Detailed history-taking followed by a complete ocular and neurological examination is therefore a crucial part of any consultation. OBJECTIVE: It is important to determine whether a patient with transient vision loss can be reassured or requires urgent referral for further investigation. This review examines monocular and binocular transient vision loss and provides a structured approach to the examination of a patient with transient vision loss. The aim of this article is to provide clinicians with confidence when encountering these patients. DISCUSSION: Transient vision loss can imply serious underlying pathology; therefore, accurate history-taking and astute observation are paramount. This review discusses the differential diagnosis of monocular and binocular transient vision loss and the relevant localising features of each.application/pdfen-AU© The Royal Australian College of General Practitioners 2021Blackout: Understanding transient vision loss202110.31128/AJGP-03-20-52712021-12-02
