简要总结
This pilot study aims to understand how eye movements change in people with vision loss from stroke after completing one of two types of training. The study will look at how eye movements and reading performance change after training. Researchers will compare the results of two groups: one group will complete five clinical training sessions using an eye-tracking machine for 30 minutes each, while the other group will do at-home reading exercises for 20 minutes a day, 5 days a week, for 6 weeks. The goal is to see if there is a difference in performance between the two types of training.

研究组 & 干预措施
Biofeedback Fixation Arm
Biofeedback training is a mind-body therapy that helps people learn to control their involuntary bodily functions, such as eye movements. The goal is to improve eye movement control to improve gaze stability.
干预措施: Biofeedback Fixation Training (Behavioral)
Saccadic Reading Arm
Saccadic reading training helps people to learn to control their involuntary eye movements. The goal is to improve eye movement control to improve saccadic and fixational behaviors during reading activities.
干预措施: Saccadic Reading Training (Behavioral)
结局指标
主要结局
Oculomotor Metrics
时间窗: Pre-training and at 6-weeks.
Participants will be asked to read aloud a series of sentences presented on a display. Eye movements will be recorded in real-time using an Eye-Link 1000 infrared eye-tracking camera, as the patient is reading what is on the display. The primary outcome measure will be the first saccade landing location.
次要结局
- Pepper Visual Skills Reading Test (VSRST)(Pre-training and at 6-weeks.)
