    It is challenging to achieve surgical closure of a long-lasting large macular hole. This video demonstrates a modified technique for covering a macular hole with a single-layered internal limiting membrane (ILM) flap using perfluoro-n-octane (PFO). An ILM flap of about one disc in diameter is used to cover the macular hole from its superior margin. The temporal and nasal ILM is removed separately from inferior to superior to remain the designated area for a flap. PFO is introduced over the macula to keep the inverted ILM flap in the position during surgery and is removed at the end of fluid-air exchange.
