Presence of reticular pseudodrusen not tied to progression of intermediate AMD: Study
Australia: The presence of reticular pseudodrusen (RPD) in people with intermediate age-related macular degeneration (AMD) is not significantly associated with an increased risk of developing late AMD, states a recent study. The study appears in the American Journal of Ophthalmology.
The study was done by Zhichao Wu, Ophthalmology, Department of Surgery, The University of Melbourne, Melbourne, Australia, and colleagues with an objective to examine the association between reticular pseudodrusen and progression to late age-related macular degeneration in individuals with intermediate AMD in a prospective cohort study.
The study included 280 eyes from 140 participants with bilateral large drusen who underwent multimodal imaging (MMI), including optical coherence tomography (OCT), near-infrared reflectance (NIR), fundus autofluorescence, and color fundus photography (CFP). They were followed over a period of 36-months at 6-monthly intervals. RPD presence per eye was determined based on either combined MMI criteria, as well as based on each individual imaging modality, and their extent measured on combined OCT and NIR imaging.
