PURPOSE: To compare the anatomic success between repair of rhegmatogenous retinal detachment (RRD) with superior breaks and repair of RRD with inferior breaks, by performing primary vitrectomy and using similar techniques and the same gas. METHODS: Eighty-two consecutive eyes of 80 patients with RRD were included in this retrospective comparative study. The eyes were divided into two groups according to the location of the breaks: superior (n = 62) and inferior (n = 20). All the patients underwent a standard, 3-port, 20-gauge pars plana vitrectomy with 20% sulphur hexafluoride gas tamponade performed by the same surgeon. The main outcome measured was the primary anatomic reattachment at 3 months after surgery. RESULTS: The primary anatomic success rate in the inferior group was significantly lower than that in the superior group (80% versus 98%, p = 0.012). In the inferior group, the primary anatomic success rate in patients whose symptoms lasted for more than 2 weeks was significantly lower than that in others (5/9 versus 11/11, p = 0.026). Multivariate logistic regression analysis identified inferior break as the only independent risk factor for redetachment (odds ratio, 11.88; p = 0.034). CONCLUSION: The anatomic success of primary vitrectomy for RRD with inferior breaks is lower than that for RRD with superior breaks. In particular, the duration of symptoms longer than 2 weeks is associated with a worse outcome in patients who had RRD with inferior breaks.
