Cataract

Tuesday, August 2, 2011

Cataract is the clouding that occurs on some or all parts of the eye lens. The cause of cataracts is due to aging, accident, disruption of metabolism due to prolonged illness, congenital or even poisoning. Symptoms experienced by people with cataract is a cloudy vision, glare, when viewed with the aid of light on the pupil will look cloudy.

Cataracts were divided memjadi several types:
Senile Cataract (aging).Cataracts that arise after age 40 years, the process is not known, allegedly due to aging.

Congenital cataracts.
Cataracts that arise in the womb or arise after birth, usually due to infection, and metabolic abnormalities at the time of formation of the fetus. Congenital cataracts are often caused by maternal infection during pregnancy, especially in the first 3 months of pregnancy.

Cataract Traumatika. 

Cataracts that can strike all ages, usually because of post-traumatic both sharp and blunt on the eye especially on the lens.

Cataract Complicated, is arising post-cataract eye infections.


Cataracts Handling

Cataract surgery can be overcome by making the lens is cloudy. There are several surgical techniques performed at the Hospital, namely: Operating with large slices with conventional sutures and a small incision without sutures lens is removed by means of Phaceomulsifikasi (small incision surgery).

Selection of surgical technique depends on the eye lens of violence. After the cataract lens is taken, the patient can only count fingers at a distance of 1 meter, unless the patient replaced the lens.

Replacement lenses there are two ways:

• Patients after surgery were positive eyeglasses or contact lenses for approximately 10 diopters.

• Patients with a lens mounted at the same time conducted operations planting, the advantage is a patient after surgery the patient can immediately see the obvious, do not need to wear very thick glasses, the patient remained wide field of vision and light distortion can be eliminated.

Abnormalities Refraction: Myopia When Viewing Distance Objects and Reading

The eyes are one of the senses of the human body that serves for vision. Although its function is essential for human life, but often less unnoticed, so many diseases that attack the eye is not treated properly and cause impaired vision to blindness.

Vision problems most commonly experienced are myopic, may be a myopic view distant objects, nearsightedness see objects at close range,
myopic when it is reading that is usually experienced by those aged above 40 years of age or a mixture of myopia and myopic view distant objects when you're reading.
All types of myopic eyes was essentially a distraction to focus the image object being viewed or refractive disorders (Ametropia).

Abnormalities of refraction (Ametropia) is a distortion parallel rays reflected from objects that we see, where the rays are refracted by the lens of the eye in a relaxed state is not exactly on the retina. Abnormalities of refraction can be overcome by using glasses or contact lenses.
If you have complaints myopic in your eyes, consult your eye doctor or optical medical personnel to be given advice and solutions to solve your problem. It is recommended also for eyes examined at least once a year, so that your complaint can be treated early and prevent more severe disease for the disorder - a disorder that occurs in the eye that can interfere with the activity to cause blindness. Routine eye examinations can be performed more frequently in those with a family history that has a refraction disorders, high blood pressure, diabetes or cataracts.

Various kinds of abnormalities of Refraction

Eye Myopia
Often said to be nearsighted, namely the decrease in distant visual acuity when compared with normal people. The cause of myopia is the axis of the eyeball is too long or the refractive power of the eye lens is too strong. Complaints are usually felt by people with myopia are blurred in seeing distant objects, the eyes get tired, dizzy and often watery. This disorder can be corrected with the glass minus / concave.

Hipermetrop eye.
Namely patients with this disorder complain of blurred vision acuity both near and far. Cause Hipermetrop is the axis of the eyeball is too short or the refractive power of the eye lens is too weak. Complaints are usually felt by people hipermetrop is opaque in to see objects near and far, eye fatigue, dizziness and frequent watering. This disorder can be corrected with lenses plus / convex. This situation arises in many children, especially children who were born prematurely, with age then there is the growth of the eyeball so that the size of the correction lens decreases.

Asigmatisme eye.
Asigmatisme eye or eyes is also often called cylindris ie visual acuity abnormalities are caused because people can not see as clearly shown in one plane so that the patient usually feels shaded in seeing distant objects. This is because not the same as the curvature of the cornea and corneal surface is uneven. Asigmatisme eye can be corrected with lenses cylindris.

