Acute-Onset Vitreous Hemorrhage of Unknown Origin before Vitrectomy: Causes and Prognosis

Figure 3

ROC curves of the scoring system used to predict the visual prognosis of acute-onset VH of preoperatively unknown origin. The solid line shows the ROC curves of four variables (age, baseline BCVA of the affected eye, baseline BCVA of the unaffected eye, and age-related macular changes in the fellow eyes), which were significantly associated with poor visual acuity following vitrectomy. The dashed line shows the ROC curve of the scoring system. The AUC of the scoring system was 0.907 (95% CI = 0.853–0.948).
