Macular hole (MH) is a common condition that affects approximately 1.6/1000 elderly Chinese population. The prevalence is expected to be even higher in individuals with high myopia (HM), an established risk factor for MH. Without prompt surgical intervention, it can lead to irreversible vision loss and retinal detachment. Standard MH surgery involves pars plana vitrectomy (PPV) with internal limiting membrane (ILM peeling), followed by endotamponade agents to appose the MH edge. Office of Research and Knowledge Transfer Services Common endotamponade agents include intraocular long-acting gas and silicone oil. The use of endotamponade has its limitations, for example, impairing vision, the need for strict posturing and avoid air travel in the early postoperative period. Ocular complications, such as uveitis, cataract and glaucoma may arise. To overcome these shortcomings, a novel technique to close MH without endotamponade agents was proposed by a group from Poland. Using viscoelastics to stabilize ILM flap over the MH, negating the need and limitations of endotamponade agents. However, this case series is limited by its small sample size (12 eyes) and lack of patients with pathological myopia (PH). PH is prevalent in the Asian population and myopic MH tend to have lower surgical success rate due to antero-posterior traction from posterior staphyloma and long axial length associated with PH. There is currently a gap in evidence whether this novel surgical technique could benefit eyes with myopic MH. The investigators plan to conduct a prospective interventional case series to establish the efficacy and safety of myopic MH closure using this novel surgical technique.
