Axial length, myopia progression, and myopic maculopathy in Stickler syndrome
Acta Ophthalmologica, EarlyView.Abstract Purpose We lack knowledge on the potentially progressive nature of and the prevalence of complications to myopia as a characteristic trait of Stickler syndrome. Methods This cross‐sectional study combines ophthalmic examination and medical record data on Danish patients with genetically confirmed Stickler syndrome type 1 (COL2A1) and type 2 ...

Observations key to understanding solar cycles: a review
Frontiers in Astronomy and Space SciencesA paradigm shift is taking place in the conception of solar cycles. In the previous conception, the changing numbers of sunspots over intervals of 9–14 years have been regarded as the fundamental solar cycle although two average 11-year cycles were ...

Search for torsional oscillations in isolated sunspots
, 2017 In this work we seek evidence for global torsional oscillations in alpha sunspots. We have used long time series of continuum intensity and magnetic field vector maps from the Helioseismic and Magnetic Imager (HMI) instrument on board the Solar Dynamics ...

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis
Acta Ophthalmologica, EarlyView.Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Study of Sunspot Penumbra to Umbra Area Ratio using Kodaikanal White-light Digitized Data
, 2019 We study the long-term behaviour of sunspot penumbra to umbra area ratio by analyzing the recently digitized Kodaikanal white-light data (1923-2011). We implement an automatic umbra extraction method and compute the ratio over eight solar cycles (Cycles ...

Acta Ophthalmologica, EarlyView.Abstract Purpose To evaluate long‐term outcomes of anti‐VEGF therapy for nAMD using the Polish Retinal Therapeutic Program Monitoring Registry. Methods The cohort consisted of 63 840 eyes with nAMD qualified for treatment from 2016 to 2022, with follow‐up through 31 October 2023. Long‐term follow‐up (>5 years) was conducted for 7631 eyes.
