Community-based Multi-center Randomized Control Trial of Peripheral Prism Glasses for Hemianopia
In Brief
A clinical study evaluating High power (57 prism diopter) peripheral prism glasses and Low power sham peripheral prism glasses for Homonymous Hemianopia. Completed, enrolled 73 participants across 13 sites in 2 countries.
Detailed Summary
The purpose of this study is to evaluate the functional utility for general mobility (walking) of new high power permanent peripheral prism glasses, which provide visual field expansion device for patients with homonymous hemianopia (the complete loss of half the field of vision on the same side in both eyes). The efficacy of real peripheral prism glasses will be assessed relative to sham peripheral prism glasses.
Study Details
Timeline
Interventions
All patients will wear two pairs of prism glasses in a crossover design: the high power peripheral prism glasses and sham peripheral prism glasses. Each pair of prism glasses will be worn for four weeks
Low power (5 prism dioptre) prism glasses that provide only about 2 degrees of visual field expansion.
