Know more about cataracts

Cataract is a clouding that develops in the envelope the eye or in the crystalline lens. Derived from the Latin "cataracta" which means "waterfall" and the Greek "kataraktes" which means "to wash". The lens works like a camera lens where the light enters the retina through the Glossary link available on the back of the eye. The lens helps the eye to focus so you can see clearly. Crystalline lens of the eye is made primarily of water and protein. Protein naturally be united so that light can penetrate and Glossary Links cataract is formed when a bond is changed and the protein molecules clumping. This clot will obstruct light to the lens to enter and as we get older, this blob will grow large and thick.

The researchers do not know why the eye's lens changes with age, so that it can cause cataracts. Although not common, cataracts also occur in young people, which is usually caused by trauma to the eye, prescription drugs or chronic health conditions Glossary Links. These have several risk factors that may cause cataracts, such as exposure to ultraviolet light in a long time, side effects such as miotonik disease, dystrophy, diabetes and Wilson's disease. The fetus is exposed to radiation, alcohol, and drug abuse during pregnancy have a high risk factor. Smoking is the most dangerous factor for cataract and use of alcohol Glossary links in the long term can also cause cataracts because of alcohol lead to vitamin deficiency, which deficiency Glossary Links Vitamin C and E have a relationship with the growth of cataracts. Glossary links are also a risk of eye infections are dangerous because Glossary Links tumor can cause changes that are often the growth of cataracts.

Cataracts are categorized into 3 types as the eye lens consists of three components, namely the nucleus or center of the lens, lens or skin periphery, and the membrane that lines the lens or capsule.

• Nuclear Cataracts. Cataracts are common in older patients. This type is grown in the nucleus and it took many years to develop.
• Cataracts Korsial. This type of cataract is formed in the peripheral area or areas of the skin of the lens. Korsial Cataracts are very common in patients with diabetes and if not promptly treated the fungus can spread to the middle of the eye.
• Cataracts Subkapsular. Subkapsular cataracts develop in the area behind the lens and sometimes in the middle. Rapid symptom will occur only in about a period of 1 month.

In the initial phase, will tend to disrupt cataract vision, causing blurred or foggy vision, but this can be overcome by using new glasses, magnification, adequate lighting, strong bifocal or other visual aids. But when symptoms worsen which makes it difficult to perform daily activities such careful driving, reading or working, it will be necessary surgical removal by an ophthalmologist.
