简要总结
This study evaluates the efficacy of visual perceptual learning for the treatment of visual field defect caused by brain damage. Half of participants will receive visual perceptual training using the Nunap Vision, while the other half will receive sham training using the Nunap Vision-C.

结局指标
主要结局
Area of Humphrey visual field where sensitivity increased by equal or more than 6 dB relative to baseline
时间窗: 12 weeks
Improved regions have luminance sensitivity that increased by equal or more than 6 dB relative to baseline. The improved area ranges between 0 and 972 degree\^2, of which larger area indicates better outcome.
次要结局
- Changes in Humphrey visual field mean deviation relative to baseline(12 weeks)
- Changes in scores of NEI-VFQ-25(the National Eye Institute Visual Function Questionnaire 25) relative to baseline(12 weeks)
