The study aimed to evaluate how glaucoma affects the optical attenuation coefficient of the retinal nerve fiber layer (RNFL) using Spectral Domain Optical Coherence Tomography (SD-OCT) images.
Researchers analyzed OCT images from 10 healthy eyes and 30 glaucomatous eyes at various severity levels, measuring RNFL reflectivity and its relationship to visual function.
Results showed that the RNFL's attenuation coefficient significantly decreased with increased glaucoma severity, particularly in specific locations around the optic nerve head, indicating its potential as a new method for assessing glaucoma.
