Optical Coherence Tomography as a Biomarker for Diagnosis, Progression, and Prognosis of Neurodegenerative Diseases

Figure 1

Optic nerve head (a) and retinal nerve fiber layer analysis (b) as obtained with swept-source optical coherence tomography in a 43-year-old patient with multiple sclerosis who suffered a previous episode of optic neuritis 5 years ago. The pixel map and the clock sector analysis (marked with the white square) of the optic disc shows important retinal nerve fiber layer loss in most sectors of the peripapillary area.
