Multispectral pattern recognition measures change in drusen area in age-related macular degeneration with high congruency to expert graders

open access: yesScientific Reports, 2022
Drusen are a hallmark lesion of age-related macular degeneration (AMD) and changes in their area and/or volume are strongly associated with disease progression. Assessment of longitudinal change in drusen size in clinical practice however is limited to a

Soft Drusen in Age-Related Macular Degeneration: Biology and Targeting Via the Oil Spill Strategies

open access: yesInvestigative Ophthalmology and Visual Science, 2018
AMD is a major cause of legal blindness in older adults approachable through multidisciplinary research involving human tissues and patients. AMD is a vascular-metabolic-inflammatory disease, in which two sets of extracellular deposits, soft drusen/basal

Retinal drusen in glomerulonephritis with or without immune deposits suggest systemic complement activation in disease pathogenesis

open access: yesScientific Reports, 2022
Retinal drusen are characteristic of macular degeneration and complement activation, but also occur in C3, lupus and IgA nephropathy. This cross-sectional observational study compared drusen counts in different forms of glomerulonephritis.

Biological effects of cigarette smoke in cultured human retinal pigment epithelial cells. [PDF]

open access: yes, 2012
The goal of the present study was to determine whether treatment with cigarette smoke extract (CSE) induces cell loss, cellular senescence, and extracellular matrix (ECM) synthesis in primary human retinal pigment epithelial (RPE) cells. Primary cultured

Macular neovascularization in eyes with pachydrusen

open access: yesScientific Reports, 2021
The natural history and clinical significance of pachydrusen is unclear. This study aims to compare the longitudinal changes of eyes with pachydrusen and soft drusen and progression to exudative macular neovascularisation (MNV). Patients with a diagnosis

Ex Vivo Hyperspectral Autofluorescence Imaging and Localization of Fluorophores in Human Eyes with Age-Related Macular Degeneration

open access: yesVision, 2018
To characterize fluorophore signals from drusen and retinal pigment epithelium (RPE) and their changes in age related macular degeneration (AMD), the authors describe advances in ex vivo hyperspectral autofluorescence (AF) imaging of human eye tissue ...

Prevalence and histopathological signatures of optic disc drusen based on microscopy of 1713 enucleated eyes

open access: yesActa ophthalmologica, 2020
Optic disc drusen (ODD) are calcified optic nerve head deposits. Objectives of this study were to examine the prevalence of ODD in eyes removed by enucleation and to describe related histopathological signatures of ODD and surrounding tissues.

In Vivo Multimodal Imaging of Drusenoid Lesions in Rhesus Macaques. [PDF]

open access: yes, 2017
Nonhuman primates are the only mammals to possess a true macula similar to humans, and spontaneously develop drusenoid lesions which are hallmarks of age-related macular degeneration (AMD).
