Influence of JA on the sensitivity and specificity in error analysis. Influence on the results of error analysis of changing JA using the contingency table (Table 2). Previous studies using normal-field fundus cameras suggested that 10 DA is the threshold of NV occurrence, but more recent studies using UWF suggest that 30 DA, or even 50 DA, is the threshold. Here, sensitivity and specificity remained at almost 80% until around 30 DA.
