Michalewska Z, et al. - Researchers evaluated the impacts of repeat surgery in failed primary full-thickness vitrectomy for macular hole (FTMH) closure with the inverted internal limiting membrane (ILM) flap technique. They noted that the repeat surgery with the inverted ILM flap technique was an effective method of treatment. After the second surgery, the anatomical outcome was improved by the silicone oil but the visual results were not influenced. Final visual results were not influenced by the tamponade used (either silicone oil or air).
