The role of optical coherence tomography angiography in reticular pseudodrusen

Photodiagnosis and Photodynamic Therapy, 2021
To investigate the changes in retinal and choriocapillaris vessel density (VD) in patients effected by early age-related macular degeneration (AMD) and reticular pseudodrusen (RPD), using Optical Coherence Tomography Angiography (OCTA).A total of seventy-eight eyes of 78 patients (43 male, 35 female, mean age 72.61 ± 5.15) with non-neovascular AMD (38 ...

Incidence and Risk Factors of Reticular Pseudodrusen Using Multimodal Imaging. [PDF]

JAMA Ophthalmol, 2020
Although retinal multimodal imaging is needed for diagnosing reticular pseudodrusen (RPD), the incidence of RPD in the general population typically has been assessed only using fundus photographs, which may underestimate their incidence.To describe the incidence of RPD using retinal color photographs, spectral-domain optical coherence tomography scans,

Visualizing and understanding inherent features in SD‐OCT for the progression of age‐related macular degeneration using deconvolutional neural networks

Applied AI Letters, Volume 1, Issue 1, October 2020., 2020
Abstract To develop a convolutional neural network visualization strategy so that optical coherence tomography (OCT) features contributing to the evolution of age‐related macular degeneration (AMD) can be better determined. We have trained a U‐Net model to utilize baseline OCT to predict the progression of geographic atrophy (GA), a late stage ...

Risk factors for progression of age‐related macular degeneration

Ophthalmic and Physiological Optics, Volume 40, Issue 2, Page 140-170, March 2020., 2020
Abstract Purpose Age‐related macular degeneration (AMD) is a degenerative disease of the macula, often leading to progressive vision loss. The rate of disease progression can vary among individuals and has been associated with multiple risk factors. In this review, we provide an overview of the current literature investigating phenotypic, demographic ...

Multimodal Retinal Image Analysis via Deep Learning for the Diagnosis of Intermediate Dry Age‐Related Macular Degeneration: A Feasibility Study

Journal of Ophthalmology, Volume 2020, Issue 1, 2020., 2020
Background and Objective. To determine if using a multi‐input deep learning approach in the image analysis of optical coherence tomography (OCT), OCT angiography (OCT‐A), and colour fundus photographs increases the accuracy of a CNN to diagnose intermediate dry age‐related macular degeneration (AMD). Patients and Methods. Seventy‐five participants were

Evaluation of coronary artery disease as a risk factor for reticular pseudodrusen [PDF]

British Journal of Ophthalmology, 2017
PurposeReticular pseudodrusen (RPD) are a risk factor for late age-related macular degeneration (AMD). Associations between RPD and coronary artery disease (CAD) have been reported from small case–control studies. This study investigated the association of RPD within a predominantly CAD cohort.MethodsA subgroup of subjects from a multicentre randomised
