Different alteration patterns of sub‐macular choroidal thicknesses in aquaporin‐4 immunoglobulin G antibodies sero‐positive neuromyelitis optica spectrum diseases and isolated optic neuritis

The ocular choroid is a sensitive biomarker of vascular perfusion in optic neuritis (ON) patients due to its vascular structures. The purpose of this study was to evaluate alterations in sub‐macular choroidal thicknesses (sub‐MCT) in aquaporin‐4 immunoglobulin G antibodies (AQP4‐IgG) sero‐positive neuromyelitis optica spectrum disease (AQP4‐IgG+/NMOSD) and isolated ON (ION) patients using optical coherence tomography (OCT).
