This project is lead by Dr Kathleen Vancleef and funded by her Stroke Association postdoctoral fellowship, as well as additional funding from a Christ Church College grant to Dr Vancleef.

Many patients suffer from reduced vision after stroke. This prevents them from driving and can make it difficult for them to safely cross the road or participate in social situations. Although it is straightforward for a health professional to diagnose a stroke patient’s reduced visual acuity by reading a letter chart, it’s much more challenging for them to detect visual perception deficits such as recognising objects or faces, or a patient seeing motion.

Existing vision tests do not tell us how a patient’s life will be influenced by their vision problems. This project aims to understand how the results of vision tests relate to a stroke survivor’s functioning in their daily lives.The results of the research could provide patients with more meaningful information about their condition. Information which could help them target certain visual functions through exercises, or help them make the necessary adjustments in their lives to compensate for their impairment.


The Oxford Cognitive Screen (OCS) was developed as an inclusive, domain-specific screen for first line cognitive screening post stroke.

The OCS (Oxford Cognitive Screen) can be delivered at the bedside in acute stroke, is easy to administer and score and is inclusive for patients with aphasia and neglect. It returns a visual snapshot of a patient’s cognitive profile which summarises performance across 5 cognitive domains.  [image wheel ]

In order to help us keep track of the spread of use of this cognitive screen, the test materials are being licensed for use through Oxford University Innovation.  The test materials’ licensing agreement is free of charge for publicly funded clinical and research use, though charges will apply for use by commercial entities.

The Oxford Cognitive Screen should always be made available free of charge to patients.

Please find more specifics on how to administer OCS, including a demonstration video and information on different language versions of OCS on www.ocs-test.org
