Evaluating head positioning after retinal detachment repair
Official title: Head Positioning Duration After Retinal Detachment Repair With Vitrectomy and Gas
Run by University of Kansas Medical Center · NCT03714503 · Data updated 2026-11-12
This study is testing if lying face down for just one day after retinal detachment surgery works as well as lying face down for seven days for patients with certain types of retinal breaks.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older diagnosed with primary rhegmatogenous retinal detachment with inferior breaks.
✕Probably not a fit
Patients who may not benefit include those with a history of previous retinal detachment repair in the study eye or those with other specific retinal conditions.

What this trial studies
This study investigates whether one day of prone head positioning after surgery for retinal detachment is as effective as seven days of the same positioning. It focuses on patients with inferior retinal breaks who have undergone pars plana vitrectomy using C3F8 gas as a tamponade. The study employs a single-arm phase II design with a Simon's two-stage approach to assess the anatomical success of the retina at three months and one year post-operatively. A total of 20 patients will be recruited, with the first stage determining if the trial should continue based on initial success rates.
Why it matters
Potential benefit: If successful, this study could reduce the duration of required prone positioning after retinal detachment surgery, improving patient comfort and compliance.
How similar studies have gone: While similar studies have explored post-operative positioning, this specific approach is novel and has not been extensively tested.
