OCS vs VISA Screen

OCS-Plus provides health professionals with a brief cognitive assessment focussed on memory and executive attention. OCS-Plus was developed by the Translational Neuropsychology Research Group at the University of Oxford. The tool has been standardised, normed and validated (Demeyere et al 2021). The tool is currently undergoing further research for validity of use in specific clinical groups. The tool is not for self-assessment. Instead, a health professional assessor administers the screen to respondents to investigate domain-general cognitive impairments, with a specific focus on memory and executive attention. The tool contains multiple easy to administer tests and instructions are provided for each test. Normative data is provided for three age groups : under 60, between 60 and 70, and older than 70 and respondent performance is automatically compared to established normative cut offs. In order to activate the app for use, registration is required. There is no cost for the standard app version where data is not uploaded. Where data upload is required, an administration fee, as well as a collaboration agreement and datasharing agreement is required to be put in place.

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
