What the trial is, and whether it could suit you
Multiple sclerosis (MS) affects approximately 2.3 million patients worldwide, with a global median prevalence of 33 per 100,000. MS is diagnosed at an average of 30 years and affects twice as many women as men. MS is traditionally diagnosed by the presentation of lesions of the central nervous system, disseminated in time and in space, proven by clinical examination and magnetic resonance imaging. Several anatomical parameters in the eye, both vascular and neural, have been found to be altered in MS patients.
Because of its unique optical properties, the eye offers the possibility of the non-invasive assessment of both structural and functional alterations in neuronal tissue. As the neuro-retina is part of the brain, it does not come as a surprise that neuro-degenerative changes in the brain are accompanied by structural and possibly also functional changes in the neuro-retina and the o

📋 Eligibility rules (as published)
Inclusion criteria for healthy subjects:
* Men and women aged over 18 years
* Non-smokers
* Normal findings in the medical history unless the investigator considers an abnormality to be clinically irrelevant
* Normal ophthalmic findings, ametropy \< 6 Dpt.
Inclusion criteria for patients with MS:
* Men and women aged over 18 years
* Diagnosis of relapsing-remitting multiple sclerosis (RRMS) according to clinical evaluation and McDonald criteria (revision 2010)
* History of AON in one eye at least one year ago
* Non-smokers
* Normal ophthalmic findings, ametropy \< 6 Dpt.
* Adequate visual acuity to allow participation in the ocular blood flow measurements
* A potential participant has to be on stable doses of all medications he/she is taking because of consisting illnesses according to medical history (except MS therapy itself which will be recorded separately) for at least 30 days prior inclusion, if considered relevant by the investigator.
