Glaucoma A cataract is a cloudy or opaque area in the normally clear lens of the eye. Depending upon its size and location, it can interfere with normal vision. Most cataracts develop in people over age 55, but they occasionally occur in infants and young children. Usually cataracts develop in both eyes, but one may be worse than the other. The lens is located inside the eye behind the iris, the colored part of the eye.

Cataract Surgery and Glaucoma A Natural Process. Again, cataracts are a natural process and, thus far, an unavoidable part of aging. As we age the chances of having a cataract increases. For example, it is estimated that in the U.S. less than 4% of men and 10% of women between the ages of 55 and 64 years have visually significant cataracts. Between the ages of 65 and 74 years, 14% of men and 24% of women experience cataracts.

Dogs can be born with cataracts or can develop them at an early age, as I suspect is the case with Bernie.

Are There Different Types of Cataracts? By Tina D. Turner, M.D. There are three primary types of age-related cataracts: nuclear sclerotic, cortical, and posterior subcapsular. As a person ages, any one type, or a combination of any of these three types, can develop over time. This is the most common type of age-related cataract, caused primarily by the hardening and yellowing of the lens over time.

Top 40 Doctor insights on: Cortical Cataract Symptoms Cataract types: A cataract is a clouding of the natural lens of the eye. Most people will develop a diffuse clouding of the lens with age.

In many cases, cataracts are age-related, appearing first when a person is in his or her 40s or 50s, but not affecting vision until after age 60. In other cases, cataracts may be related to eye trauma, long-term diabetes, corticosteroid medications or radiation treatments.
