Researchers at the University of Liverpool are running a new study to test the effectiveness of eye “retraining” treatments in people who experience vision loss after a stroke.
Funded by the nonprofit eye research organization Fight for Sight and the Stroke Association, the study hopes to establish a new standard for care for stroke survivors and save NHS money.
Hemianopia – the loss of vision or blindness in half of the field of vision on the right or left side – occurs suddenly in 30% of stroke survivors and can have a devastating effect on their quality of life. There is currently no cure or treatment available to help people with hemianopia make up for their vision loss. This is variable and not standardized in the NHS. This is due to uncertainty about what works best and when is the best time to get treatment, leading to unfair differences in how people are cared for.
Visual scan training encourages stroke survivors to scan into the “blind” side of their field of vision. This can improve a stroke survivor’s adaptation to vision loss. They are repeatedly trained to practice targeting on both the seeing and the blind side of their visual field. This study, conducted by researchers from Liverpool University, was developed with the help of five stroke survivors and is based on paper visual scan training as it is inexpensive, available to all stroke survivors, and allows them to practice training at home.
The study compared a group of 71 stroke survivors who received eye scan training with a group of stroke survivors who did not. You will be followed for six months to see if treatment can improve visual performance and improve independence in everyday activities. All information is gathered during routine eye clinic visits.
Professor Fiona Rowe from the University of Liverpool is leading the study. She said, “This study builds on an early promising pilot study and addresses an area of treatment for which there is limited evidence and no standard care in the NHS. Visual scan training can benefit stroke survivors by adapting them to hemianopia and hemianopia This can be done anytime, anywhere. There is also the potential for cost savings in the NHS and social care sectors by maximizing the use of their remaining eyesight by stroke survivors, thereby reducing the impact on the activities of daily living. A top priority, the two national surveys among large numbers of patients and caregivers. “
The research study is scheduled to begin on December 1, 2020.
