The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Solar Cycle Prediction Using a Temporal Convolutional Network Deep-learning Model with a One-step Pattern

The Astrophysical Journal Supplement Series
The human living environment is influenced by intense solar activity that exhibits periodicity and regularity. Although many deep-learning models are currently used for solar cycle prediction, most of them are based on a multistep pattern.

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).

Chinese Sunspot Drawings and Their Digitization. VIII. Release of a Machine-readable Parameters Catalog

The Astrophysical Journal Supplement Series
We present a systematically revised and manually verified digital catalog of historical sunspot drawing observations from Chinese observatories, encompassing sunspot number, sunspot group number (GN), and sunspot area measurements.

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.

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.

Calibration of Sunspot Numbers

, 2010
Waldmeier [1971] found a very tight relationship between the F10.7 solar radio flux and the sunspot number and suggested using the flux for an objective calibration of the sunspot number. He suggested that if this relationship changed later on, the sunspot number should be re-calibrated, assuming that the calibration must have drifted with time.

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).
