Autologous Tenon's capsule for post-vitrectomy macular hole closure: A case report
Abstract
Purpose To report the anatomical and visual outcomes of autologous Tenon's capsule patch grafting for closure of a large post-vitrectomy full-thickness macular hole. Observations A 63-year-old female with proliferative diabetic retinopathy presented with decreased vision in the right eye. Optical coherence tomography demonstrated a 1112 μm full-thickness macular hole. Due to prior internal limiting membrane peeling, insufficient tissue remained for conventional techniques, an autologous Tenon's capsule graft was harvested through a limited conjunctival peritomy and positioned on the macular defect. Silicone oil tamponade was used to stabilize the graft. One-month follow-up demonstrated anatomical closure of the macular hole, which remained stable at 6 months. Visual acuity improved from hand motion preoperatively to 1/60 at final follow-up. Conclusions and importance Autologous Tenon's capsule patch grafting may serve as a useful surgical alternative for large post-vitrectomy macular holes when internal limiting membrane tissue is unavailable.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
