Case #65 – Subretinal Drusenoid Deposits (SDDs) in AMD – Page 42 of 66

Microperimetry in eyes with SDDs

• Presence of SDDs significantly reduces threshold sensitivity in microperimetry testing²¹
  • Retinal sensitivity in eyes with SDD was lower in all areas of the macula compared to normal controls
  • Mean retinal sensitivity in the superior macula was significantly lower than any other quadrant which is where SDDs first develop

• The number of SDD lesions are associated with reduction of retinal sensitivity²¹

• SDDs have further reduced retinal sensitivity than in eyes with soft drusen²¹
  • While retina sensitivity is significantly reduced in SDDs, photopic visual acuity is generally preserved until conversion to late AMD
