The optical coherence tomography and microperimetry biomarker evaluation in patients with geographic atrophy (OMEGA) study: Geographic atrophy progression in fundus autofluorescence ‐ OMEGA report 3

Acta Ophthalmologica, EarlyView.
Abstract Purpose To measure the progression of geographic atrophy (GA) in subjects with age‐related macular degeneration (AMD) in a natural history study. Methods We analysed fundus autofluorescence (FAF) images using a semiautomatic method (RegionFinder) to quantify the GA area in a monocentric study.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Lactate Accelerates Early Angiogenesis and Bone Regeneration Through Macrophage M1 Polarisation

Cell Proliferation, EarlyView.
During the early stage of bone defect healing, lactate accumulates and contributes to increasing NOD1 expression by stabilising HIF1α that in turn triggers a calcium influx, which ultimately polarises macrophages towards the M1 phenotype and accelerates vascularisation of endothelial cells.

Abnormal Glycaemic Fluctuations Associated With Early Microvascular Changes in the Retina and Choroid of Nondiabetic Adults

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims To evaluate the association between continuous glucose monitoring (CGM)‐derived glycaemic variability indicators and early microvascular changes of the retina and choroid in nondiabetic individuals. Materials and Methods Community‐based individuals at high risk for type 2 diabetes (T2DM) underwent detailed assessments including oral ...

Abstract: OCT-OCTA Segmentation

, 2018
In this work, a novel paradigm for segmenting optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) is presented [1]. Since it uses OCT and OCTA information jointly it is called “OCT-OCTA segmentation” and its usefulness ...

Optical coherence tomography angiography (OCTA) as a new diagnostic tool in uveitis [PDF]

, 2019
Background: The broad spectrum of uveitis disorders requires a multimodal imaging approach in the daily practice of an ophthalmologist. As inflammatory conditions, they have in common an alteration in leukocyte migration.
