The analyse of the effect in macular preretinal membrane surgery

Abstract

Objective To study the effect of surgery on macular epiretinal membrane by vitrectomy with inner limiting membrane peeling.Methods The changes in visual function and complications of surgery in 45 cases with macular preretinal membrane before and after surgery were analysed.Results Followed up 3 ～ 10 months,45 cases(45 eyes) included idiopathic macular epiretinal membrane in 23 eyes and secondary epimacular membrane in 22 eyes.In 23 eyes with idiopathic macular epiretinal membrane,preoperative visual acuity was less than 0.3 in 15 eyes (65.2％),better than or equal to 0.3 in 8 eyes (34.8％) ;postoperative visual acuity was less than 0.3 in 9 eyes(39.1％),better than or equal to 0.3 in 14 eyes (60.9％).In 22 eyes with secondary macular epiretinal membrane,preoperative visual acuity was less than 0.05 in 18 eyes(81.9％),postoperative in 12 eyes(54.6％) ; preoperative was better than or equal to 0.05 in 4 eyes (18.1％),postoperative in 10 eyes(45.4％).The postoperative visual acuity improved in both groups.Metamorphosia disappeared in 37.5％,improved in remainder.The serious complications of the surgery included macular hole in 2 eyes.Conclusion Vitrectomy with inner limiting membrane peeling is effective treatment for macular epiretinal membrane.
