NCT03703180

Brief Summary

Victor2 is an observational cohort study over two years and is designed to investigate longitudinal changes of visual impairment in multiple sclerosis (MS). The investigators aim to recruit patients in the relapsing-remitting phase of the disease (n=50) as well as progressive MS patients (n=50). Both cohorts will be compared with age and gender matched healthy controls (HC). All participants undergo yearly clinical assessments including standard charts for visual acuity (Sloan, Snellen), a new computer adaptive test measuring the complete contrast sensitive function (CSF), optical coherence tomography and a vision related quality of life questionnaire (NEI-VFQ). The study aims to validate and extend previous finding from a cross-sectional study which found a better association between CSF and NEI-VFQ than for standard charts. Moreover, the study is designed to proof also a better association with anterior visual system integrity as assessed with OCT.

Outcome Measures

Primary Outcomes (1)

  • Correlation between ganglion cell / inner plexiform layer (GCIPL) thickness loss and area under the log CSF curve change over two years

    GCIPL thickness represents anterior visual system integrity on neuronal level and its change over two years will be correlated with the change of the CSF

    2 years

Secondary Outcomes (2)

  • Correlation between retinal nerve fibre layer (RNFL) thickness loss and area under the log CSF curve change over two years

    2 years

  • Longitudinal correlation between visual quality of life and contrast vision

    2 years

Study Arms (2)

MS

representative cohort of relapsing-remitting MS (n=50) and progressive MS patients (n=50) over the typical age range of 18-65. During two years of follow-up the integrity and function of the visual system will be observed annually with optical coherence tomography, high and low contrast visual acuity and a vision related quality of life questionnaire.

Controls

Age and Gender matched healthy controls (n=100) will undergo the same assessments as the MS cohort to build up a representative normative dataset.
