Optimizing latency calculation for robust evaluation of the pupillary light response in chromatic pupillography
The use of the intersection of a linear fit through the baseline with a linear fit containing an adjusted number of data points adapted to the characteristics of the pupillary contraction phase appears to be suitable to provide consistent latency calculation, particularly for small constriction amplitudes and noisy data as they may occur in patients with e.g. hereditary retinal degenerations. The evaluation of mean latency per eccentricity is equivalent and may be advantageous in difficult clinical test results with low amplitudes.
