New Eye-Scan Breakthrough Could Make Glaucoma Detection More Reliable

This study examines the validity of retinal nerve fiber layer (RNFL) reflectance metrics for glaucoma assessment using spectral-domain optical coherence tomography (OCT). To assess the impact of optical attenuation, we compared several normalization strategies, such as pigment epithelium complex (PPEC), Post-NFL-Mean, and a novel Post-NFL-Bright method that selects the top 50% of high-intensity pixels.
