Summary
A new screening tool, the Oxford Visual Perception Screen (OxVPS), has been developed to assess visual perception impairments after stroke. This 15-minute paper-and-pen assessment provides standardized screening, potentially improving clinical practice for stroke patients.
Area of Science:
- Neuroscience
- Ophthalmology
- Psychology
Background:
- Visual perception impairments are common after stroke, often assessed using subjective methods.
- Standardized, objective screening tools are needed to improve diagnostic accuracy and clinical management.
Purpose of the Study:
- To develop and standardize a practical, systematic screening tool for visual perception impairments post-stroke.
- To replace current subjective assessment methods with an objective measure.
Main Methods:
- A mixed-methods study involving a cross-sectional study and a case series.
- Development of the Oxford Visual Perception Screen (OxVPS), a 15-minute paper-and-pen assessment with 10 tasks.
- Determination of 5th centile cut-off scores using normative data from 107 participants and analysis of factors influencing performance.
Main Results:
- The Oxford Visual Perception Screen (OxVPS) is a 15-minute, 10-task assessment.
- Normative data showed high performance, with most cut-off scores near ceiling.
- Age affected Face Recognition and Reading tasks; visual acuity affected Figure Copy and Global Shape Perception.
Conclusions:
- The Oxford Visual Perception Screen (OxVPS) is a standardized tool for screening visual perception impairments.
- It provides normative data and illustrative cases for clinical interpretation.
- The OxVPS has the potential to significantly change the screening process for visual perception deficits in clinical settings.
