Variations in fundus autofluorescence (FAF) in the junctional zone of geographic atrophy (GA) of 149 eyes* with atrophic AMD
| Pattern of increased FAF in the junctional zone of GA | No† | % | |
|---|---|---|---|
| *In 15 eyes of the initially included 164 eyes insufficient FAF image quality did not allow for evaluation of the FAF pattern outside the atrophic patch; frequency data therefore refer to 149 eyes. | |||
| †Six eyes (4.0%) were not grouped into one of these types, because there was no predominant FAF pattern in the junctional zone of GA. | |||
