Idiopathic macular hole (IMH) is a fundus disease without clear etiology, most often seen in healthy women over 50 years of age, and is often associated with ocular manifestations such as loss of central vision and visual distortion. It is often associated with loss of central vision, visual distortion, and other ocular manifestations. It is currently treated by vitrectomy combined with internal limiting membranes (ILM) peeling followed by gas filling. A strict prone position for a certain period of time after surgery has a positive effect on the healing of the macular fissure. The need for a strict prone position after IMH has been demonstrated in previous studies (especially when the IMH diameter is \>400 μm). However, due to the anti-human mechanics of the face-down position, patient comfort, sleep quality and quality of life are greatly compromised. Therefore, this study designed a smart head position monitoring device to assist patients in maintaining the correct position and recording the effective position time. The study was conducted to determine the shortest prone position time based on macular fissure closure, to minimize the adverse effects of postoperative position, and to obtain the maximum recovery of visual acuity and visual field.
