Extractions: Subscribe now >> More than two-thirds of people over the age of 60 will have a vision problem due to cataracts, so we usually think of the disease as one related to aging. However, cataracts the clouding of the lens inside the eye can strike at any age. The clouding of the lens scatters the light rays and prevents a clear image from being formed. The exact mechanism that causes cataracts is not well known. It is thought that the composition of the lens changes with time and contributes to the development of cataracts. Non-age-related cataracts might be caused by trauma to the eye, use of certain medications such as corticosteroids, exposure to radiation or ultraviolet light, or metabolic disturbances, such as diabetes. In addition, some people are born with cataracts. Chronic use of steroids for such conditions as asthma, rheumatoid arthritis or following organ transplantation can cause cataracts. Prolonged use of topical steroid creams on the eyelids may lead to cataract formation. Both the strength and duration of the steroid medication influence the formation of the cataract. Individuals who receive radiation therapy for cancer treatment or have excessive exposure to ultraviolet light from the sun are also at risk. In addition, diabetics account for a large portion of patients with non-age-related cataracts. The cause of diabetic cataracts is thought to be due to metabolic changes in the lens which occur secondary to hyperglycemia.

Extractions: Subscribe now >> Cataracts are the number one cause of poor vision among older adults. Over two-thirds of people over age 60 will have a vision problem due to cataracts. A cataract is a clouding of the eye's natural lens. Located behind the iris and the pupil of the eye, the lens focuses light on the retina in the back of the eye, which in turn allows you to see. The lens of the eye is similar to the lens of a camera. When the camera lens is not working properly you get a blurry photograph. When the lens of the eye becomes cloudy your vision decreases and things appear blurry. It is thought that most cataracts occur due to the natural aging of the body. However, other factors can be involved. Some diseases, such as diabetes or glaucoma, or the use of certain medications, such as steroids, are thought to increase the chance of a cataract occurring. Physical and chemical injury to the eye and exposure to intense heat or radiation are also associated with cataract development. Who can have a cataract?

Extractions: Recovery from Surgery What is a Cataract? A cataract is a clouding of the normally clear lens of the eye. When the amount of light that passes through the lens is reduced and scattered by the cataract, images are not correctly focused on the retina at the back of the eye. The result is that vision becomes poor - it can be compared to looking through a frosted or steamed window. There are many misconceptions about cataract. It is: Cataract formation affects only the lens of the eye and not any of the other important structures, such as the cornea, iris, retina or optic nerve. (See illustration below) Image courtesy of the American Academy of Ophthalmology A cataract will often worsen to a point where surgery is needed to remove the cloudy lens and replace it with a permanent artificial lens. top Causes and Cataract Development Cataracts develop as a normal part of the aging process. By the age of 60 about half of all people will have some cataract formation although it may be minor and not noticeable. By 70 years of age almost everyone will have some degree of cataract formation. Other causes of cataract may include family history, medical conditions such as diabetes, injury to the eye, medications such as steroids, various chronic eye diseases, and long-term, unprotected exposure to sunlight.

Extractions: To Find a Specialist Cataracts ataracts are lesions or spots in the interior of the lens of the eye. Dogs of any age can be affected (cats rarely get cataracts), and the disease is often inherited. In the early stages, cataracts cause blurring and distortion of vision, but are invisible to the naked eye. In later stages, they cause blindness and make the normally black pupil appear gray or white. People commonly mistake nuclear or lenticular sclerosis, which is an eye condition of old dogs, for cataracts. Lenticular sclerosis causes the pupil to appear a soft gray color. Unlike cataracts, it only causes a slight blurring of the vision and poor depth perception, but almost never causes blindness. Many advances in cataract surgery for dogs (cats rarely get cataracts) have been made in the last decade. Cataract surgery is now performed through a tiny incision. High frequency ultrasound is used to liquefy the lens, which is then removed by a needle. In most animals, an artificial lens is implanted in the sac that used to hold the damaged one. Success rates for cataract surgery are as high as 95% in dogs in which the eye is otherwise healthy, but early treatment gets the best results. If you suspect that your pet has cataracts, have him or her examined by a specialist in ophthalmology as soon as possible.

Since the eye works much like a camera, a cataract, much like a clouded lens, causes blurring or dimming of vision. Many cataract patients complain of poor distance vision, especially while driving. Glare can be especially troublesome while driving at night. Cataracts can also be responsible for double vision or altered color vision. Cataracts do not cause pain, tearing, redness or floaters.

Cataracts cataracts. WHAT ARE cataracts? A cataract is an opacity, or clouding, of the lensof the eye. The prevalence of cataracts increases dramatically with age. http://www.ucdmc.ucdavis.edu/ucdhs/health/a-z/26Cataracts/doc26.html
Extractions: A cataract is an opacity, or clouding, of the lens of the eye. The prevalence of cataracts increases dramatically with age. It occurs in the following way: The lens is an elliptical structure that sits behind the pupil and is normally transparent. The function of the lens is to focus light rays into images on the retina (the photosensitive tissue at the back of the eye). As people reach their mid-forties, biochemical changes occur in the proteins within the lens, causing them to harden and lose elasticity. This causes a number of vision problems. For example, loss of elasticity causes presbyopia , or far-sightedness, and the need for reading glasses in almost everyone as they age.

Extractions: Wilton Manors, Florida A nutritional cataract is caused by either a deficiency or excess of a nutrient resulting in a loss of transparency of the lens. Nutritional cataracts have been identified in various species, including rats, pigs, wolves, fish and guinea pigs as well as dogs and cats. In dogs and cats the most common cause of nutritional cataracts is being hand raised on milk replacer. It is usually possible to differentiate nutritional cataracts from inherited cataracts. The location of the cataract within the lens is fairly unique compared to other cataracts. The cataract is present within a few weeks of starting milk replacer. When combined with a history of being hand raised, the diagnosis is usually straight-forward. Also, inherited cataracts rarely occur at such early ages (with a few exceptions). Nutritional cataracts usually do not progress to interefere significantly with vision. Some will improve with age, as the young lens has some ability to repair itself. The younger the pup is when switched from bitch to hand raising, the more likely it is to develop nutritional cataracts. Also, the sooner it is started on solid food, the sooner the lens can stabilize and improve.

Extractions: Cataracts in Children What is a cataract? A cataract is a cloudy or opaque area that appears on the lens located directly behind the iris inside the eye. Normally, the lens is clear and allows light entering the eye to clearly focus an image on the retina. When cataracts develop, the light rays become scattered as they pass through the cloudy lens and the retinal image appears blurred and distorted. What causes cataracts in children? Cataracts can be present at birth (congenital) or can develop later in life. It has been estimated that one in every 250 children will develop a cataract. While the exact cause of cataracts found in both eyes (bilateral cataracts) is unknown, some are hereditary. Bilateral cataracts have also been associated with Down syndrome or other genetic disorders. Cataracts found in only one eye (unilateral cataract) are usually not associated with a particular disease. How will cataracts affect my child's vision? Many of the cataracts that are discovered in newborns are small and allow for excellent development of vision. Others can lead to blindness if not treated early.
