Post-stroke visual midline shift syndrome

Abstract

The state of research on the topic of visual midline shift syndrome following a cerebrovascular accident is unknown. A scoping review was conducted using the search terms of 'visual midline shift' (or equivalent) and 'cerebrovascular accident' (or equivalent). Articles were selected from eight academic and one grey literature database, and went through two levels of review, as per Arksey and O'Malley, before being deemed acceptable for inclusion. Of the 931 abstracts reviewed, 27 articles met the criteria for inclusion. Data extracted from the selected articles included terminology and definition, symptoms, underlying pathophysiology, duration, assessment method, and management of visual midline shift syndrome following cerebrovascular accident. There is agreement on the existence of a midline shift following a cerebrovascular accident resulting in poor posture and imbalance. Much uncertainty exists in the literature regarding terminology, underlying pathophysiology, assessment method and management of this condition. Further research is required.
