Top 30 Doctor insights on: Prominent Cortical Sulci Sparing the nucleus: Cortical cataracts are in a layer of the lens outside of the nucleus which is the center of the lens. They are sometimes congenital. Depending upon the density they may disturb the vision but sometimes are thin enough not to be a problem.

Cataracts A cataract occurs when the normally clear lens in the eye becomes cloudy. Cataracts are the leading cause of correctable reduced vision worldwide. Most cataracts develop slowly with normal aging. However, cataracts also may be related to genetic diseases and medical conditions such as diabetes.

Cataract A cataract is a clouding of the normally clear, transparent lens of the eye. A cataract is not a tumor or growth of new tissue over or in the eye. Rather it is a fogging and loss of clarity of the lens itself. The lens is located in the eye just behind the iris and the pupil. Light entering the eye is focused by the lens onto the retina. When a cataract forms, the lens is no longer able to focus the light clearly. Therefore, your vision becomes cloudy. An early cataract may cause few problems with vision.

Cataracts A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over age 40 and is the principal cause of blindness in the world. In fact, there are more cases of cataracts worldwide than there are of glaucoma, macular degeneration and diabetic retinopathy combined, according to Prevent Blindness America (PBA). Today, cataracts affect more than 22 million Americans age 40 and older.

Cataracts A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are related to aging. Cataracts are very common in older people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery. A cataract can occur in either or both eyes. It cannot spread from one eye to the other. What is the lens? The lens is a clear part of the eye that helps to focus light, or an image, on the retina. The retina is the light-sensitive tissue at the back of the eye. In a normal eye, light passes through the transparent lens to the retina. Once it reaches the retina, light is changed into nerve signals that are sent to the brain.

Cortical visual impairment The term neurological visual impairment (NVI) covers both CVI and total cortical blindness. Delayed visual maturation, another form of NVI, is similar to CVI, except the child's visual difficulties resolve in a few months. Though the vision of a person with CVI may change, it rarely if ever becomes totally normal.

- A Cataract is a clouding of the normally transparent lens within your eye. The lens is located directly behind the pupil and normally assists in focusing light for clear vision. As the cataract worsens, it prevents light from coming through your pupil and focusing clearly on the retina.

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.

Cataracts Cataract Overview. 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.
