Prevalence, Natural Course, and Prognostic Role of Refractile Drusen in Age-Related Macular Degeneration

Abstract

Refractile drusen are a relative common phenotype in intermediate AMD and appear to confer risk for the development of late AMD. While not all lesions develop late AMD and regression may also occur, distinct subphenotypes as identified by multimodal imaging may not only be visible earlier but also be topographically associated with the risk for GA development. Recognizing the characteristic pattern on multimodal imaging would inform physicians for identification of the lesion and its clinical history.
