Background Transient monocular blindness (TMB) is associated with a transient ischemic attack (TIA). The purpose of this study was to investigate the features of TMB in the Japanese population using data from a multicenter retrospective study of TIA. Methods The subjects were consecutive TIA patients admitted to 13 stroke centers within 7 days after symptom onset. We compared clinical characteristics of patients with TMB and those without TMB who had other symptoms of cerebral TIA. Results A total of 464 patients were registered between January 2008 and December 2009, and 444 patients (283 men, mean age: 68.5 years) were included in the analysis. Thirteen patients (2.9%) presented with TMB. Patients with TMB were less likely to arrive at the specialized stroke center quickly than those without TMB (P =.013). Stenotic lesions in the extracranial internal carotid artery were more common in patients with TMB (33.3% versus 9.1%, P =.022). Conclusions TMB was not common in our TIA inpatients. This study suggests that patients with TMB should immediately undergo a diagnostic workup, including brain and vessel imaging, and cardiac evaluation, as is performed in patients with other cerebral TIA symptoms. A larger, prospective cohort is needed to confirm the risks and outcomes of patients with TMB in the Japanese population.
