Sight loss following stroke: Impact and rehabilitation
Margaret Martin, Medical Journalist and Independent Researcher
Researchers are calling for more widespread investigation into the merits of neurological vision training (NVT) for patients living with stroke-induced sight loss. A small-scale study into the effects of NVT scanner training published by Thomas Pocklington Trust revealed positive indications of the treatment’s effectiveness based on a limited body of evidence.
About one third of people who have had a stroke experience some form of sight loss.
In the majority of patients sight is lost in half of the visual field in the same side of each eye. This is called homonymous hemianopia.
The impact of this condition on activities of everyday living can be devastating at home and in the community.
How can this research help?
The findings provide limited evidence that NVT scanning training is a promising intervention, which merits further research. The publication suggests areas of further research and ways in which therapies can be best used.
