A Case of Recurrent Transient Monocular Blindness in Systemic Lupus Erythematosus patient with Antiphospholipid Antibody Syndrome

Transient monocular blindness (TMB) may occur in patients with systemic lupus erythematosus (SLE). Several mechanisms have been suspected as the causes of such TMBs. A 32-year-old female patient with SLE presented recurrent monocular altitudinal visual field defects lasting for several minutes and occurring less than six times per day. Her anticardiolipin antibody level was persistently positive. All cerebrovascular imagings were normal. We report a case of recurrent TMBs in SLE with antiphospholipid antibody syndrome, which may have been induced by vasospasm.
