Imaging Features That Portend Development of Geographic Atrophy
The past decade has seen interventional studies aiming to slow the progression of disease, but only once GA was already present. In these trials, atrophy was defined on fundus autofluorescence (FAF) imaging, not CFP, with the primary aim being to slow the rate of growth in the area of such lesions. Using FAF to define the area of atrophy allowed more accurate delineation of the lesions than CFP, thus enabling more accurate assessment of areas of atrophy and their change over time.
