  • What is a Macular Degeneration?

    Macular degeneration is the leading cause of severe, irreversible vision loss in people over age 60. It occurs when the small central portion of the retina, known as the macula, deteriorates. The retina is the light-sensing nerve tissue at the back of the eye. Because the disease develops as a person ages, it is often referred to as age-related macular degeneration (AMD). Although macular degeneration is almost never a totally blinding condition, it can be a source of significant visual disability.

    There are two main types of age-related macular degeneration:
    Dry form
    The "dry" form of macular degeneration is characterized by the presence of yellow deposits, called drusen, in the macula. A few small drusen may not cause changes in vision; however, as they grow in size and increase in number, they may lead to a dimming or distortion of vision that people find most noticeable when they read.

    Wet form
    The "wet" form of macular degeneration is characterized by the growth of abnormal blood vessels from the choroid underneath the macula. This is called choroidal neovascularization. These blood vessels leak blood and fluid into the retina, causing distortion of vision that makes straight lines look wavy, as well as blind spots and loss of central vision.

  • Treatment
    • 01 Photodynamic Therapy

      A two-step treatment in which a light-sensitive drug (Visudyne) is used to damage the abnormal blood vessels. A doctor injects the drug into the bloodstream to be absorbed by the abnormal blood vessels in the eye. The doctor then shines a cold laser into the eye to activate the drug, damaging the abnormal blood vessels.

    • 02 Intravitreal Injection

      An intravitreal injection involves injecting special medication, commonly anti-vascular endothelial growth factor (anti-VEGF), into the jelly inside your eye. The medication spreads to the retina and other structures of the eye.
      A discussion with your surgeon will allow you to determine if an intravitreal injection is the most suitable option for you. Most patients will have to sit a course of injections before their vision starts to improve

  • How to prevent macular degeneration?

    Prevention is the best method because it does not cure yellow spot lesions for the time being.

    • 1)Do not smoke
    • 2)Choose a healthy diet
    • 3)wear sunglasses to protect your eyes from ultraviolet (UV) light
    • 4)protect your eyes from dust by wearing glasses or goggles
    • 5)Have routine eye exams

    Testing your eyes with an Amsler grid is easy and takes only a few minutes. Here are the basic steps:

    <Amsler check>steps

    • 1)Wearing any glasses you normally use to read, hold the grid 12 to 15 inches away from your face in good light.
    • 2)Cover one eye.
    • 3)Look directly at the center dot with your uncovered eye and keep your eye focused on it.
    • 4)While looking directly at the center dot, notice in your side vision if all grid lines look straight or if any lines or areas look blurry, wavy, dark or blank.
    • 4)Follow the same steps with the other eye.

    If you notice any areas of the grid that appear darker, wavy, blank or blurry, contact your ophthalmologist right away. He or she will check to see what’s going on with your AMD, and begin treatment if appropriate.

    Remember: doing this simple at-home eye test once a day, every day can help save your vision.

    • The Amsler Grid might appear like this to somebody without AMD.

    When gazing at the center black spot, if there is a vacancy or curve in the center of the checkered table, it may be a sign of a defect in the fundus. Please go to the center for detailed examination as soon as possible. Early diagnosis and appropriate treatment can control and slow the progression of the disease, avoiding permanent visual impairment and blindness.
