Abstract

Purpose : To determine the correlation between the focal macular ERGs (FMERGs) and the microstructural changes of the photoreceptors after successful surgery for fovea-off rhegmatogenous retinal detachment (RRD).

Methods : Twenty eyes of 20 patients that had undergone successful surgery to reattach the fovea in eyes with RRD at the Nagoya University Hospital were studied. FMERGs and SD-OCT were recorded at 1 and 6 months after the surgery. The changes of the values of the different components of the FMERGs, and the morphological changes of the SD-OCT components including the length of the external limiting membrane (ELM), ellipsoid zone (EZ), the cone interdigitation zone (CIZ), and the size of the outer photoreceptor area were determined.

Results : During the postoperative period, the mean amplitudes of the a-waves increased by 1.4 times and the b-waves by 1.7 times. SD-OCT showed that the mean length of the EZ and CIZ and size of outer photoreceptor area had increased significantly at 6 months. The degree of increase of the CIZ and outer photoreceptor area were significantly correlated with the increase in the amplitudes of b-waves of the FMERGs (r=0.64, P<0.05 for CIZ and r=0.57, P<0.05 for photoreceptor areas; Spearman rank correlation test). However, the length of the EZ was not significantly correlated with the increase of the b-waves.

Conclusions : The restoration of the EZ alone was not enough to improve the visual function, and of the restoration EZ accompanied with CIZ was related to the recovery of the FMERGs after a reattachment of fovea-off RRD.
