Abstract:BACKGROUND: Thinning of the retinal combined ganglion cell and inner plexiform layer (GCIP) as measured by optical coherence tomography (OCT) is a common finding in patients with multiple sclerosis. This study aimed to investigate whether a single retinal OCT analysis allows prediction of future disease activity after a first demyelinating event. METHODS: Observational cohort study including 201 patients with recently diagnosed clinically isolated syndrome or relapsing remitting multiple sclerosis from two German tertiary referral centers. Individuals underwent neurological examination, MRI and OCT at baseline and at yearly follow-up visits. RESULTS: Patients were included at a median disease duration of 2.0 months. During a median follow-up of 59 (interquartile range 43 - 71) months, 82% of patients had ongoing disease activity as demonstrated by failing the no evidence of disease activity (NEDA)-3 criteria and 19% presented with confirmed disability worsening. A GCIP threshold ≤ 77 μm at baseline identified patients with a high risk for NEDA-3 failure (hazard ratio 1.7 [95% CI 1.1 - 2.8], p=0.04) and GCIP measures ≤ 69 μm predicted disability worsening (hazard ratio 2.2 (95% CI, 1.2 - 4.3); p=0.01). Higher rates of annualized GCIP loss increased the risk for disability worsening (hazard ratio 2.5 per 1 μm/year increase of GCIP loss, p=0.03). CONCLUSIONS: Ganglion cell thickness as measured by OCT after the initial manifestation of multiple sclerosis may allow early risk stratification as to future disease activity and progression.
