SS-iOCT-guided Pin-style Amniotic Membrane Transplantation

2026-05-09 17:02
In a 25-year-old highly myopic patient with macular hole-induced retinal detachment in the right eye, initial vitrectomy and silicone oil tamponade failed to achieve macular hole closure. Following silicone oil removal, vision declined again. Color fundus imaging revealed extensive peripheral retinal detachment, and OCT showed a persistent macular hole with associated macular detachment.
A novel pin-style biological amniotic membrane (AM) transplantation strategy was performed to repair the recalcitrant macular hole under the guidance of a digital navigation surgical microscope (Focean, TowardPi). Intraoperative OCT provided real-time visualization of the highly detached posterior pole and the precise position of the AM, with one end placed subretinally and the other over the retina, effectively covering the macular hole.
After fluid-air exchange, the membrane position was further fine-tuned under real-time iOCT guidance to optimize surgical outcomes. At two weeks post-op, OCT confirmed AM coverage over the macula, complete macular hole closure, and retinal reattachment.
