A Comprehensive Look At Macular Degeneration

  1. 1. A Comprehensive Guide at Macular Degeneration Dr. Quentin Park Park Family Eye Care 9 S. Lincolnway North Aurora, IL 60542 630-844-2500
  2. 2. Table of Contents <ul><li>Overview: What is Macular Degeneration? </li></ul><ul><li>Signs and Symptoms </li></ul><ul><li>Causes </li></ul><ul><li>Risk Factors/Health Tips </li></ul><ul><li>Diagnosis/Treatment </li></ul><ul><li>Recent News and Clinical Study </li></ul><ul><li>Resources/Miscellaneous </li></ul>
  3. 3. Overview: What is Macular Degeneration ? <ul><li>FACT : Macular Degeneration is a incurable eye disease and also the leading cause of blindness for those aged 55 and older in the United States effecting more than 10 million Americans. </li></ul>
  4. 4. <ul><li>Studies have indicated by the year 2025, the </li></ul><ul><li>population of people over age 65 will be six </li></ul><ul><li>times higher than 1990. The reason–“baby </li></ul><ul><li>boomers” are aging and overall life </li></ul><ul><li>expectancy is increasing. Thus, the number </li></ul><ul><li>of cases for macular degeneration will </li></ul><ul><li>increase significantly as the baby boomers </li></ul><ul><li>age. </li></ul>Effects of the Baby Boom
  5. 5. <ul><li>Macular degeneration is caused by the deterioration of the central portion of the retina, the inside back layer of the eye that records the images we see and sends them via the optic nerve from the eye to the brain. </li></ul>
  6. 6. <ul><li>The retina’s central portion, known as the macula is responsible for focusing central vision in the eye, and it controls our ability to read, drive a car, recognize faces or colors, and sees objects in fine detail. </li></ul>
  7. 7. Symptoms: Dry Versus Wet <ul><li>Macular degeneration usually develops gradually and painlessly. The signs and symptoms of the disease may vary, depending on which of the two types of macular degeneration you may have. They are known as dry and wet macular degeneration. </li></ul>
  8. 8. Dry Macular Degeneration Symptoms <ul><li>The need for increasingly bright illumination when reading </li></ul><ul><li>Inc. difficulty adapting to low levels of illumination, such as entering a dimly lit restaurant </li></ul><ul><li>Printed words that appear increasingly blurry </li></ul><ul><li>Colors that appear less bright </li></ul><ul><li>Difficulty recognizing faces </li></ul>
  9. 9. Dry M.D. Symptoms cont’d <ul><li>Gradual increase in the haziness of your overall vision </li></ul><ul><li>Blurred or blindspot in the center of your visual field combined with profound drop in your central vision acuity </li></ul><ul><li>A need to scan your eyes all around an object to provide a more complete image </li></ul>
  10. 10. Wet Mac. Degeneration Symptoms <ul><li>Rapid onset of visual loss </li></ul><ul><li>Visual distortions, such as straight lines appearing wavy or crooked, a doorway or street sign that seems out of whack, objects looking smaller or father away then they should </li></ul><ul><li>Decrease in or loss of central vision </li></ul><ul><li>Central blurry Spot </li></ul>
  11. 11. Causes <ul><li>As said previously, “Macular degeneration is caused by the deterioration of the central portion of the retina (macula), the inside back layer of the eye that records the images we see and sends them via the optic nerve from the eye to the brain .” </li></ul>
  12. 12. Anatomy 101 <ul><li>This central portion of the retina (macula) is made up of densely packed cells known as “ cones and rods” These light-sensitive cells esp. the cones are essential for central vision. Cones are responsible for color, as the rods enable you to see shades of gray. </li></ul>
  13. 13. Anatomy 101 cont’d <ul><li>The choroid layer is a underlying layer of blood vessels that nourish the cones and rods. </li></ul><ul><li>A retinal layer forming the outermost surface is known as RPE (retinal pigment epithelium). It is a critical passageway for nutrients from the choroid to the retina and helps remove waste products retina to choroid. </li></ul>
  14. 14. Chain of Events I <ul><li>As you age, the RPE may deteriorate (atrophy), lose its pigment and become thin which sets off the chain of events. The first thing that goes wrong is the nutrition/waste management cycle between choroid and retina. Secondly, waste deposits then takes form. Thirdly, due to the lack of nutrients, the cones become damaged and can no longer send signals to the optic nerve to your brain, and vision suffers. </li></ul>
  15. 15. <ul><li>Dry Macular Degeneration is the most common form. </li></ul><ul><li>Usually starts in dry form versus wet, and usually affects one eye, but most cases both eventually become involved. </li></ul><ul><li>Many people with early-stage dry macular degeneration may not be bothered with symptoms such as blurred eyesight unless they live to a very old age. </li></ul>Dry Macular Degeneration Facts
  16. 16. Wet Macular Degeneration Facts <ul><li>The wet forms accounts for about 15 </li></ul>
