简要总结
In patients with hemianopsia following stroke or brain injury, we will determine if stimulating the visual field with images from a PowerPoint slide set can increase the visual field.
详细描述
Purpose: To determine if a computer screen visual stimulation can improve peripheral field loss in patients with vision pathway brain injury.
Hypothesis: Visual stimulation helps patients with visual pathway brain injury recover peripheral vision.
Justification: i) Axonal sprouting or re-rerouting can occur after brain injury ii) In Canada stroke prevalence comprises almost 900,000 patients. (Canada.ca, Health 2022). It is estimated that half of stroke survivors have a visual field deficit. (Rowe et al, PLoS One. 2019).
There is clinical equipoise regarding the results of vision therapy with visual stimulation. Romano JG, et al. Journal of the Neurological Sciences. 2008 Oct 15;273(1-2):70-4. versus Horton JC. Disappointing results from Nova Vision's visual restoration therapy. British Journal of Ophthalmology. 2005
Objectives: To determine the effect size of visual recovery, if any with computer screen visual stimulation
