- Cataracts Facts. 1  Cataracts are changes in clarity of the natural lens inside the eye that gradually degrade visual quality. The natural lens sits behind the colored part of the eye (iris) in the area of the pupil, and cannot be directly seen with the naked eye unless it becomes extremely cloudy.

Cataract Cataract. 1  Cataract is a normal age related condition that causes a gradual cloudy or misty change to the lens of the eye. The lens is a clear transparent structure located behind the iris and the pupil. 2  Cataract changes can occur in different areas of the lens giving rise to very different types of cataract.

Cataracts: 75% of Dogs Develop Blindness within 1 Year of This Diagnosis Both dogs and cats can get cataracts, but they are much more common in dogs. Feline Cataracts Cataracts are actually rare in cats, and are usually caused by an eye infection or injury to the eye. Uveitis is a common feline inflammatory eye condition that is often a suspected underlying cause of cataract formation.

Eyes and Chronic Kidney Disease Cataracts occur when the lens of your eye becomes cloudy. The lens of the eye is normally clear. Its purpose is to focus the light coming in from the pupil to the retina at the back of the eye. A cataract scatters the incoming light and can make everything look blurry.

Cataracts Cataract Causes. The lens is made mostly of water and protein. Specific proteins within the lens are responsible for maintaining its clarity. Over many years, the structures of these lens proteins are altered, ultimately leading to a gradual clouding of the lens.

Overview At first, the cloudiness in your vision caused by a cataract may affect only a small part of the eye's lens and you may be unaware of any vision loss. As the cataract grows larger, it clouds more of your lens and distorts the light passing through the lens. This may lead to more noticeable symptoms.

Cataract A cataract is a dense, cloudy area that forms in the lens of the eye. It develops slowly and eventually interferes with your vision. A cataract is a dense, cloudy area that forms in the lens of the eye. A cataract begins when proteins in the eye form clumps that prevent the lens from sending clear images to the retina. The retina works by converting the light that comes through the lens into signals.

Pediatric Cataract and Other Lens Abnormalities What causes cataracts? A child may be born with the disease (congenital), or it may develop later in life (acquired). Possible causes of cataracts include the following: Trauma; Diabetes; Poisoning; Steroid use; Other childhood diseases, such as rheumatoid arthritis; Complications from other eye diseases, such as glaucoma

- However, if the lens is clouded by a cataract, light is scattered so the lens can no longer focus it properly, causing vision problems. The lens is made of mostly proteins and water. Clouding of the lens occurs due to changes in the proteins and lens fibers.

Cataracts This is our understanding of the cause of an age-related cataract. Over time, the cataract may become denser or cloud more of the lens, making it more difficult to see through. A cataract is not a growth or tumor. There are many causes of non age-related cataracts or secondary cataracts.

What are the symptoms of cataracts? Cataract is a condition in which the lens of the eye becomes cloudy. Symptoms include blurred, cloudy, or double vision; sensitivity to light; and difficulty seeing at night. Without treatment, cataracts can cause blindness.

The Cost of Cataract Surgery Cataracts cause glare. Another way your cataract can be considered medically necessary is if you bothered by glare. Your eye doctor will do a test to measure the effect of glare on your vision. It is call a “BAT” test where a bright light is shined at your eyes while you try to read the eye chart.

Overview Cataracts generally develop in both eyes, but not evenly. The cataract in one eye may be more advanced than the other, causing a difference in vision between eyes. Types of cataracts. Cataract types include: Cataracts affecting the center of the lens (nuclear cataracts). A nuclear cataract may at first cause more nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and further clouds your vision. As the cataract slowly progresses, the lens may even turn brown.

Cataracts Inflammatory disease of the eye, such as iritis or uveitis, may cause or accelerate the development of cataract in the involved eye. There are many genetic illnesses that are associated with the development of secondary cataracts.

Cataracts Types of cataracts include: A subcapsular cataract occurs at the back of the lens. People with diabetes or those taking high doses of steroid medications have a greater risk of developing a subcapsular cataract. A nuclear cataract forms deep in the central zone (nucleus) of the lens. Nuclear cataracts usually are associated with aging.
