For patients with multiple sclerosis (MS), cognitive impairment (CI) may be a prominent symptom of the disease, even in the early stages.
The retinal layer thickness (RLT) measured by optical coherence tomography (OCT) is considered to be a non-invasive, cost-effective and effective marker of multiple sclerosis (MS) neurodegeneration.
The study data comes from a baseline examination of an intervention study.
The figure above shows the exclusion, withdrawal, and final sample situation.
In this cross-sectional study, patients with at least signs of mild cognitive impairment were examined by OCT, the International MS Cognitive Assessment, and the Attention and Executive Function Test (Trail Making Test [TMT] A and B).
A total of 64 patients entered the study.

In MS patients, at the lower stage of the disease, RLT is particularly related to cognitive flexibility, promoting OCT as a potential marker and advocating further extensive neuropsychological examinations.
In summary, RLT and BICAMS seem to be complementary methods in patients with mild to moderate clinical deficits, because SDMT and BVMT-R have no correlation with RLT when correcting for multiple tests.
Diagnosing OCT may provide opportunities to identify MS patients at risk of CI in a cost-effective and feasible way as early as possible.
