leads to a progressive hardening of the nucleus and discoloration which is initially yellow and can eventually become a dark brown or brunescent color(#22009, #22262). Cortical changes may begin as small peripheral water clefts with globular degenerative changes of the cortex. This may eventually coalesce into dense bands of opaque cortical material. In addition, lens epithelial cells may migrate posteriorly and form swollen bladder cells(#22011, #22188). Also, anterior lens epithelial cells may undergo a fibrous metaplasia leading to a thick fibrous plaque between the anterior lens capsule and the anterior epithelial cells (#22012). (#22197) is another slide of a cataract.

Cataracts and Dry Eye What is a Cataract Signs Treatment ... Take our survey What is a Cataract? The lens of the eye is transparent, allowing light to pass through it and be focused on the retina. A cataract is an opaqueness or cloudiness in the lens that prevents light from reaching the retina. A cataract usually starts out as very small opaque areas, then becomes larger. How rapidly the cataract becomes larger varies greatly depending on many factors including the location of the cataract within the lens, the age of the animal, and the cause of the cataract. The size of the cataract will effect how much vision your pet has. A very serious side effect of uncontrolled or poorly controlled diabetes is cataract formation. Diabetes-induced cataract formation is much more common in dogs than in cats. Not all diabetic dogs develop cataracts, but most do. Some dogs form cataracts so quickly that their vision is impaired and that's why the owner takes them to the vet, and then the diabetes is diagnosed. For other dogs, cataracts may form within weeks of diagnosis, or it may take months, or even years for cataracts to develop. If your vet tells you that your pet is developing a cataract, or has cataracts, it is very important that you get a referral to a certified veterinary ophthalmologist and have the specialist examine your pet's eyes. The ophthalmologist has special education, training, and equipment that will allow him or her to give your pet's eyes a full examination. The lens is not the only structure involved - the health of the entire eye should be evaluated.
