Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.
Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Patients with a history of acute optic neuritis (ON) and/or who experienced an episode of ON \<6 months prior to the study, to avoid potential interference of papilledema with accurate peripapillary RNFL thickness measurements.
Other illness
- Patients with other retinal and optic nerve diseases, advanced cataracts according to the international Lens Opacities Classification System III (LOCS III) (opacities greater than C2N2)
- Patients with other ophthalmological diseases that could affect central visual acuity
- Subjects with other demyelinating disorders (neuromyelitis optica or acute disseminated encephalomyelitis).
Other
- Subjects with high refractive error (+ - 6 diopters).
Who the study is looking for
- Diagnosis of Multiple Sclerosis
- Best distant corrected visual acuity equal or greater than 0.7 (decimal scale). Glasses or soft contact lenses users.
- Best close corrected visual acuity equal to or greater than 20/30 (Snellen scale).Glasses or soft contact lenses users.
Age in the registry: 18 years to 80 years · Sex: All · Accepts healthy volunteers
