“…The review of the literature revealed that optic neuritis represents the 46.4% (124/267) of cranial neuritis in SS patients [ 7 , 18 , 19 , 24 , 34 , 36 , 43 – 45 , 49 , 54 – 56 , 59 , 63 , 65 – 68 , 70 , 72 – 75 , 77 – 81 , 83 , 85 – 93 , 95 – 97 , 100 , 104 ]; it is often bilateral with contemporary [ 65 , 67 , 68 , 70 , 85 , 89 , 95 , 97 ] or sequential [ 36 , 63 ] occurrence. In a few cases, neuritis was associated with CNS involvement, such as brain vasculitis [ 34 , 77 ], acute transverse myelopathy [ 43 , 67 ], myelitis [ 77 , 80 , 83 , 90 ], aseptic meningitis [ 70 ], or multiple sclerosis-like features [ 80 , 91 ].…”
