Macular Diseases
Multiple soft, confluent drusen.

  • Considered to be a feature of AMD.
  • Their presence is associated with increased risk of the development of RPE abnormalities, geographic atrophy and choroidal neovascularization.
  • Clinical features:
    • Symptoms: may have decreased vision or metamorphopsia
    • Signs:
      • Defined as greater than 63µm in diameter
      • Vary in size and shape
      • Occasionally seen as confluent structures with indistinct margins
  • Fluorescein angiogram demonstrates:
    • Early hyperfluorescence
    • Either fading of fluorescence or staining of diffuse drusen in the late phase depending on the phospholipid content
    • Pooling of dye within focal detachments of Bruch's membrane