Handling

• There are various handling: Namely with the use of conventional eyeglasses, prescription eyeglasses should be given the maximum according to the required size is used to stimulate the nerves of vision.
•  With the use of contact lenses, contact lenses with the use of more patients are required to maintain cleanliness.
• With Refractive surgery (Lasik) is by thinning or incision in the cornea to reduce the thickness, is generally performed on patients has been outstanding for more than 22 years, assuming the shape of the eyeball has a maximum and cooperative patient.
• With clear lens surgery, performed in patients with very high miop that does not allow in doing Lasik, or it could be planted in front of the lens iris.

Eyes and Computers

What is the effect on the eye if it's too long to see a computer monitor?

Computer equipment is always used in every office work, factory, teaching and learning activities and even homes are now already provided computers, so many people have to work in front of computer monitor all day. To be able to see
clearly and berakomodasi, our eyes are equipped with three external muscles that regulate the movement of the eyeball. These three muscles is precisely what will work hard when you work for a computer in de pan. When you are too tired, muscle - eye muscles will decrease its strength and ability to focus the eyes were going to decline. It is not possible you will complain of headaches, blurred vision permanently so that must wear glasses, or even increase the size of the minus / plus your glasses.

Here are some tips to overcome fatigue and eye strain while working in front of the monitor.

• Give a break to taste regularly, although only by simply closing his eyes for several minutes, even before your eyes feel tired. Do not ever rubbed your eyes, frequently flashing. It can reduce tension and keep your eyes stay moist and cool. If you are too old to see at close range, switch your view towards the distant. Do it for a few minutes every 30 minutes.

• Notice the lighting in your workspace. Do not work in a room that is too bright and blinding. Use blinds to adjust light from the window. Put the overhead lights. Avoid staring at the light directly. Conversely, do not also work in a room that is too dark or dim. Try to keep your room bright enough agarmata you do not work hard.

• Use the monitor glass filter to reduce glare and radiation emitted by the monitor. Talk to your computer equipment vendor to get a good filter and can reduce radiation ipengaruh, not just dim light of the monitor. Check if your monitor is still working fine. When a picture is looking increasingly dim, or uncomfortable for your eyes, then it's time to repair or replace your computer monitor. Better to change the monitor rather than letting your eyes troubled. Frequently monitor clean of dust and dirt that interfere with the display.

• If you must work with a copy or read the paper, then place the paperwork is in close balance with your monitor. This is so that you do not need to go back and forth to focus the view to read your paper work, after reading on the screen.

• Place the monitor screen in such a way as to form an angle between 10-15 degrees from the straight line with your views. This is in addition to avoid tiring your eyes, also keeping your shoulders and your neck is quite comfortable to work.

• If you must edit the papers in front of the computer, make sure the size or "font" letters that you use big enough. Do not force your eyes to read small letters on the monitor. Your eye is not a microscope for the writing on the screen monitor. Use the facility to zoom in or adjust the display image on your monitor. When you've finished editing or reading, you can return the font to its original position.

• If you use glasses or contact lenses and you have to work all day in front of the monitor, it is better to consult your eye doctor or optical so you can get glasses that fit. Both the size of the lens and frame. When you get tired use the spectacles, uninstall it. Glasses can make eyes tired. Occasionally let your eyes see is free. However, soon you wear glasses if feels compelled to wear. Do not force your eyes to see without the aid of your glasses.

Diabetes and Your Vision

One factor is the influence of vision problems including health problems such as diabetes disorders, impaired vision because of diabetes usually causes cloudy eye lens, eye ball fluid viscosity changing where patients experience a fairly drastic measure changes in tempo or a fast enough time.

Suppose today is known to have diabetes -2.00 refraksinya sizes up to level 200 then within 3 days when his blood sugar level drops to the level of 150 is usually the size of the refraction of a drastic change will be uncertain, for example a +1.00 or -0.50,

We recommend that if you have diabetes check with your diabetes level, and look for a fairly stable level of diabetes, then check your vision, so if you make any new glasses then ukuranya not easily changed. Other disorders caused by disturbances of diabetes increased eye pressure that is commonly called Glaucoma, therefore penederita feel pain in the eye accompanied by blurred vision in disorders of the prolonged diabetes can cause blindness, caused by bleeding in the retina or the emergence of new blood vessels on the surface of the retina.

