Retinal thickness holds clues to MS progression
Two studies published by neurologists from the Johns Hopkins University, US, demonstrated that thickness or swelling of the inner nuclear layer of the retina was associated with more extensive brain atrophy in patients with MS.
They used optical coherence tomography to visualise retinal thickness and matched it with inflammation in MRI scans.
