Abstract

Background: A transient visual symptom (TVS) is a clinical manifestation of transient ischemic attack (TIA). The aim of this study was to investigate differences in clinical characteristics among subtypes of TVS using multicenter TIA registry data. Materials and Methods: Patients with TIA visiting within 7 days of onset were prospectively enrolled from 57 hospitals between June 2011 and December 2013. Clinical characteristics were compared between patients with 3 major subtypes of TVS (transient monocular blindness [TMB], homonymous lateral hemianopia [HLH], and diplopia). Results: Of 1365 patients, 106 (7.8%) had TVS, including 40 TMB (38%), 34 HLH (32%), 17 diplopia (16%), and 15 others/unknown (14%). Ninety-one patients with 1 of the 3 major subtypes of TVS were included. Symptoms persisted on arrival in 12 (13%) patients. Isolated TVS was significantly more common in TMB than in HLH and diplopia (88%, 62%, and 0%, respectively; P <.001). Duration of symptoms was shorter in patients with TMB than those with HLH (P =.004). The ABCD2 score was significantly lower in patients with TMB compared with those with HLH and diplopia (median 2 [interquartile range 2-3] versus 3 [2-4] and 4 [2-5], respectively; P =.005). Symptomatic extracranial internal carotid artery stenosis or occlusion was seen in 14 (16%) patients, and was more frequent in TMB than in HLH and diplopia (28%, 9%, and 0%, respectively; P =.015). Conclusions: TVS was an uncommon symptom in our TIA multicenter cohort. Some differences in clinical characteristics were found among subtypes of TVS.
