[The research progress of multimodal imaging for the diagnosis of reticular pseudodrusen]

The emergence and development of multimodal imaging techniques, such as optical coherence tomography, fundus autofluorescence and adaptive optics, make it much easier to differentiate reticular pseudodrusen (RPD) from other fundus lesions. It is of great significance to understand the imaging characteristics of RPD observed with multimodal imaging techniques. This article reviews the formation mechanism and multimodal imaging characteristics of RPD, so as to provide help for better identification of RPD and assessment of the development and prognosis of the disease.
