摘　　要：Purpose:To assess the rate of occurrence and the risk factors of postsurgical macular edema(PSME)in eyes with idiopathic epiretinal membrane(iERM)or full-thickness macular hole(FTMH).Methods:Retrospective longitudinal analysis of all subjects scheduled for vitrectomy with or without combined cataract surgery over a 6-month period.Electronic medical charts and imaging data were analyzed preoperatively and at 1,3 and 6 months after surgery.Results:From 101 patients diagnosed with iERM or FTMH,71 patients were eligible for the study.Forty-nine eyes with iERM(69.0%)and 22 eyes with FTMH(31.0%)underwent vitrectomy either isolated(31.0%)or combined with cataract extraction(69.0%).The overall rate of PSME was 26.7%,without differences between the two groups(P=0.9479).Combined cataract extraction did not affect the overall occurrence of PSME rate in both groups(P=0.9255 in FTMH and P=0.8658 in iERM).If grouped by stage,eyes with stage 4 iERM though disclosed an increased rate of PSME(57.1%)compared to lower(1 to 3)stages(14.3%,P=0.0021),particularly when combined with cataract surgery(71.4%vs.15.4%in stages≤3,P=0.0021).The PSME odds ratio for a stage 4 iERM is 8(95%CI:1.933-33.1;P=0.0041)compared to stages 3 and below.Conclusions:PSME remains a clinically relevant and frequent event after surgery for iERM and FTMH.Patients with stage 4 iERM have an 8-fold higher likelihood of developing PSME in a 6-month postsurgical period compared to iERM in 1-3 stages,especially when combined with cataract extraction.
