A Machine Learning Prediction Model to Identify Individuals at Risk of 5-Year Incident Stroke Based on Retinal Imaging

Sensors
Stroke is a leading cause of death and disability in developed countries. We validated an AI-based prediction model for incident stroke using sensors such as fundus cameras and ophthalmoscopes for retinal images, along with socio-demographic data and ...

An Evaluation of Oral Subchronic Toxicity of Maizinol (UP165), a Zea mays Leaf Extract

Journal of Applied Toxicology, Volume 46, Issue 3, Page 932-949, March 2026.
ABSTRACT Maize (Zea mays) has been consumed by humans for millennia and represents the third most abundant crop grown globally. Maize and maize‐derived products have a long history of safe consumption from bread and other cereal products in human diets worldwide. Aside from key dietary components like carbohydrates and proteins, the corn plant contains

Noninvasive 11.7‐T Magnetic Resonance Spectroscopy and Imaging Reveals Retinal Metabolic Alterations Induced by Blue Light Exposure

NMR in Biomedicine, Volume 39, Issue 3, March 2026.
Retinal metabolic changes were analyzed using proton magnetic resonance spectroscopy (1H‐MRS), marking an initial application of this non‐invasive method on living eyes. Key metabolites were identified within the retinal region of adult rats. The observed changes following intense blue light exposure were predominantly attributable to the retina, as it

Population‐Based Cohort Study for Development of National Retinopathy of Prematurity Screening Criteria

Acta Paediatrica, Volume 115, Issue 3, Page 671-678, March 2026.
ABSTRACT Aim Screening criteria for retinopathy of prematurity (ROP) vary among countries. Early detection of ROP and minimising the burden of screening are important. Methods We analysed data from very preterm infants born in Switzerland between 2006 and 2022.

Visual Function Assessment in Geographic Atrophy: A Review

Clinical &Experimental Ophthalmology, Volume 54, Issue 2, Page 260-274, March 2026.
ABSTRACT Geographic atrophy (GA) causes significant vision impairment and reduction in vision‐related quality of life. Fundus autofluorescence (FAF) is the gold standard of structural assessment of GA but is a surrogate marker for vision loss, which can be assessed by tests of visual function and functional vision.
