Assessment of Outer Retina and Choroid Using Swept Source Optical Coherence Tomography and Angiography in Patients With Multiple Sclerosis.

Our study indicates that patients with MS with no history of optical neuritis have reduced choriocapillaris vessel density and decreased choroidal vascularity index without detectable alteration in outer retina thickness and choroid thickness. The findings complement the outer retinal and choroidal component of MS, providing deeper insight into the pathophysiology of MS.
