Study on the Effectiveness and Safety of VRT in Patients With Visual Field Defects
58 participantsStarted 2025-04-15
Plain-language summary
The goal of this clinical trial is to learn if visual restoration therapy (VRT) (a type of treatment that aims to improve vision) works to the visual rehabilitation of patients with visual field defects. It will also learn about the safety of VRT. The main questions it aims to answer are:
* Can visual reconstruction therapy help expand the visual field in patients with visual field defects?
* What medical problems do patients with visual field defects experience during the procedure of VRT? Researchers will look at how patients with visual field defects who use a visual aid in combination with VRT and those who use a visual aid only, compare the visual field expansion at three months to see how well visual reconstruction therapy works.
Participants will:
* will undergo a specialized visual function assessment and be provided with a pair of appropriate vision aids.
* Visit the clinic at one month and three months after enrolment for review of visual function and completion of a Chinese-version Low Vision Quality of Life (CLVQOL) questionnaire.
* Participants receiving VRT will additionally undergo 30 minutes of VRT three times per week for 3 months.
* Keep a diary for their symptoms and severity and frequency of occurrence during treatment.

Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
visual field mean deviation (MD) value
Timeframe: A total of 3 examinations were performed during the trial: before treatment, after 1 month of treatment, and after 3 months of treatment.
