Elderly people, especially those with depression, represent the population most at risk for suicide. In addition to commonly used neuropsychological, psychiatric and biological tests, ocular saccadic analysis can be an interesting tool for identifying suicidal behaviors (SB). These SBs could be associated with an alteration of the cortical structures involved in the executive functions. This alteration is particularly manifested by a decrease in the ability to control eye movements (EM). Thus, depressed elderly people with SB may have a greater impairment of oculomotor performance than those without SB. The purpose of this article is to summarize the literature allowing us to support this hypothesis.
