Introduction: Saccadic eye movements are fundamental for interactions with the visual environment. In recent years, there has been interest in verifying whether the use of transcranial direct current stimulation (tDCS) may influence saccadic eye movement. Methods: The aim of this review was to gather data from the scientific literature on the influence of tDCS on saccadic eye movement in adults. In combined with this, it is sought to analyze its relationship with healthy, pathological human aging, performance in ADLs, postural control and cognitive aspects. Results: We found 8 recently published articles that used tDCS as a way to influence the performance of the execution of the saccades. Discussion: It seems that the next steps to be followed need to meet protocols with longer duration of time, with different therapies of ocular training for reflex and active components, with long-term follow-up, with the exploration of new cortical regions as a target and with evaluation of the influence of these treatments on functional activities such as gait and activities of daily living.
