To describe the structural features of the autologous retinal transplant donor tissue area seen on optical coherence tomography (OCT). This observational prospective study included patients who had vitrectomy and autologous retinal graft surgery for a macular hole. OCT of the donor area was performed in the postoperative period after gas reabsorption (mean, 16.2 days ±9.8 [SD] after surgery; range, 7 to 28 days), and structural findings in the harvest area were recorded and analyzed. Of the 12 eyes included in the series, most showed glial tissue or some migration of the inner nuclear layer (INL) in the donor area. Hyperreflective dots and epiretinal membranes were present in a few cases; 2 eyes showed denuded retinal epithelial pigment. OCT revealed changes in the donor area, predominantly filled with glial tissue, INL migration, and inflammatory signs, that mostly resolved during follow-up.
描述光学相干断层扫描（OCT）上所见的自体视网膜移植供体组织区域的结构特征。这项观察性前瞻性研究纳入了因黄斑裂孔接受玻璃体切除术和自体视网膜移植手术的患者。在气体吸收后的术后阶段（术后平均16.2天±9.8[标准差]；范围7至28天）对供体区域进行OCT检查，并记录和分析取材区域的结构发现。该系列纳入的12只眼中，大多数在供体区域显示神经胶质组织或内核层（INL）的一些迁移。少数病例出现高反射点和视网膜前膜；2只眼显示视网膜上皮色素脱失。OCT显示供体区域有变化，主要为神经胶质组织填充、INL迁移和炎症迹象，这些在随访期间大多消退。
