Abstract:
AIM: To explore the correlation between the integrity of the macular microstructures and the visual outcomes before and after idiopathic macular epiretinal membrane(IMEM)surgery.METHODS: A total of 43 patients(43 eyes)with IMEM who were treated in our hospital between January 2017 and December 2019 were selected. The best corrected visual acuity(BCVA)of each patient was examined preoperatively and at 3, 6, 9mo after surgery. Moreover, metamorphopsia(M-chart)examination was given, and spectral domain-optical coherence tomography(SD-OCT)was used to measure central foveal thickness(CFT), subfoveal choroidal thickness(SFCT), the thickness of ganglion cells-inner plexiform layer(GC-IPL)and the length of interdigitation zone(IZ)defect.RESULTS: The BCVA and the metamorphopsia were gradually improved at postoperative 3, 6 and 9 mo(all P<0.05). Moreover, the BCVA was positively correlated with CFT and the length of the IZ defect(P<0.05), while it was not correlated with SFCT and the thickness of GC-IPL(P>0.05). The metamorphopsia assessment was positively correlated with the CFT at postoperative 3, 6, and 9mo(P<0.05), while it was not correlated with SFCT, the thickness of GC-IPL and the length of IZ defect(P>0.05).CONCLUSIONS: The CFT and the length of IZ defect were significantly correlated with the BCVA after IMEM surgery, which can be used as indicators to predict the recovery of visual function after IMEM surgery.
