dc.description.abstractAn individual's ability to see and function visually is determined largely by the relative contributions of a number of underlying components of vision designated as visual abilities. These visual abilities are: acuity, visual field, motility, brain functions, and light and colour reception others consider also contrast, accommodation, and binocular vision. The efficacy of our visual system influences the way we collect and process information. It is through the conjugated movement of the two eyes that we can fix and pursue one object. The ocular movements and the binocular vision are linked and they are influenced mutually. The measurement device most often used for measuring eye movements is commonly known as an eye tracker. In order to characterize the mechanisms of fixation and persecution and the way how binocular vision influences them, we use in our study the Eye Tracking System-ASL 504, because allows an evaluation next to the natural conditions. Our sample was composed by young adults, distributed in two groups, one formed by individuals with normal binocular vision evaluated in two different conditions (binocular and monocular) and another one by individuals with convergence insufficiency, both with 24 participants. The individuals observe a small target, moving in four directions (left-right; right-left; up-down; down-up). The selected variables were: the mean duration of the fixation and mean saccadic amplitudes. The study of normality seems to indicate that the Eye Tracker is an efficient system for the study of ocular movements (fixation and pursuit). The eye-tracking system that we use showed good discrimination for the selected variables. We think that this study shows the important contribution that eye tracking can give in the analysis, of the functional alterations of binocular vision because allows us to evaluate them in conditions very next to reality.pt_PT
