Brief Summary:
The investigators wish to better understand the role of the choriocapillaris (CC) in the formation and progression of non-exudative in age related macular degeneration (armd) by imaging the retinal pigment epithelium (rpe) and the choroidal microvasculature and by studying their inter-dependence to determine if the loss of the CC could prove useful as an anatomic clinical trial endpoint in future drug trials.

Condition or disease Intervention/treatment
Dry Macular Degeneration Device: SS-OCT imaging

Detailed Description:
This is a longitudinal observational study where the investigators will look at 450 subjects, 200 with intermediate AMD in at least one eye, or with AMD in one eye, either early or intermediate, and with late AMD (exudative) in the other eye, and 250 subjects with nGA or GA in at least one eye.

Group/Cohort Intervention/treatment
Cohort 1 'IMPACT Cohort'
Subjects with intermediate AMD in both eyes, and at least one eye with a drusen volume in the central 3 mm circle centered on the fovea of at least 0.02mm3 in the absence of GA or nGA as diagnosed with OCT en face imaging OR subjects with AMD (early or intermediate) diagnosed in one eye and exudative AMD diagnosed in the fellow eye will undergo SS-OCT imaging every 3 months for 2 years
Device: SS-OCT imaging
All subjects will undergo retinal imaging using the Zeiss PlexElite SS-OCT, a non-contact, non-invasive ocular imaging instrument
Other Names:
  • Zeiss PlexElite
  • PlexElite 9000
  • Swept Source OCT
  • Optical Coherence Tomography Angiography

Cohort 2 'SWAGGER Cohort'
Subjects with GA or nGA secondary to AMD that is at least the size of a large druse (125 microns in diameter; 0.05 mm2) and no greater than 7 disc areas (17 mm2) in at least one eye will undergo SS-OCT imaging every 3 months for 2 years
Device: SS-OCT imaging
All subjects will undergo retinal imaging using the Zeiss PlexElite SS-OCT, a non-contact, non-invasive ocular imaging instrument
Other Names:
  • Zeiss PlexElite
  • PlexElite 9000
  • Swept Source OCT
  • Optical Coherence Tomography Angiography

Cohort 3
Subjects with GA enrolled in another trial
Device: SS-OCT imaging
All subjects will undergo retinal imaging using the Zeiss PlexElite SS-OCT, a non-contact, non-invasive ocular imaging instrument
Other Names:
  • Zeiss PlexElite
  • PlexElite 9000
  • Swept Source OCT
  • Optical Coherence Tomography Angiography




Primary Outcome Measures :
  1. Change in Choroidal Perfusion Deficits at 1 year compared to Baseline [ Time Frame: 1 year time point ]
    Assessment of Choriocapillaris perfusion


Secondary Outcome Measures :
  1. Pre-existing sub-clinical Macular Neovascularization (MNV) [ Time Frame: 1 year and 2-year time points ]
    Presence of abnormal new vessels arising from the Choroid

  2. Automated Drusen Volume measurements [ Time Frame: 1 year and 2-year time points ]
    Compare the automated measurements of drusen volume using the Zeiss algorithm with manual measurements by trained readers

  3. Automated GA measurements [ Time Frame: 1 year and 2-year time points ]
    Compare the automated measurements of GA area using the Zeiss algorithm with manual measurements by trained readers

  4. Structural OCT markers and Genetic Markers [ Time Frame: 1 year and 2-year time points ]
    Correlate structural markers on SS-OCT/OCTA with genetic markers of disease


Biospecimen Retention:   Samples With DNA
At baseline or follow up, an optional blood sample for future exploratory genetics analysis will be collected