Exposure to UV rays Dangers Of Eye

Did you know that the sun emits UV rays can be harmful to your eyes? UV rays are categorized into 3 groups
namely

UV C rays with a wavelength of 200-280 nanometer. Energy levels of UV radiation on this type is the most dangerous. UV-C rays from the sun mostly been absorbed by the ozone layer in Atmospher (Stratosphere). UV-C light is also produced by welding so that when performing this activity must use the correct protective.

UV B rays with a wave length of 280-315 nanometer. Energy levels at most cause damage to the body (skin looks red and sore) and eye (keratitis: Inflammation of the cornea with the pain was - and it usually causes severe visual impairment)

UV A rays with a wavelength of 315 Nanometer -380. With the level of the lowest-energy radiation are potentially harmful to the eyes if exposed in the long run such as cataracts. You should use a sunglass to protect the eyes if too often baraktifitas under the sun.

Foods for Eye Health

Eyes are the five senses is very important / essential. Conceivably, if we have eye damage or blindness, we can not enjoy and feel how beautiful this universe.

In fact we often forget to make eye care, but as parts of the body, the eyes may be affected by the disorder or health problems. Disorder-disorder can be caused by air is not clean or polluted, solar radiation, radiation from too long in front of computers, and other disturbances.

Studies conducted by the Eye Disease Prevalence Research Group (2004) estimates that by 2020 the number of people with eye diseases and blindness in the world will reach 55 million. The study also mentions that the eye disease and blindness will increase, especially for those who have aged over 65 years. A person aged 80 years and over who is 8% of the total population, suffered blindness as much as 69%.

Health problems in a common eye problem is the decline in vision function, red-eye symptoms without any decrease in vision function, and red eye with decreased visual function. Until now, eye disease that affects many are cataract, glaucoma, and infection.

Along with increased attention and knowledge of the influence of nutrition on health, especially the health of the eye causes the rapid market growth of healthcare products, food, medicine, health foods, medical drugs, food supplements, health supplements, herbal remedies, natural cure eye. Most of the products for eye health which is now marketed in the form of supplements, food drug, health food, medical drugs, food supplements, health supplements, herbal medicine, natural medicine. In addition to antioxidant compounds (vitamins A, C, and E) that had previously been known to improve eye health, other compounds such as lutein, zeaxanthin, and astaxanthin, recently known as a compound that can improve the health of the eye.

Lutein, a yellow carotenoid family of compounds are found in many green vegetables. Lutein in the macula and are believed to protect the eyes from oxidative damage by ultraviolet light radiation (UV).

Macula is in the middle of the retina and directly adjacent to the eyepiece. Macula is a small area containing millions of cells that help produce sharp eyesight to read or see objects clearly.

Other carotenoid compounds present in the macula is is zeaxanthin, which are known to provide benefits for eye health.

Research conducted by Chitchumroonchokchai and colleagues in 2004 from Ohio State University, showed that lutein and zeaxanthin may protect human lens cells from UV exposure, which is the main cause of cataracts. In addition, they compared the antioxidant activity of lutein and zeaxanthin as vitamin E. The results showed that lutein and zeaxanthin showed 10 times higher activity than vitamin E in protecting the lens cells from damage caused by ultraviolet light.

The same year also conducted research by Neuringer and colleagues, demonstrated the ability of lutein and zeaxanthin in improving eye health. While testing on animals, sponsored by DSM Nutritional Products Switzerland, showed that the supplementation or the addition of lutein and zeaxanthin increase the activity of antioxidants in the blood.

Group of other carotenoid compounds that actually has the ability to protect the macula from UV exposure is astaxanthin. Guerin et al. (2003) mentions that the ability of antioxidants and anti-inflammatory compounds astaxanthin can give the effect of eye protection from UV rays.

Until now, the antioxidant activity of compounds lutein, zeaxanthin, and astaxanthin provide answers mechanisms increase in eye health. Free radicals from UV light or air contamination, into the eye resulted in the oxidation of molecules susceptible to the eyepiece.
