Abstract

Purpose : Displacement of the macula was reported using various modality after surgical closure of macular hole. However, displacement of the fovea has not been investigated due to lack of the reference. The purpose of the current study was to investigate postoperative displacement of the retinal layers of the fovea by comparing to the choroid in en face image after macular hole surgery.

Methods : We reviewed retrospectively the medical records of the patients having macular hole that was closed surgically. En face images of optical coherence tomography were exported at the level of the choroid, ellipsoid zone (EZ), and inner plexiform layer (IPL) at baseline, 1, 3 and 6 months. The foveal center of the EZ and IPL was marked in the en face image of the choroid. The choroidal images were overlapped to match the vasculature in each patient, and the postoperative displacement of the foveal center was calculated comparing to the baseline.

Results : Seventeen patients were included in the study. The center of the EZ and IPL displaced to the disc continuously for 6 months. The mean horizontal displacement was 27, 81 and 101 µm for the EZ (P = 0.117 - 0.001) and 48, 63 and 113 µm for the IPL (P = 0.004 - 0.001) at 1, 3 and 6 months, respectively. No significant difference was found in the location of the foveal center between the EZ and the IPL.

Conclusions : The concurrent displacement of the photoreceptor layers and inner retinal layers was observed after surgical closure of the macular hole. These findings suggest that displacement of the photoreceptors would be important mechanisms for postoperative metamorphopsia.
