Feasibility of In Vivo Retinal Flavoprotein Autofluorescence Imaging in a Magnetic‐Bead‐Induced Rodent Glaucoma Model

open access: yesJournal of Biophotonics, Volume 19, Issue 6, June 2026.
A scanning laser ophthalmoscope, integrated with a real‐time optical coherence tomography (OCT) alignment monitor, detected flavoprotein fluorescence (FPF) signals associated with mitochondrial dysfunction in a rodent glaucoma model. Under 450‐nm excitation, experimental eyes showed spatially inhomogeneous signals that were absent under 505‐nm ...
