Abstract:
Objective:To investigate the changes of macular region structure before and after operation in patients with macular epiretinal membrane,and its relationship with the visual function of patients.Methods:The clinical data of 60 patients with macular epiretinal membrane (60 eyes) in our hospital from February 2014 to August 2016 were retrospectively analyzed.All patients were examined with optical coherence tomography (OCT) examination,and observed the changes ofmacula central fovea and retinal each azimuth thickness,and the best corrected visual acuity (BCVA) was recorded before and after operation,and the correlations of them were analysised.Results:The visual acuity was improved in 53 patients (53 eyes) after operation,accounting for 88.33％,and the visual acuity was unchanged in 7 patients (7 eyes),accounting for 11.67％.The preoperative BCVA of patients was (0.18± 0.07),and it was (0.38± 0.12) at 3 months after operation,which was significantly higher than before operation (P＜0.05).Postoperative macular central thickness,inner side of the inner ring thickness,nasal side of the inner ring thickness,above the inner ring thickness,below the inner ring thickness,outer ringtemporal side thickness,external ring nasal side thickness,above the outer ring thickness,below the outer ring thickness in patients compared with the preoperative were significantly lower,the difference was statistically significant (P＜0.05).The Pearson correlation analysis showed that preoperative macular central thickness,preoperative inner side of the inner ring thickness,preoperative outer ring temporal side thickness,the difference of macular fovea thickness before and after operation,the difference of the medial temporal before and after operationwas,the difference of outer ring temporal side before and after operation were negatively correlated with postoperative BCVA (P＜0.05).Conclusion:Vitrectomy can significantly reduce macular retinal thickness in patients with macular epiretinal membrane,and it can improve the visual function of patients,and the shape ofmacular region before operation had some influence on postoperative visual acuity.
