In this paper we demonstrate the dynamics of saccadic system functioning in 38 patients with cerebellum tumor (mean age 12.95±2.62 years) undergoing neurocognitive rehabilitation. Eye movements were recorded during the tests on gaze stability and visual counting. After the second session (after the rehabilitation course) we revealed a significant improvement in gaze stability, time of execution and the reduction in the scanpath length during the counting. Our results provide novel evidence for using the eye tracking method as a diagnostic tool in neurooncology.
