Atrophic Forms (Dry AMD)
Atrophic form of “Dry AMD” is defined by areas of RPE atrophy, often resulting from regression of confluent soft drusen.
Clinical Features and Natural History of AMD on OCT
Despite recent progress, age-related macular degeneration (AMD) remains the leading cause of vision loss in high-income countries, and its incidence appears to be increasing, probably due to longer life span and improved methods of detection.
Polypoidal Choroidal Vasculopathy
Polypoidal choroidal vasculopathy does not constutute part of the classical definition of AMD, but these two en tities have a number of features in common.
Clinical Features and Natural History of AMD
Over recent years, OCT has become an essential part of the examination in routine follow up for AMD to guide clinical practice and analyze the response to treatment. OCT examinations can clearly demonstrate the efficacy of treatment by showing regression or persistence of leakage. Moreover, alterations of the outer retinal layers can also be analyzed.
Classic Choroidal Neovascularization
Since Donald Gass’s pioneering work in 1967, which demonstrated the role of choroidal neovascularization (CNV) in wet (exudative) AMD, visible (classic) CNV, well demarcated and well-defined on fluorescein angiography, has become the most characteristic form of AMD.
