The diagnostic performance of the frequency doubling perimetry (FDT) C20‐1 screening mode was compared to that of the C20 full‐threshold mode. For the number of defects p < 1% in the total deviation plot, both modes appeared to perform similarly in terms of sensitivity, specificity, and area under the receiver–operating characteristic (ROC) curve. Different cut‐off points should be applied for both modes to obtain equal sensitivity and specificity values, and – related to that – for most subjects more defects were found in full‐threshold mode than in screening mode. For the screening mode, we found a sensitivity of 0.91 and a specificity of 0.88 at a cut‐off point of >0 defects, and an area under the ROC curve of 0.93.
