Abstract: Idiopathic macular hole after the internal limiting membrane (ILM) is removed during surgery, the intraoperative optical coherence tomography can be used to observe the presence of debris tissue (RF) protruding into the vitreous cavity at the edge of the hole. Current studies suggest that RF may be caused by epiretinal proliferation and vitreomacular traction, but it is still controversial, and the influence of postoperative anatomical and functional recovery is not clear. Common points can still be found, some of the studies suggest that RF is not conducive to postoperative anatomical and functional recovery during the operation, ILM fragments remain on RF tissues after ILM peeling and re-staining. However, in some studies suggest that RF is beneficial to postoperative anatomical and functional recovery, and ILM fragments on RF are removed. This suggests that whether ILM is removed on RF lead to a certain influence on the postoperative efficacy. There are few researches on RF at present, so it is necessary to understand RF from its essence and assist judgment through histological analysis.
