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.

Peripapillary Choroidal Vascularity Index and Microstructure of Parapapillary Atrophy

Investigative Opthalmology & Visual Science, 2019
To investigate the association between the microstructure of β-zone parapapillary atrophy (βPPA) and choroidal vascularity index (CVI) determined by spectral-domain optical coherence tomography (SD-OCT) in glaucomatous eyes.A total of 160 eyes of 160 primary open-angle glaucoma patients with βPPA were included. Total choroidal area (TCA), luminal area (

Quantification of Vascular Burden on Cranial Vessel Wall Magnetic Resonance Imaging and Ophthalmic Complications in Giant Cell Arteritis

ACR Open Rheumatology, Volume 8, Issue 5, May 2026.
Objective There is a need for measures of disease severity for giant cell arteritis (GCA), which may enable identification of high‐risk subgroups (eg, ophthalmic complications) and individualized approaches to therapy. We derived a continuous score using data from cranial vessel wall magnetic resonance imaging (VW‐MRI) to quantify vascular burden in ...

Optimal Surgical Timing and Outcome Prediction in Hemorrhagic Moyamoya Disease: A Retrospective Cohort Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 5, May 2026.
This cohort study developed and validated the first prognostic nomogram for hemorrhagic MMD, incorporating five independent predictors including a defined optimal surgical window of 3 to 6 months. The model demonstrated good discrimination and aids in risk stratification for clinical monitoring.

A Cationic Block Co‐Polymer for Gene Delivery in the Posterior Segment of the Eye

Journal of Biomedical Materials Research Part A, Volume 114, Issue 5, May 2026.
ABSTRACT Diseases of the back of the eye such as neovascular age‐related macular degeneration (nAMD) are vision threatening and treatment is burdensome for patients, often requiring ocular injections every other month. Injection risks and logistics lower patient compliance; however, even patients receiving optimal treatment can deteriorate.

Choroidal vascular hyperpermeability patterns in central serous chorioretinopathy correlate with microperimetry: CERTAIN study report 4

Acta Ophthalmologica, Volume 104, Issue 3, Page 288-295, May 2026.
Abstract Purpose This report evaluates the association of three distinct leakage patterns of choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA), previously correlated with disease chronicity, with retinal sensitivity measured by microperimetry in central serous chorioretinopathy (CSC): unifocal indistinct signs of ...

Consensus on age‐related macular degeneration course curricula for general ophthalmologists and non‐ophthalmologist clinical staff: A Delphi study

Acta Ophthalmologica, Volume 104, Issue 3, Page e269-e276, May 2026.
Abstract Purpose To define the curriculum content for two interactive learning courses on age‐related macular degeneration (AMD): (1) an advanced course tailored for general ophthalmologists and (2) a basic course for non‐ophthalmologist healthcare staff.
