Algorithm for the multi-parameter analysis of nystagmus using a digital computer.
A computer program for analyzing nystagmus has been developed and can be used on a small laboratory digital computer. The algorithm accepts digitized data and looks for the minimum and maximum (minmax) points of the nystagmus waveform. These points in turn are used to define seven descriptive parameters of nystagmus, including the amplitude, duration, and velocity of the slow and fast phases, and the frequency. The algorithm uses three user-adjusted criteria for accepting or rejecting minmax points. The treatment of noisy or irregular data can be improved by adjusting the values of these criteria.
