A cataract is defined as a clouding of lens in the eye where your vision gets blurred. A cataract affects the eyes, when light that passes through the lens prevents a clearly formed image from reaching your retina. The disease is very common and usually develops as your eyes age or due to any injury caused to the tissues that cover your eye's lens.
Types of cataracts:
- Senile Cataract: This is the commonest of all. It is age-related clouding of the lens. It can affect the near or distance vision and can also cause glare and change in glasses power.
- Secondary Cataract: It can be developed after surgery for other eye problems like glaucoma and other health conditions such as diabetes.
- Traumatic Cataract: It can develop many years later after an injury caused to your eye.
- Congenital Cataract: As the term explains, the disease may be inborn or some children might develop it at a later stage which often affects both eyes.
- Radiation Cataract: It can form after you are exposed to some form of radiation.
A cataract surgery involves the extraction or cleaning of the cloudy lens, which is then replaced by a clear artificial lens.
Why does it happen?
There are lens that lies behind our iris and pupil which act much like a camera lens. It helps concentrate light onto the retina at the back of our eye to form a sharply defined image. Besides, the lens also helps our eyes to adjust focus and allows us to see things clearly both far away and up close. The lens is composed of protein and water where the protein is arranged in a manner to keep the lens clear thereby letting light pass through it.
However, as we grow old, some of the protein starts to become thick and cloud a small lens area. This is known as a cataract. With the passage of time, it may inflate and cover more of the lens, making it difficult for us to see.
Besides, there are other causes of cataract such as smoking, addiction of alcohol, prolonged sunlight exposure, to name a few.
When should you opt for a cataract surgery?
Believe it or not, but till date no eye drop or medication has proven to reverse or prevent the formation of a cataract. If a cataract is affecting your nearsightedness or alteration in your prescription, then new prescription eyeglasses may help to better your blurred vision. However, the only treatment for a cataract is the surgical removal of your natural lens. And, most eye doctors recommend this surgery only when the problem becomes severe and starts hampering your day-to-day activities, such as studying or driving at night. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.
Few weeks back my father had a surgery for brain haemmorage, luckily surgery went well and now he is far better but the only problem is" double vision" i. E double images of things that are few metres away. Sometimes he is able to see things properly but sometimes the dual vision comes back. Neurophysician and the eye specialist says that it will recover with time. Should I discuss the case with some other doctors as well or is it a serious or a permanent issue? Just need a second opinion about that. Thank you.
What is amblyopia or lazy eye? Amblyopia is decreased vision in one or both eyes due to abnormal development of vision in infancy or childhood. In amblyopia, there may not be an obvious problem of the eye. Vision loss occurs because nerve pathways between the brain and the eye aren't properly stimulated. The brain, learns to see only blurry images with the amblyopic eye even when glasses are used. As a result, the brain favors one eye, usually due to poor vision in the other eye. Another word for amblyopia is 'lazy eye'. It is the leading cause of vision loss amongst children.
The major causes of Amblyopia are as follows:
- Eye Misalignment: The most basic reason for amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same proportion or direction, the image from the affected eye is turned off by the brain. Only the better eye functions. Double vision is restricted. The persistence of this defect for a prolonged time, makes the eye lose connection with the brain's visual cortex. Amblyopia develops.
- Imbalanced error of refraction: If the refractive blunder of both the eyes is not the same, both eyes can't be in the center at the same time. Amblyopia happens when one eye stays out of the center since it is more myopic, farsighted, or astigmatic than the other. One eye becomes dominant. This results in the neglect of the unfocused eye, which neglects to associate with the mind. Treatment with glasses or contact lenses to adjust the refractive blunder of the eye is required.
- Cloudiness in the visual system: Any kind of obstruction or cloudiness in the normal functioning of the eye tissues can be another reason, which leads to amblyopia. Disorder of any kind which blocks a clear image from being focused is capable of blocking the formation of a clear image on your retina. This may lead to amblyopia. This is perhaps the most severe type of this disease.
How to cure amblyopia?
For treating amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of any disorder of the affected eye such as refractive error, problems in the retina, etc. The goal is to correct the amblyopic eye. The normal eye is usually covered up by a patch, so that only the affected eye can be used for vision. The patching up may continue for weeks, months or years until the best vision gets restored. The improving eye should be maintained well. Spectacles are also prescribed for correction of errors regarding refraction. Eye drops such as atropine are also used for blurring the vision of the good eye. Amblyopia makes you visually impaired. The earliest symptoms must be perceived and acted upon.
