概要	Purpose Generally, it is rare to experience the macular hole formation after vitrectomy of non-macular hole cases. In this study, we investigated the surgical outcome of the macular hole formed after vitrectomy. Patients and Method We reviewed retrospectively the clinical record of the macular hole cases which received vitrectomy in Kansai Medical University and Yamada Eye Clinic during the period of January 2006 and November 2013. From these cases, we recruited the cases, which the macular hole formed after vitrectomy. All the recruited cases were performed vitrectomy and gas or air tamponade with complete internal limiting menbrane (ILM) removal as the macular hole treatment. We investigated the kind of original disease to perform primary vitrectomy and its method. Then we statistically compared the best corrected visual acuity (BCVA) at the first visit, after primary vitrectomy, macular hole onset, 3 months after macular hole surgery, and last visit. Results The macular hole formed after vitrectomy were 14 cases (8 male and 6 female, average age was 63.2 ranged from 42 to 79). Mean period after primary vitrectomy to macular hole onset was 17.6 months. Mean observation period after macular hole surgery was 25.7 months. The original disease consisted from 5 cases of rhegmatogenous retinal detachment, 3 cases of diabetic macular edema, 3 cases of epi-retinal membrane, each one case of proliferative vitreoretinopathy, proliferative diabetic retinopathy, and macular retinoschisis. Ten out of 14 eyes were operated without removing ILM at the primary vitrectomy. In 2 cases, although ILM was removed in primary vitrectomy, ILM found remained in the macular hole surgery. The macula hole closed successfully in all cases after macular hole surgery. BCVA after primery vitrectomy(p=0.021) and final visit(p=0.038) were statistically better than that of macular hole onset.
