Cataract

Published Date: 6/17/2023 6:04:37 AM

  • cataract is a dense, cloudy area that forms in the lens of the eye.
  • A cataract begins when proteins in the eye form clumps that prevent the lens from sending clear images to the retina. The retina works by converting the light that comes through the lens into signals.
  • The main symptom is blurry vision. Having cataracts can be like looking through a cloudy window.
  • When a cataract interferes with someone's usual activities, the cloudy lens can be replaced with a clear, artificial lens. This is generally a safe, outpatient procedure.

Causes:

  • Most cataracts develop when aging or injury changes the tissue that makes up your eye's lens.
  • Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery, or medical conditions such as diabetes. Long-term use of steroid medications, too, can cause cataracts to develop.

Symptoms:

Signs and symptoms of cataracts include:

  • Clouded, blurred, or dim vision.
  • Increasing difficulty with vision at night.
  • Sensitivity to light and glare.
  • Need for brighter light for reading and other activities.
  • Seeing "halos" around lights.
  • Frequent changes in eyeglass or contact lens prescription.
  • Fading or yellowing of colors.
  • Double vision in a single eye.

Types of cataracts:

Cataract types include:

  • Cataracts affecting the center of the lens (nuclear cataracts): A nuclear cataract may at first cause more nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and further clouds your vision.
  • As the cataract slowly progresses, the lens may even turn brown. Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color.
  • Cataracts that affect the edges of the lens (cortical cataracts): A cortical cataract begins as whitish, wedge-shaped opacities or streaks on the outer edge of the lens cortex. As it slowly progresses, the streaks extend to the center and interfere with light passing through the center of the lens.
  • Cataracts that affect the back of the lens (posterior subcapsular cataracts): A posterior subcapsular cataract starts as a small, opaque area that usually forms near the back of the lens, right in the path of light. A posterior subcapsular cataract often interferes with your reading vision, reduces your vision in bright light, and causes glare or halos around lights at night. These types of cataracts tend to progress faster than other types do.
  • Cataracts you're born with (congenital cataracts): Some people are born with cataracts or develop them during childhood. These cataracts may be genetic or associated with an intrauterine infection or trauma.

Prevention:

No studies have proved how to prevent cataracts or slow the progression of cataracts. But doctors think several strategies may be helpful, including:

  • Have regular eye examinations: Eye examinations can help detect cataracts and other eye problems at their earliest stages. Ask your doctor how often you should have an eye examination.
  • Quit smoking: Ask your doctor for suggestions about how to stop smoking. Medications, counseling, and other strategies are available to help you.
  • Manage other health problems. Follow your treatment plan if you have diabetes or other medical conditions that can increase your risk of cataracts.
  • Choose a healthy diet that includes plenty of fruits and vegetables: Adding a variety of colorful fruits and vegetables to your diet ensures that you're getting many vitamins and nutrients. Fruits and vegetables have many antioxidants, which help maintain the health of your eyes.
  • Studies haven't proved that antioxidants in pill form can prevent cataracts. But, a large population study recently showed that a healthy diet rich in vitamins and minerals was associated with a reduced risk of developing cataracts. Fruits and vegetables have many proven health benefits and are a safe way to increase the number of minerals and vitamins in your diet.
  • Wear sunglasses: Ultraviolet light from the sun may contribute to the development of cataracts. Wear sunglasses that block ultraviolet B (UVB) rays when you're outdoors.
  • Reduce alcohol use: Excessive alcohol use can increase the risk of cataracts.
