Study type | Observational |
The purpose of this study is to identify whether changes in age-related macular degeneration (AMD) over time as seen with spectral domain optical coherence tomography (SDOCT) imaging, can be used to predict vision loss and the advancement of AMD in people at moderate to high risk for progression.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Primary outcome measures are the percent of eyes developing CNV, mean change in visual acuity, and change in drusen volume, area of GA and photoreceptor layer thickness from SDOCT centered on the fovea. | 2 years and 5 years | ||
Secondary | Drusen area measured from SDOCT versus from color fundus photographs. Mean change in drusen area reproducibility of measurements using these techniques. | 2 years and 5 years | ||
Secondary | Grading of drusen type, presence or absence of fluid, photoreceptor loss or retinal thickening from SDOCT versus from color fundus photographs at each timepoint. | 2 years and 5 years | ||
Secondary | Correlation between SDOCT imaging and autofluorescence imaging and onset of geographic atrophy. | 2 years and 5 years | ||
Secondary | Measurement of area of GA from SDOCT images versus color fundus photos versus AF images. | 2 years and 5 years | ||
Secondary | To evaluate whether the SDOCT outcome measures differ significantly between AREDS 2 patients randomized to different oral supplements in the AREDS2. | 5 years |
