| Description: |
Objective: We aimed to develop and standardise a practical systematic screening tool for visual perception impairments after a stroke to replace current subjective methods.Study design: A mixed methods study including test development, a cross-sectional study, and a case series.Methods: Development of the Oxford Visual Perception Screen (OxVPS) follows a published Delphi, a survey and performance data on visual perception tasks. Stakeholder feedback from patients and health professionals improved iterative prototypes. Subsequently, we collected normative data from community dwelling older volunteers without a neurological history. Our case series included patients with ocular conditions or a stroke. For each task of OxVPS, we determined 5th centile cut-off scores. We further explored effects of age, visual acuity, and gender on visual perception through Generalised Linear Models. Results: OxVPS is a 15-minute paper-and-pen assessment comprising 10 tasks including picture naming, star counting, and reading. Normative data of 107 participants demonstrated persistent high performance with most cut-offs near ceiling. Apart from the Figure Copy (p |
