Abstract

The authors developed a method of measuring the fractal box dimension of the human eyeball movement.We found a fractal property in schizophrenic subjects (n = 20) and normal controls (n = 20). The value of the fractal box dimension for schizophrenic patients differs from the results obtained in the control group.
