Simulated Walking With Multiplexing Prism for Field Expansion in Monocular Vision
Stopped: Investigators left the research institute.
United States0Started 2024-08-04
Plain-language summary
The investigators are developing an assistive device, known as multiplexing prism that expands the field of view for individuals with acquired monocular vision (loss of an eye). The investigators will test the efficacy of the prism in improving the detection of colliding pedestrians during a simulated walking task.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* No medical health issues such as seizures, motor movements problem
* Loss of vision in one eye (less than 20/200) for \>1 year
* Visual acuity of the seeing eye: Better than 20/32 visual acuity with correction
* No visual field defect in the seeing eye (nasal field of at least \>45degree)
Exclusion Criteria:
* Patients with any physical or mental disabilities, including cognitive dysfunction, balance problems, or other deficits that could impair their ability to respond to the stimuli presented in this study will be excluded
* Any person with a history (such as pacemaker use or photosensitive epilepsy)
* Any person with motor movements problem (e.g., unable to use extremities)
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.
