An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

Experimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Reproducibility in the identification of retinal positions on serial fundus photographs: Theory and limitations

Acta Ophthalmologica, Volume 104, Issue 2, Page 201-211, March 2026.
Abstract Background Imaging of the retina is accompanied by distortions so that positions in fundus photographs cannot be linearly translated to positions in the retinal fundus. The purpose of this study was to describe an algorithm and evaluate its reproducibility in identifying points on the retina from their representation on serial fundus ...

Beyond Treatment: The Strategy of Nonintervention in Choroidal Hemangioma

Clinical Case Reports
The circumscribed choroidal hemangioma (CCH) is a benign congenital eye tumor whose etiology is not clear. A 41‐year‐old female patient came with a 2‐year history of slowly progressive deteriorating vision in her right eye.

Personalized Models of Biological Barriers and Their Diseases: Recent Progress with Organs‐On‐Chips

Advanced Biology, Volume 10, Issue 2, February 2026.
Buck and Bugter et al. explore the architectural diversity and physiological functions of human barrier systems and reveal how organ‐on‐chip platforms, particularly those integrating patient‐derived cells, are advancing barrier disease modeling. They highlight how emerging biological and technological advances can be used to bridge the gap between ...
