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

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 ...

Choroidal manifestations of non-ocular sarcoidosis: an enhanced depth imaging OCT study

BMC Ophthalmology
Background Although choroidal thickening was reported as a sign of active inflammation in ocular sarcoidosis, there has been no research on the choroidal changes in non-ocular sarcoidosis (defined as systemic sarcoidosis without overt clinical signs of ...

Fundus Refraction Offset as an Individualized Myopia Biomarker [PDF]

Importance As on-axis metrics, spherical equivalent refraction (SER) and axial length (AL) are limited in capturing individual-level differences in posterior segment anatomy.Objective To propose a fundus-level metric—fundus refraction offset (FRO)—and ...
