Quantitative Approach for the Analysis of Fusional Convergence Using Eye-Tracking and SacLab Toolbox

Figure 1

Example of eye movement recordings with ET system and automatic analysis implemented in SacLab to derive the descriptive parameters for fusional response. (a) Analysis of vergence response: identification of convergence using a threshold-based algorithm (Th₁C, Th₂C) and calculation of convergence parameters (CD = convergence duration; CA = convergence amplitude; and CPV = convergence peak velocity). (b) Analysis of version response: identification of intrusive saccades using a threshold-based algorithm (Th₁S, Th₂S) and calculation of saccadic parameters (NS = number of intrusive saccades; MSA = mean saccadic amplitude).
