Visual Assessment and its Relationship with Cognitive Performance in Multiple Sclerosis: Optical Coherence Tomography and Low-Contrast Letter Acuity Study (2725)

Objective: To determine associations between visual acuity and optical coherence tomography (OCT) measures with cognitive performance of MS patients and healthy controls (HCs). Background: The relationship between visual impairment and cognitive performance in multiple sclerosis (MS) remains poorly understood. Design/Methods: 141 MS patients (with and without MS optic neuritis; MSON) and 50 HCs underwent neuropsychological, visual, and OCT testing. California Verbal Learning Test (CVLT-II), Brief Visuospatial Memory Test (BVMT-R) and Symbol Digit Modalities Test (SDMT) were used. Visual ability was assessed with 100%, 2.5%, and 1.25% low-contrast letter acuity (LCLA) charts. OCT-derived peripapillary retinal nerve fiber layer (pRNFL), macular volume (MV) and macular ganglion cell inner plexiform (mGCIP) were computed. Results: 100% and 2.5% LCLA associated with SDMT in MS and HCs (r=0.377 and r=0.309, p Conclusions: Poorer visual acuity (LCLA) may confound cognitive testing in MS patients with visual but not auditory stimuli. mGCIP and pRNFL associates with cognitive performance in HCs and MS, respectively.
