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 ...

The effect of rhegmatogenous retinal detachment on retinal oxygenation
Acta Ophthalmologica, EarlyView.Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.

Frontiers in Astronomy and Space Sciences, 2018 To make transformational scientific progress with the space weather enterprise the Sun, Earth, and heliosphere must be studied as a coupled system, comprehensively. Rapid advances were made in the study, and forecasting, of terrestrial meteorology half a

Radial outer retina reflectivity (RORR) sign in LAMP2‐associated retinopathy
Acta Ophthalmologica, EarlyView.Abstract Purpose To describe the radial outer retina reflectivity (RORR) sign in patients carrying pathogenic variants in the X‐linked lysosome‐associated membrane protein‐2 (LAMP2) gene and to review the histologic characteristics of LAMP2 expression in the human retina.

Retinal dystrophies simulating geographic atrophy: A diagnostic challenge
Acta Ophthalmologica, EarlyView.Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting

Three years of ocular proton therapy in the Netherlands, clinical results
Acta Ophthalmologica, EarlyView.Abstract Purpose Uveal melanoma (UM) is a rare cancer with rising number of diagnosis (143 diagnoses in 1990 to 226 in 2023) in the Netherlands. Most patients are treated locally with Ruthenium‐106 brachytherapy (±102/year). Patients were referred for proton therapy (PT) to Switzerland in the past, but PT is available in the Netherlands from January ...

Where are Sunspots? The Practical Method of Galileo as an example of Mental Model
Zagadnienia Filozoficzne w Nauce, 2019 After the publication of Sidereus Nuncius, in the controversy with Ch. Scheiner, Galileo developed several arguments on behalf of the hypothesis that sunspots are contiguous to the surface of the Sun, and presented them in his Istoria e dimostrazioni ...

Deciphering Solar Magnetic Activity: Spotting Solar Cycle 25
Frontiers in Astronomy and Space Sciences, 2017 We present observational signatures of solar cycle 25 onset. Those signatures are visibly following a migratory path from high to low latitudes. They had starting points that are asymmetrically offset in each hemisphere at times that are 21–22 years ...
