Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

VIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...

COMPARISON BETWEEN AMBLYOPIC AND OTHER NON-AMBLYOPIC EYES IN TERMS OF MACULA AND RETINAL NERVE FIBER LAYER THICKNESS

Sanamed, 2018
Statement of Significance: The prospect of this study is that the macula thickness is reduced in amblyopic eyes and may be a potential diagnostic tool in the future screening of amblyopic eyes.

HSPE1 deficiency underlies the crosstalk between metabolic dysfunction‐associated steatotic liver disease and age‐related macular degeneration

VIEW, EarlyView.
Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...

Anti‐obesity medications and incident ocular outcomes: A systematic review and network meta‐analysis

VIEW, EarlyView.
In this systematic review and network meta‑analysis of 140 studies, anti‑obesity medications showed heterogeneous ocular safety profiles. Semaglutide was associated with higher NAION risk (observational data), whereas dual/multi‑agonists and glucagon‐like peptide‐1 receptor agonists demonstrated favourable glaucoma and overall ocular outcomes ...

Retinal neurovascular alterations are associated with optic radiation microstructure in adrenomyeloneuropathy: A susceptibility separation MRI study

VIEW, EarlyView.
In a cross‐sectional cohort of 104 participants, 7 T susceptibility separation MRI and diffusion imaging were combined with retinal imaging and visual evoked potentials to characterize visual pathway involvement in adrenomyeloneuropathy (AMN). Absolute diamagnetic susceptibility, a myelin‐associated measure, and fractional anisotropy (FA) showed ...

Association between metabolic syndrome, macular structures and retinal vascular calibres in the Northern Finland Birth Cohort Eye Study

Acta Ophthalmologica, EarlyView.
Abstract Purpose We aimed to evaluate the association of metabolic syndrome (MetS) with macular thickness and retinal vascular calibres in the population‐based cohort (Northern Finland Birth Cohort). Methods The population of 2242 individuals was divided into MetS (n = 344) and control groups (n = 1898).
