ABSTRACT

AIM:To evaluate two structural predictors of visual outcome of epiretinal membrane surgery.METHODS:Retrospective study for 30 eyes of epiretinal membrane surgery between January 2014 and October 2016.We assessed the related parameters of the optical coherence tomography and recorded the best-corrected visual acuity(BCVA) at baseline and 1,3 and 6mo after surgery.Correlations between the final best-corrected visual acuity and photoreceptor integrity status or photoreceptor outer segment length were investigated.RESULTS:Average best-corrected visual acuity decreased at 1mo postoperatively compared with baseline,but improved at 3 and 6mo.Central macular were more sweller at 1mo postoperatively than baseline,but a significant thickeness reduction was found at 6mo (P＜ 0.05).Photoreceptor outer segment length were shortened at 1 mo compared with preoperation (P＜0.05),gradually approached the baseline level at 3 and 6mo.Multivariate regression the final best-corrected visual acuity associated with photoreceptor integrity and photoreceptor outer segment length (P=0.023,0.004).CONCLUSION:Photoreceptor integrity and photoreceptor outer segment length detected by OCT were significant predictors of the final best-corrected visual acuity(BCVA) after idiopathic epiretinal membrane surgery.
