The impact of systemic long‐term medications for the development of age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract Purpose Age‐related macular degeneration (AMD) is a leading cause of central vision loss in the elderly; however, the systemic factors that modulate its incidence and progression remain unclear. We sought to determine whether long‐term use of systemic medications, including diabetes and antithrombotic medications, corticosteroids and ...

Ultrasound, PET/CT or temporal artery biopsy for giant cell arteritis? A prospective diagnostic accuracy study (the GAME‐study)

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the diagnostic performance of ultrasound, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose positron emission tomography/computed tomography (2‐[18F]FDG PET/CT) and temporal artery biopsy (TAB) in giant cell arteritis (GCA). Methods This was a prospective single‐centre diagnostic accuracy study (ClinicalTrials.gov NCT05248906).

The impacts of high refractive errors on self‐reported visual function and visual concern

Acta Ophthalmologica, EarlyView.
Abstract Purpose To examine the association between refractive errors and self‐reported visual function and visual concern, considering self‐perceived present eyesight, concerns about vision, accomplishing less and limitations in daily activities in an eye‐healthy cohort.

Relationship between the Tilt Angles of Sunspot Groups and the Properties of the Next Solar Cycle

The Astrophysical Journal
Based on the data from the Kodaikanal and Mount Wilson observatories, we investigate the relationships of the tilt angles of sunspot groups, including the mean tilt angle and the tilt-angle scatter, during the declining phase with the parameters of the ...

Three hundred sixty‐degree prophylactic laser retinopexy versus focal laser during rhegmatogenous retinal detachment repair: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare the anatomic, functional and safety outcomes of intra‐operative 360‐degree prophylactic laser retinopexy versus focal laser retinopexy during pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) and to assess the certainty of evidence.

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).

Tilt Angles of Sunspot Groups in Different Latitude Bands and the Amplitude of the Next Solar Cycle

The Astrophysical Journal
In the Babcock–Leighton and Parker dynamo models, the tilt angle of a sunspot group (SG) and the turbulence in the solar convection zone (one widely accepted generation mechanism responsible for the scatter of the tilt angles of SGs around the mean ...

Comparison between variations in solar UV radiation and sunspot parameters with Mg II daily index as a proxy

Physics Open
Solar UV radiation influence the Earth's climate and upper atmosphere. The UV emission from the Sun modulates with the sunspot cycle with an 11-year periodicity.
