Importance of Clinical Trials
Effective treatments for visual field defects (VFDs) in stroke patients need to be tested through clinical trials.
Objective of the Study
This study aimed to assess the safety and effectiveness of a personalized digital therapy that uses visual perceptual learning to treat VFDs after a stroke.
Study Overview
The trial took place from October 2022 to November 2023 in 12 hospitals in South Korea. It involved stroke patients aged 19 and older who had persistent VFDs for more than three months.
Intervention Details
The training group used a mobile virtual reality headset for personalized visual tasks five days a week for 12 weeks. The control group did not receive any treatment.
Main Outcomes
The primary goal was to measure improvements in visual sensitivity, assessed through visual field tests at the start and after 12 weeks.
Results
Out of 93 patients, 82 completed the study. The training group showed significant improvements in visual sensitivity compared to the control group:
- Whole field improvement: 72 degrees squared (P = .003)
- Defective hemifield improvement: 72 degrees squared (P = .002)
Secondary measures also showed improvements in the training group, while the control group did not see any significant changes.
Conclusions
This trial demonstrated that digital therapy based on visual perceptual learning can significantly improve visual fields in chronic poststroke patients.
Opportunities for Clinics and Patients
Based on the trial data, clinics can:
- Set measurable outcomes for patient progress.
- Define clear goals for using personalized digital therapy.
- Select AI tools that meet specific clinical needs.
- Implement the therapy step by step, starting with pilot projects.
