About Cataract

Cataract is one of the most commonly found problems in our eyes. It refers to the development or cloud in the eyes that further hampers the vision. A cataract occurs when proteins in the eye create clumps that avert the lens from processing clear images to the retina. The retina acts by transforming the light that comes through the lens into signals. It transmits the signals to the optic nerve, which carries them to the brain.

Cataract tends to grow slowly and finally interferes with the vision. One might end up having cataracts in one of both the eyes. However, they generally don’t evolve in both the eyes at the same time.

Types of Cataracts

There are different types of cataracts. They’re classified based on where and how they develop in your eye.

  • Nuclear cataracts: - form in the middle of the lens and cause the nucleus, or the center, to become yellow or brown.
  • Cortical cataracts: - refer to wedge-shaped and develop around the edges of the nucleus.
  • Posterior capsular cataracts: - form faster than the other two types and affect the back of the lens.
  • Congenital cataracts: - which remains there since birth or develop during a baby’s first birth year, are rare than age-related cataracts.
  • Secondary cataracts: - are caused by disease or medications. Diseases that are linked with the development of cataracts include glaucoma and diabetes. The use of the steroid prednisone and other medications can sometimes lead to cataracts.
  • Traumatic cataracts: - emerge after an injury to the eye, but it can take many years for this to occure.
  • Radiation cataracts: - can form after a person undergoes radiation treatment for cancer.

Signs of Cataract

Family members of an individual suffering by cataracts in both eyes may come to know that he or she looks not to be seeing as well as earlier. The eye will lookusual to an inexperienced observer, unless the cataract is mature and white. In that situation, the pupil of the eye, which normally appears black, will look grey or white to the observer.

The trained physician will noticereduced visual acuity in the affected eye or eyes. This visual depreciation is not fully rectified by a variation in the glasses. The lens of the eye can be feasiblychecked by an ophthalmologist and the changes in the lens characteristic of cataract can really be seen using a slit lamp, which is an lighting and magnifying instrument used to painlessly observe the structures within the front of the eye, including the lens.

Symptoms of cataract

General symptoms of cataracts include:

  • Blurry vision
  • Trouble seeing at night
  • Seeing colors as faded
  • Augmented sensitivity to glare
  • Halos surrounding lights
  • Dual vision in the affected eye
  • A need for frequent changes in prescription glasses

Causes of cataract

There could be many underlying causes of cataracts. These include:

  • An excess production of oxidants, which are oxygen molecules that have been chemically altered due to normal daily life
  • Smoking
  • Exposure to ultraviolet radiation
  • The extended use of steroids and other medicines
  • Specific diseases, such as diabetes
  • Trauma
  • Radiation therapy

Risk Factors of Cataracts

Risk factors linked to cataracts include:

  • Elderly age
  • Extreme alcohol use
  • Smoking
  • Obesity
  • High blood pressure
  • Previous eye injuries
  • A family history of cataracts
  • Too much sun exposure
  • Diabetes
  • Introduction to radiation from X-rays and cancer treatments

How cataract is diagnosed?

An eye expert will carry out a detailed eye exam to check for cataracts and to analyzethe vision. This will also accompanied by an eye chart test to check the vision at varying distances and tonometry to check the eye pressure.

The most generally conducted tonometry test employs a painless puff of air to flatten the cornea and check the eye pressure. A doctor will also put drops in the eyes to make your pupils bigger. This makes it easier to check the optic nerve and retina at the back of your eye for damage.

Other tests a doctor might conduct include verifyingthe sensitivity to glare and the perception of colors.
