Patients with myeloproliferative neoplasms and high levels of systemic inflammation develop age-related macular degeneration

EClinicalMedicine, 2020
Background: Epidemiological data show that myeloproliferative neoplasms (MPNs) are associated with increased risk of neovascular age-related macular degeneration (AMD). However, knowledge about the retinal findings in these patients is lacking.

Multimodal Imaging and En Face OCT Detection of Calcified Drusen in Eyes with Age-Related Macular Degeneration

Ophthalmology Science, 2022
Purpose: En face OCT imaging was investigated as a method for the detection and monitoring of calcified drusen in eyes with nonexudative age-related macular degeneration (AMD). Design: Retrospective case series of a prospective study.

Retinal complications of optic disc drusen. [PDF]

British Journal of Ophthalmology, 1982
Following reports by Sanders et al. and Wise et al. of optic disc drusen associated with retinal bleeding, an additional 19 cases were studied and followed up for 1 to 10 years (average 5 years). Four of them showed haemorrhages at the optic disc and its borders only, but 15 showed extensive retinopathy with macular involvement.

Epithelial phenotype restoring drugs suppress macular degeneration phenotypes in an iPSC model

Nature Communications, 2021
Age-related macular degeneration is characterized by lipid-rich drusen deposits underneath the retinal pigment epithelium (RPE). Here the authors report an in vitro iPSC-RPE model for AMD that recapitulates drusen and RPE atrophy, and identify two drugs ...

Drusen-like beneath retinal deposits in type II mesangiocapillary glomerulonephritis: a review

Revista Brasileira de Oftalmologia, 2015
The aim of this paper is to do a review of Drusen-like beneath retinal deposits in type II mesangiocapillary glomerulonephritis. Drusenlike beneath retinal deposits in type II mesangiocapillary glomerulonephritis appear to develop at an early age, often ...

Unilateral buried optic nerve head drusen triggering central retinal vein occlusion in young – Discovering an eclipsed entity

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).
