- NCI2016_NICHD_1602D:Opacity of the crystalline lens.|NCI2016_NCI-GLOSS_1602D: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. There are many different types and causes of cataracts. They may occur in people of all ages, but are most common in the elderly.|NCI2016_CTCAE_1602D:A disorder characterized by partial or complete opacity of the crystalline lens of one or both eyes. This results in a decrease in visual acuity and eventual blindness if untreated.|NCI2016_CDISC_1602D:Opacity of the crystalline lens.

Some cataracts appear in infancy or in childhood, but most develop in older individuals. (Sternberg Diagnostic Surgical Pathology, 3rd ed.)|MSH2017_2016_08_12:Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)|MEDLINEPLUS_20151021:<p>A cataract is a clouding of the lens in your eye. It affects your vision. 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.</p> <p>A cataract can occur in either or both eyes. It cannot spread from one eye to the other. Common symptoms are</p> <ul> <li>Blurry vision</li> <li>Colors that seem faded</li> <li>Glare - headlights, lamps or sunlight may seem too bright. You may also see a halo around lights.</li> <li>Not being able to see well at night</li> <li>Double vision </li> <li>Frequent prescription changes in your eye wear </li> </ul> <p>Cataracts usually develop slowly. New glasses, brighter lighting, anti-glare sunglasses or magnifying lenses can help at first. Surgery is also an option. It involves removing the cloudy lens and replacing it with an artificial lens. Wearing sunglasses and a hat with a brim to block ultraviolet sunlight may help to delay cataracts.</p> <p >NIH: National Eye Institute</p>|HPO2016_07_04:A cataract is an opacity or clouding that develops in the crystalline lens of the eye or in its capsule.
