Patients underwent clinical evaluation including a tailored questionnaire, brain, vascular, and ophthalmologic investigations, and 3\u2010month follow\u2010up. TVDs were classified according to vascular or nonvascular origin by three independent experts based on all clinical, cerebrovascular, and ophthalmologic investigations, but blind to the questionnaire results. A clinical score was derived based on clinical variables independently associated with a vascular origin, and was externally validated in an independent cohort.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>An ischemic origin of TVD was found in 45% (67\/149) of patients in the derivation cohort. Age and six questions were independently associated with an ischemic origin. A nine\u2010point score (\u226570\u00a0years old\u00a0=\u00a02; monocular visual loss\u00a0=\u00a02; black or white vision\u00a0=\u00a01; single episode\u00a0=\u00a01; lack of headache\u00a0=\u00a02; diffuse, constricted, altitudinal, or lateralized visual loss pattern on drawings\u00a0=\u00a01) showed good discriminative power in identifying ischemic origin (<jats:italic>c<\/jats:italic>\u2010statistic = 0.82) and was replicated in the validation cohort (<jats:italic>n<\/jats:italic>\u00a0=\u00a0130, 25% of ischemic origin, <jats:italic>c<\/jats:italic>\u2010statistic = 0.75). With a score \u2265 4, sensitivity was 85% (95% confidence interval = 68\u221295) and specificity was 52% (95% confidence interval = 41\u221262).
