Trail-Traced Threshold Test (T4) With a Weighted Binomial Distribution for a Psychophysical Test

Clinical visual field testing is performed with commercial perimetric devices and employs psychophysical techniques to obtain thresholds of the differential light sensitivity (DLS) at multiple retinal locations. Current thresholding algorithms are relatively inefficient tough get satisfied test accuracy, stability concurrently. Thus, we propose a novel Bayesian threshold method called Trail-Traced Threshold Test (T4), which can better address dependence initial estimation achieve significant improvement in accuracy variability while also decreasing number presentations compared Zippy Estimation by Sequential Testing (ZEST) FT. This study compares T4 ZEST FT regarding presentation number, mean absolute difference (MAD between real Visual result simulate result), measurement variability. uses complete response sequence spatially weighted neighbor responses precision than ZEST, FT, SWeLZ, significantly fewer stimulus presentations. more robust inaccurate other methods, an advantage subjective such as clinical perimetry. has potential for using tests.
