How a cataract forms?
Cataracts forms behind the colored part of a human eye that is “iris”, as a person ages, the lenses in a person eye becomes less flexible, less transparent and thicker. As a person grows old, growing age and other problems rises and causes lenses to break and clump together, clouding small areas with lens. And as the cataract develops the clouding becomes deeper and deeper. A cataract scatters and blocks the light as it is pass through lens, preventing light or image to reach your retina. As a result of which you become blind.
Types of cataracts?
Nuclear cataracts: A nuclear cataract may fool you as in the beginning your vision becomes more clear but slowly it starts developing and disturbs your vision and the lens become more yellow with time. And as the cataract develops the lens may turn brown in color too.
Cortical cataract: This type of cataract begins with the edges of the lens and it appears whitish in beginning. As it starts to grow, it covers the middle area of the eye and block the vision.
Posterior Sub-capsular cataract: It usually begins to form behind the lens, it disturbs your reading vision. This type of cataract develops more faster than the other types.
Congenital cataract: Some people are born with this type of cataract, or it slowly develops with growing age. These cataracts may be genetics, or associated with an intrauterine infection or trauma. These kind of cataracts may grow because of the following reason:
- Myotonic dystrophy
- Neurofibromatosis type 2 and,
Causes of Cataracts
A person age is the most reason behind developing cataract. With time lens proteins denature and degrade which is natural as do other body parts. And this process is further triggered by diseases such as the following:
- Diabetes Mellitus,
- And hypertension.
The environment factors are the following, yes the environment factors:
- Ultra violet light.
Blunt trauma causes swelling, thickening, and whitening of the lens. In some traumas, swelling normally resolves with time, but the white color can remain for a long time. The damage causes fluid from other parts of the eye to rapidly enter the lens which further leads to swelling and whitening of the eyes. Cataracts can also develop in the case of electrical injuries, in about 0.7 to 0.8 percent of the cases.
One of the main causes behind cataracts is radiation, ultra violet rays, but wearing sun glasses from an early age can reduce the process or affect of it. You will be a little shocked to know but microwave radiation can also cause cataracts.
The development of cataract in an early can be due to a particular syndrome. These syndromes are the following:
- Single-gene disorder include Alport’s syndrome,
- Conradi’s syndrome,
- Myotonic syndrome,
- Lowe syndrome,
- And, Oculocerebrorenal syndrome.
The skin and the lens have the same embryological origin and can be affected by other diseases. Person who have Atopic dermatitis and Eczema are more prone to develop shield ulcers cataract.
Smoking and Alcohol
It has been shown that smoking doubles the chance of getting nuclear sclerotic cataract and triple the rate of posterior subcapsular cataract.
Low intake of vitamin C
This is also a main reason, low intake of vitamin C and serum levels, can cause cataracts.
Some medicines can also cause cataract, such as inhaled corticosteroids, people with schizophrenia and antipshychotic.
- Fabry’s disease,
- Wilson’s disease,
- Congenital disease,
Signs and Symptoms of Cataract
Both signs and symptoms of cataract depends on the type of the cataract, People who are suffering from Nuclear sclerotic or brunescent cataracts can and often notice a reduction of vision. Those suffering from posterior subcapsular cataract usually complain about glare as their main problem.
How can cataract be prevented?
A person can stop smoking and drinking to prevent cataracts. Although there are no scientific prove which have shown to prevent cataract. Wearing sunglasses is a great way to prevent it.
Treatment of cataract
Cataract can be removed at any stage through surgery. Surgery is performed after giving or using local anaesthesia. Nine patients out of ten can get their vision back.
Phacoemulsification is the most widely used cataract surgery.
How to Dissolve Cataract Without Surgery
There are many eye drops available in the market which can dissolve the cataract in the eyes but the real problem is that the ophthalmologists who treat cataract with surgery charges high fees for operation of cataract. Therefore, they don’t tell public about this marvelous innovation because they will lose their profits. Therefore, it is very essential to get a good ophthalmologist so that he can give a good advice as to whether a surgery is needed or eye drops are enough to cure it.
