25gauge vitrectomy combined with companded internal limited membrane peeling for idiopathic macular hole

Objective To observe the effect of 25gauge vitrectomy combined with companded internal limited membrane peeling for idiopathic macular hole.Methods Twenty cases (20 eyes) with idiopathic macular epiretinal membrane diagnosed by optical coherence tomography,fluorescence fundus angiography,central visual field,fundus photography.All cases underwent three ports vitrectomy using 25gauge Transconjunctival Sutureless Vitrectomy System.Companded internal limited membrane peeling was conducted with 25g intraocular forceps with the help of staining of Indocyanine green.All patients were temponaded with C3F8.The operation time,postoperative BCVA,central visual field,the healing of maeular hole were observed.Follow-up was 6-12 months,meanly 8 months.Results The operation lasted for 12-18minutes,meanly 15 minutes; Among them,the BCVA was 0.1-0.3 in two eye,＞0.3-0.5 in eight eyes,＞0.5-0.8 in ten eyes; In all patients,central scotoma occurred in 2 eyes,paracentral scotoma in I eye in the last follow-up.Macular holes were closed in nineteen eyes,while one macular hole was closed partly.Condusions 25gauge vitrectomy combined with companded intemal limited membrane peeling is effective in treatment for idiopathic macular hole,it can promote visual acuity,shorten operation time,make metamorphopsia better,decrease complication.
