U-Net with Hierarchical Bottleneck Attention for Landmark Detection in Fundus Images of the Degenerated Retina [PDF]
Ophthalmic Medical Image Analysis 2021, 2021 Fundus photography has routinely been used to document the presence and severity of retinal degenerative diseases such as age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy (DR) in clinical practice, for which the fovea and optic disc (OD) are important retinal landmarks.

Molecular Genetics & Genomic Medicine, 2021 Doyne honeycomb retinal dystrophy (DHRD)/malattia leventinese (ML) is an autosomal dominant, progressive retinal disorder characterized by massive central retinal drusen often partly coalescent forming a characteristic honeycomb‐like pattern.

Anomalous angiogenesis in retina [PDF]
Biomedicines 9, 224 (2021), 2021 Age-related macular degeneration (AMD) may cause severe loss of vision or blindness particularly in elderly people. Exudative AMD is characterized by angiogenesis of blood vessels growing from underneath the macula, crossing the blood-retina barrier (that comprise Bruch's membrane, BM, and the retinal pigmentation epithelium RPE), leaking blood and ...

Current Eye Research, 2020 Purpose: A hallmark of age-related macular degeneration is the accumulation of deposits of lipids and proteins, called drusen, in Bruch’s membrane. Several culture models of retinal pigment epithelia (RPE) develop drusen-like deposits.

ROCT-Net: A new ensemble deep convolutional model with improved spatial resolution learning for detecting common diseases from retinal OCT images [PDF]
, 2022 Optical coherence tomography (OCT) imaging is a well-known technology for visualizing retinal layers and helps ophthalmologists to detect possible diseases. Accurate and early diagnosis of common retinal diseases can prevent the patients from suffering critical damages to their vision.

Oman Journal of Ophthalmology, 2023 Optic nerve head (ONH) drusen are acellular calcified concretions. Buried drusen manifests as pseudopapilledema. The compressive effects of ONH drusen can rarely precipitate central retinal vein occlusion (CRVO).

Retinal Angiomatous Proliferation in an Eye with Cuticular Drusen
Case Reports in Ophthalmology, 2015 Purpose: To report the presence of retinal angiomatous proliferation (RAP) in an eye with cuticular drusen detected by fluorescein and indocyanine green angiography by confocal scanning laser ophthalmoscopy and by spectral-domain optical coherence ...

Abundant lipid and protein components of drusen. [PDF]
PLoS ONE, 2010 Drusen are extracellular lesions characteristic of aging and age-related maculopathy, a major retinal disease of the elderly. We determined the relative proportions of lipids and proteins in drusen capped with retinal pigment epithelium (RPE) and in RPE ...
