Introduction: Transient vision loss (TVL) is a common clinical problem, with a myriad of potential causes that are both sinister and benign. In this review, authors focus on both anatomical and pathobiological factors that can account for monocular and binocular symptoms of TVL, including vascular and non-vascular etiologies that are likely to be encountered in a neuro-ophthalmology practice. Areas covered: Causes of TVL (monocular and binocular), including anterior segment abnormalities, retinal ischemic disorders, optic disc drusen, optic neuritis, orbital lesions, and retrochiasmal visual pathway abnormalities are reviewed. Salient historical features, and examination findings for causes of TVL, are presented, with reference to the published literature on this topic. Expert commentary: The list of potential causes of TVL continues to expand, as does our understanding of pathogenic mechanisms that can temporarily impair visual function. The investigations for TVL vary according to etiology. For this reason, a comprehensive history and thorough examination are essential to avoiding the perils of misdiagnosis. The goal of this review is to provide a framework to guide the diagnostic approach to neuro-ophthalmic causes of TVL, which in turn, will ultimately tailor management strategies for patients with these conditions.
