5 Key Takeaways

• 1

  A case study found a significant decrease in retinal sensitivity associated with iRORA lesions in patients with intermediate age-related macular degeneration.

• 2

  Incomplete retinal pigment epithelium and outer retinal atrophy lesions are identified as precursors to geographic atrophy and disease progression.

• 3

  Adaptive optics scanning light ophthalmoscope microperimetry (AOSLO-MP) was used to assess retinal sensitivity in small areas affected by iRORA lesions.

• 4

  The study included four patients aged 60 to 85, comparing retinal sensitivity between iRORA lesions and control regions using AOSLO-MP and MAIA-MP.

• 5

  AOSLO-MP showed a greater average sensitivity loss of 20.1±4.8 dB at iRORA sites compared to 7.3±3.1 dB with MAIA-MP.
