Idiopathic Macular Hole Displaced Toward Optic Disc after Vitrectomy with Internal Limiting Membrane Peeling

Kouichi Ohta, Atsuko Sato and Emi Fukui

Purpose: To compare the distance between the optic disc and the fovea (disc-to-fovea distance) before and after a successful closure of an idiopathic macular hole (MH) by pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling.
Methods: This was a retrospective observational study of 37 eyes of 36 patients with a MH that had undergone PPV. The distance between the point of intersection of a blood vessel and the disc margin and the center of the opened or closed MH at 6 months after surgery was measured in the Spectralis HRA+OCT (Heidelberg Engineering, Germany) images.
Results: The mean disc-to-fovea distance was significantly shorter postoperatively than preoperatively (3,783.7 ± 308.5 μm and 3,914.5 ± 320.4 μm, respectively; P<0.0001). The distance in eyes with Stage 3 and 4 MH (n=22) was significantly greater than that in eyes with Stage 2 MH (136.7 ± 134.9 μm vs. 107.8 ± 107.8 μm, respectively; P= 0.012; n= 15).
Conclusions: The significantly shorter postoperative disc-to-fovea distance in eyes with a closed MH especially Stage 3 and 4 MHs suggests that the fovea moves nasally after PPV with ILM peeling.
