Full-thickness macular hole (MH) is a common sight threatening macular condition with a prevalence of 3.3 per 1000 individuals. Prompt surgical repair of MH is imperative in preventing irreversible vision loss from MH as the majority of patients would experience progressive loss of central vision, often resulting in visual acuity (VA) of 20/200 or worse and the spontaneous closure rate is less than 10%. Pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling (with or without ILM flap) and gas tamponade, herein referred to as conventional surgery, is the current standard-of-care surgical technique in repairing MH. Recently, a novel surgical technique that omits the need of gas tamponade to repair MH has been proposed, early results from retrospective studies were encouraging. The purpose of this prospective international multi-centre randomised controlled study is to compare the efficacy and safety of two surgical techniques in treating MH: 1. Conventional surgery: PPV with ILM peeling and gas or silicone oil tamponade 2. ILM flap with no gas tamponade surgery: PPV with ILM flap with no gas tamponade
