NEURODEGENERATION IN MULTIPLE SCLEROSIS: COMPARISON BETWEEN CLINICAL, NEUROPSYCHOLOGICAL, MRI,AND OPTICAL COHERENCE TOMOGRAPHY PARAMETERS

BACKGROUND AND OBJECTIVE Optical Coherence Tomography (OCT) enables rapid, non-invasive in vivo measurement of retinal nerve fiber layer (RNFL) thickness, reflecting axonal density within the optic nerve. There is still lack of concordance about the use of OCT in clinical routine as a surrogate measure of brain atrophy. Objective: To investigate the role of OCT as possible predictor of disability, cognitive impairment and neurodegeneration in Multiple Sclerosis (MS). MATERIAL AND METHODS We recruited patients affected by MS according to validated criteria at the Neurological Department of the University of Palermo. Patients performed Stratus OCT- 3 Zeiss to assess RNFL and GCS measurements.…
