To determine whether there is a movement of the fovea after successful macular hole (MH) surgery with internal limiting membrane (ILM) peeling.
Spectral-domain optical coherence tomography (SD-OCT) was performed before and >3months after the surgery. The preoperative distances between the center of the MH and optic disc (MH-OD), center of macular hole and bifurcation or crossing of retinal vessels (MH-RV), and 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.
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±0.16 DD to 0.79±0.15 DD; P<0.001), the inner temporal area (from 0.82±0.15DD to 0.77±0.14 DD; P<0.001), and outer nasal area (from 1.70±0.31 DD to 1.65±0.32 DD; P<0.001), but was significantly longer than the MH-RV in the outer temporal area (from 1.65±0.29 DD to 1.68±0.29 DD; P=0.006). In eyes with a spontaneous closure of the MH, the “MH-OD and F-OD” and “MH-RV and F-RV” were not significantly different.
Our results showed that successful closure of a MH by vitrectomy with ILM peeling and gas tamponade results in a movement of the center of the macula toward the optic disc.
