VISA Screen vs OxMET

The Vision Impairment Screening Assessment (VISA) screening tool is intended to aid detection for visual problems outside ophthalmic clinics and practices. It is intended to aid screening and identification of visual problems after which the referral form should be used to refer the individual to formal eye care services for full investigation and diagnosis of the visual issue. VISA contains the following sections: - Patient history - Visual acuity - Ocular alignment and movement - Kinetic visual field test - Visual inattention

OxMET was developed by the Translational Neuropsychology Research Group at the University of Oxford. The OxMET cognitive screen has been standardised, normed and validated (Webb et al 2021, Neuropsychological Rehabilitation). OxMET is suitable for use with adults, and in chronic (greater 6-month post-stoke) and subacute (greater 3 months post-stroke). The tool is not for self-assessment. Instead, OxMET provides health professionals with a brief, ecologically valid, assessment of executive dysfunction using a naturalistic shopping scenario. The test is automatically scored and evaluated against age adjusted norms (three age groups; under 64, between 64 and 72, and over 72). Upon completion, a visual snapshot report is automatically generated and can be stored locally on the device. The information contained in the report is not in itself a clinical diagnosis. The report should be used to inform a clinical diagnosis that takes into account all relevant clinical factors.
