Abstract PURPOSE: To determine whether there is a displacement of the fovea toward the optic disc after successful macular hole (MH) surgery with internal limiting membrane (ILM) peeling. METHODS: The medical records of 54 eyes of 53 patients that had undergone pars plana vitrectomy with ILM peeling and gas or air tamponade for an idiopathic MH were evaluated. Spectral-domain optical coherence tomography (OCT) had been performed before and >6 months after the surgery. The preoperative distances between the center of the MH and the optic disc (MH-OD), center of the MH and the bifurcation or crossing of retinal vessels (MH-RV) were measured in the OCT images. In addition, the postoperative distance between the center of the fovea and optic disc (F-OD) and the center of the fovea and the same bifurcation or crossing of retinal vessels (F-RV) were measured in the OCT images. RESULTS: The F-OD was 2.67±0.33 disc diameters (DD), which was significantly shorter than that of the MH-OD of 2.77±0.33 DD (P<0.001). The F-RV was also significantly shorter than the MH-RV on the inner nasal area (from 0.85±0.16DD to 0.79±0.15DD; P<0.001), the inner temporal area (from 0.82±0.15DD to 0.77±0.14DD; P<0.001), and outer nasal area (from 1.70±0.31DD to 1.65±0.32DD; P<0.001), but it was significantly longer than the MH-RV in the outer temporal area (from 1.65±0.29DD to 1.68±0.29DD; P<0.001). CONCLUSION: Our results showed that successful closure of a MH by vitrectomy with ILM peeling and gas tamponade leads to a displacement of the center of the macula toward the optic disc.
