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).

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 ...

Observations of the Formation of a Proto-Spot in a Pre-Existing Field Environment
UniverseBipolar emerging flux regions (EFRs) form active regions (ARs) that generally evolve into a pre-existing magnetic environment in the solar atmosphere. Reconfiguration of the small- and large-scale magnetic connectivities is invoked to explain a plethora ...

Acta Ophthalmologica, EarlyView.Abstract Coats disease diagnosed in adulthood is a rare idiopathic retinal telangiectatic vasculopathy that may differ in phenotype from childhood‐diagnosed cases. This systematic review synthesizes current evidence to characterize its clinical spectrum, imaging features, treatment outcomes and underlying mechanisms, with a focus on immunovascular ...

Acta Ophthalmologica, EarlyView.Abstract Purpose To determine the relationship between the baseline junctional retinal sensitivity measured with microperimetry and the atrophy progression rate in eyes with geographic atrophy (GA) secondary to age‐related macular degeneration. Methods In this prospective cohort study, patients with GA were examined with fundus autofluorescence (FAF ...

Influence of solar activity on the phase of the received signal VLF range
Физика волновых процессов и радиотехнические системы, 2019 The effect of sunspots in the 21 cycle of solar activity on the phase of the received signal on two paths and different frequencies is considered. Experimental data were obtained from the phase of the signals received by the Omega radio navigation system.
