 Novel diagnostic methods, especially optical coherence tomography have widened the understanding of the real time, in vivo status of the different layers.Several papers have shown the relationship between the thickness of the choroidal, Sattler's and Haller's layer between healthy individuals and in people with age-related macular degeneration (AMD).The studies showed significant reduction of layer thickness in relation to the progression of AMD, which may be important in the understanding of choriopathy in the pathophysiology of AMD.
