Displacement of fovea toward optic disk after macular hole surgery with internal limiting membrane peeling

Abstract

Kouichi Ohta, Atsuko Sato, Nami Senda, Emi Fukui Department of Ophthalmology, Matsumoto Dental University, Shiojiri, Nagano, Japan Purpose: The purpose of this study was to demonstrate a displacement of the foveal depression toward the optic disk after idiopathic macular hole (MH) surgery with internal limiting membrane (ILM) peeling.Methods: Two patients with a unilateral MH developed an MH in the fellow eyes. Vitrectomy with ILM peeling was performed on the fellow eye to close the MH. Images of spectral-domain optical coherence tomography (SD-OCT) were used to measure the disk-to-fovea distances pre MH formation, after MH formation, and 6 months after the closure of the MH.Results: The disk-to-fovea distance was shorter at 6 months than after the development of the MH (4,109 µm and 4,174 µm in Case 1 and 4,001 µm and 4,051 µm in Case 2).Conclusion: These results indicate that the fovea moves nasally after the MH surgery with ILM peeling.
