Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with an idiopathic full-thickness macular hole and symptom duration of less than 6 months.
✕Probably not a fit
Patients with a macular hole diameter greater than 1000 μm or those with a history of high myopia or other specified eye conditions may not benefit from this study.

What this trial studies
This clinical trial investigates the optimal duration of face-down positioning required after surgical repair of full-thickness macular holes. It randomly assigns participants to either 3 days or 7 days of face-down positioning following pars plana vitrectomy. The study aims to assess key outcomes such as macular hole closure rates, visual acuity, quality of life, patient compliance, and complication rates. This feasibility study will provide valuable insights for a future larger clinical trial.
Why it matters
Potential benefit: If successful, this study could help determine the minimum required recovery time for patients, potentially improving comfort and compliance.
How similar studies have gone: While this approach is novel in its specific comparison of positioning durations, similar studies on post-surgical positioning have shown varying success.
