The effect of rhegmatogenous retinal detachment on retinal oxygenation

Acta Ophthalmologica, EarlyView.
Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.

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

Timing and duration of glucagon‐like peptide‐1 receptor agonist use and risk of nonarteritic anterior ischaemic optic neuropathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the association between glucagon‐like peptide‐1 receptor agonist (GLP‐1RA) use and nonarteritic anterior ischaemic optic neuropathy (NAION) in type 2 diabetes, examining treatment recency and cumulative duration. Methods This nationwide registry‐based nested case–control study utilizedz Danish health registries (1996 ...

Visual acuity is reduced with increasing central retinal thickness, but also with higher age and female sex in diabetic macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Introduction The increasing number of patients with diabetes has increased the incidence of diabetic macular oedema (DME) with the accompanying risk of developing visual loss. The purpose of the present study was to describe the contributions of increased central retinal thickness (CRT) and other risk factors to the reduction in visual acuity ...

Exploring the effect of gestational diabetes mellitus on retinal vascular morphology by PKSEA-Net

Frontiers in Cell and Developmental Biology
BackgroundGestational diabetes mellitus (GDM) is a temporary metabolic disorder in which small retinal vessels may have experience subtle changes before clinical lesions of the fundus retina appear.

En face localization of retinal telangiectatic capillaries using OCT compared with ICG angiography in chronic vascular macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinal telangiectatic capillaries (TelCaps) are microvascular abnormalities associated with chronic vascular macular oedema and suboptimal response to intravitreal therapy. Targeted laser photocoagulation is beneficial but requires precise localization using indocyanine green angiography (ICG‐A), the reference standard. However, ICG‐A

Macular telangiectasia type 2 genetic risk variants associated with clinical characteristics in the Slovenian cohort

Acta Ophthalmologica, EarlyView.
Abstract Purpose Early diagnosis of macular telangiectasia type 2 (MacTel) remains challenging, and the contribution of genetic variation to its clinical heterogeneity is unclear. This study investigated associations between MacTel risk variants and clinical characteristics in a Slovenian cohort.

Inter‐eye microvascular asymmetry across stages of diabetic retinopathy: An OCT angiography study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate inter‐eye asymmetry in macular microvascular parameters across different stages of diabetic retinopathy (DR) using OCT angiography, and to explore the associations with clinical factors. Methods This cross sectional study included 442 eyes of 221 patients with diabetes mellitus type 2. Central subfield thickness (CST), area

CD93—An emerging vascular target in cancer therapy

British Journal of Pharmacology, EarlyView.
Abstract CD93 is a single‐pass transmembrane glycoprotein that belongs to the C‐type lectin domain group XIV family of proteins. Although it is known to be expressed in other cell types, namely, in some subsets of immune cells, CD93 is primarily expressed on endothelial cells, where it acts as a crucial regulator of angiogenesis.
