Abstract:
AIM:To evaluate 23G vitrectomy for macular edema in eyes with retinal vein occlusion (RVO) combined with vitreoretinal traction (VMT) or epiretinal membrane (ERM).METHODS:Totally 22 patients (22 eyes) diagnosed with macular edema of RVO combined with VMT or ERM were retrospectively analyzed.Twelve cases performed with 23G vitrectomy together with peeling of inner limiting membrane (ILM) and/or ERM were considered as the observation group or intervention group.Ten cases without vitrectomy were recruited as control group.The best corrected visual acuity (BCVA) and central retinal thickness (CRT) at baseline, 1, 3 and 6mo were recorded and compared.RESULTS:At baseline, the difference of BCVA and CRT between observation group and control group was not statistically significant (P=0.645, 0.206).After vitrectomy, the BCVA and CRT of RVO patients in observation group were significantly improved compared with baseline at each follow-up (F=2.895, P=0.048;F=16.431, P<0.01).However, the BCVA and CRT in control group remained the same as baseline at every follow-up.Moreover, the BCVA and CRT in observation group were much better than that in control group at both 3 and 6mo after vitrectomy.However, the BCVA and CRT between two groups were not significantly different at 1mo postoperatively.CONCLUSION:The 23G vitrectomy could markedly improve BCVA and reduce CRT in RVO patients with macular edema combined with VMT and/or ERM.
