Changes in Eye-Tracking Metrics in Patients with Central Nervous System Lesions Following Oculomotor Rehabilitation: A Pilot Study
Year: 2026
Type: conference-paper
Study design: Clinical Trial
Abstract: Visual and oculomotor impairments are common in stroke patients and significantly impair the effectiveness of rehabilitation and daily functioning. This study evaluates the effectiveness of visual-oculomotor rehabilitation using the C Eye PRO eye tracker, which utilizes eye movement control and visual biofeedback. The study included 20 stroke patients with various visual and eye movement impairments who underwent training, during which binocular gaze coordinates were recorded under static and dynamic conditions of a fixation test. From the oculographic signals, features characterizing the percentage of gaze hits on target during static and dynamic conditions (STAT%, DYN%) were extracted, as well as changes in these features between two time points before and after rehabilitation, including subgroups based on the presence of diplopia, nystagmus, and stroke type. Both parameters were shown to increase on average after a rehabilitation course, with the dynamic DYN% indicator demonstrating the greatest increase in patients with diplopia and nystagmus and better differentiating groups by stroke type than STAT%. The obtained results indicate the potential of simple quantitative metrics based on eye-tracking data as sensitive markers of the effectiveness of visual-oculomotor rehabilitation and justify the need for further research with an expanded set of parameters and an increased sample size.
