Analysis of Novel Positioning Sensor-assisted Postoperative Position Correction and Effective Prone Time Recorded in Patients With Different Prone Times After Macular Hole Surgery
China86 participantsStarted 2022-10-01
Plain-language summary
Idiopathic macular hole (IMH) is a fundus disease without clear etiology, most often seen in healthy women over 50 years of age, and is often associated with ocular manifestations such as loss of central vision and visual distortion. It is often associated with loss of central vision, visual distortion, and other ocular manifestations. It is currently treated by vitrectomy combined with internal limiting membranes (ILM) peeling followed by gas filling. A strict prone position for a certain period of time after surgery has a positive effect on the healing of the macular fissure. The need for a strict prone position after IMH has been demonstrated in previous studies (especially when the IMH diameter is \>400 μm). However, due to the anti-human mechanics of the face-down position, patient comfort, sleep quality and quality of life are greatly compromised. Therefore, this study designed a smart head position monitoring device to assist patients in maintaining the correct position and recording the effective position time. The study was conducted to determine the shortest prone position time based on macular fissure closure, to minimize the adverse effects of postoperative position, and to obtain the maximum recovery of visual acuity and visual field.

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.
