Ten modern techniques for full-thickness macular hole repair compared
Official title: Vitreoretinal Surgery for Full-Thickness Macular Hole: A Comparative Study of Ten Techniques
Run by Kazakh Eye Research Institute · NCT07606404 · Data updated 2026-11-12
We are testing ten different surgical approaches to fix full-thickness macular holes in adults to see which method closes the hole best and gives the best vision.

Is this trial a fit for you?
✓Likely a good fit
Adults with a full-thickness macular hole suitable for pars plana vitrectomy, across a range of hole sizes, including small holes.
✕Probably not a fit
Patients with holes unlikely to close with surgery or with conditions that could obscure functional gains may see limited benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This single-center, randomized study assigns eligible adults with full-thickness macular holes to one of ten PPV-based surgical techniques, with stratification by hole size. Surgeons perform the procedures during pars plana vitrectomy and standardized postoperative care is followed. Key outcomes include anatomical hole closure on OCT and visual acuity, assessed at Day 7, Month 1, and Year 1, along with safety and reoperation rates. The trial also evaluates adjuncts like autologous PRP and human amniotic membrane grafts as part of the interventions.
Why it matters
Potential benefit: If successful, the study could identify a surgical approach that improves the likelihood of hole closure and better vision for patients.
How similar studies have gone: Prior studies suggest favorable results with advanced ILM flap techniques, but this trial explores multiple modern approaches in a randomized, controlled manner.

Show full inclusion / exclusion criteria
Inclusion Criteria: Adults aged ≥18 years. Full-thickness macular hole (FTMH) eligible for pars plana vitrectomy (PPV). Symptom duration ≤12 months. Clear ocular media sufficient for high-quality OCT imaging. No prior pars plana vitrectomy in the study eye. No severe foveal atrophy on OCT. Able and willing to comply with postoperative positioning and follow-up visits. Written informed consent provided. Exclusion Criteria: A. Etiology-Related / Secondary Macular Holes: Traumatic macular hole. High myopia with posterior staphyloma (axial length \>28 mm and/or spherical equivalent ≤-8.0 D). Diabetic tractional retinal detachment (TRD) or significant tractional maculopathy. Retinal vascular occlusion-related macular hole. Uveitis-related macular hole. Advanced age-related macular degeneration (AMD) with foveal atrophy. B. Prior Interventions: Any prior pars plana vitrectomy in the study eye. C. Ocular Conditions That May Affect Outcomes or Safety: Active or recent ocular infection or inflammation (e.g., uveitis, endophthalmitis, keratitis). Uncontrolled glaucoma (intraocular pressure \>28 mmHg despite treatment). Media opacity precluding adequate OCT (e.g., dense cataract or corneal opacity). Geographic atrophy involving the fovea.
