To investigate the incidence, clinical features, and outcomes of patients with macular hole (MH) formation after pars plana vitrectomy (PPV) for diabetic tractional retinal detachment (TRD). We conducted a retrospective review of all cases of PPV for diabetic TRD performed by a surgeon (DS) at a large county hospital between November 2013 and August 2016. Ninety consecutive eyes of 79 patients were included in this case series, of which four eyes developed MH, yielding an incidence of 4.4% (95% confidence interval [CI], 1.2%-11.0%). The mean interval between PPV for TRD and MH formation was 7.0 ± 5.5 (mean ± 1 standard deviation) months, and mean follow-up time was 29.6 months ± 6.9 months. Three of the four eyes that developed MH underwent intervention, and of the three that underwent intervention, all had successful hole closure. In this case series, the incidence of MH after PPV for TRD is 4.4% (95% CI, 1.2%-11.0%). The mechanism of MH formation after diabetic TRD repair is not certain but may be related to a taut internal limiting membrane, epiretinal membrane formation, macular edema, or residual vitreous contraction.
