What is another name for Reticular pseudodrusen (RPD)?

Reticular pseudodrusen (RPD) is another name for sub-retinal drusenoid deposits. This terminology reflects the appearance and location of these abnormalities, which are found in the subretinal space and are distinct from classic drusen. RPD can be identified on imaging techniques, such as optical coherence tomography (OCT), where they manifest as a specific pattern of elevations under the retina. The designation of “sub-retinal drusenoid deposits” captures both the location and the drusenoid nature of these deposits, emphasizing their relationship to conditions like age-related macular degeneration (AMD). Understanding that RPD is essentially related to drusen but is characterized by its unique pattern helps in identifying and diagnosing it correctly in clinical practice.
