Brief Summary:
This prospective interventional study evaluates the anatomical and functional outcomes of autologous Tenon's capsule grafting in patients with refractory full-thickness macular holes. Eligible patients include those with chronic large macular holes (\>400 µm) or persistent holes following prior pars plana vitrectomy with internal limiting membrane peeling and gas tamponade. Anatomical closure will be assessed using spectral-domain optical coherence tomography, and functional outcomes will be evaluated by best-corrected visual acuity over a 3-month follow-up period.
Detailed Description:
Refractory full-thickness macular holes represent a significant surgical challenge, with reduced closure rates following conventional techniques, particularly in large or chronic defects. Autologous tissue grafting has emerged as an alternative strategy to provide a biological scaffold for retinal tissue bridging and gliosis. Tenon's capsule is a readily accessible autologous fibrovascular tissue that can be harvested intraoperatively with minimal morbidity.
This prospective single-arm clinical study aims to assess the anatomical closure rate and visual outcomes following autologous Tenon's capsule graft placement in refractory macular holes. All patients will undergo standard pars plana vitrectomy, placement of a trimmed Tenon's graft into the macular hole, and silicone oil tamponade. Outcomes will be evaluated using standardized visual acuity testing and spectral-domain OCT imaging at predefined postoperative intervals.
