![]() ![]() Hemianopic participants and healthy adults with simulated hemianopia differed significantly from controls in various fixation and saccade parameters as indicated by increased number and duration of fixations, number and duration of saccades and scan path length with shorter mean saccadic amplitude. ![]() Twenty-nine studies detailed eye, head and body movement parameters in true hemianopia. Seven studies identified the biomechanical alterations to simulated hemianopia compared to normal performance. Thirty-six articles (1123 participants) were included in the overall review (Kappa 0.863) and categorised into simulated or true visual field loss (typically hemianopia). All included articles were assessed for risk of bias using checklists appropriate to the study design. Data were extracted by one author and verified by a second. Articles were selected by two authors independently. Search terms included a range of MESH terms as well as alternative terms relating to stroke, visual field loss, hemianopia, visual functions and scanning behaviour. Studies including adult and paediatric participants that investigated eye, head, or body movements in post-stroke visual field loss during visual exploration tasks were included. MethodsĪ systematic review was conducted inclusive of randomised controlled trials, cohort studies, before-after studies and case-controlled studies. This review aimed to gather the available evidence on the biomechanical changes to visual field loss following stroke. Homonymous visual field defects represent the most frequent type of visual field loss after stroke, affecting nearly 30% of individuals with unilateral post-chiasmal brain damage. ![]()
