Methods: Two hundred and fifty-nine participants aged between 5 months and 77 years were recruited along the study. All participants underwent a complete ophthalmological assessment. Fixational behavior during long and short fixational tasks was analyzed using a DIVE (Device for an Integral Visual Examination), a digital test assisted with eye tracking technology. The participants were divided into ten groups according to their age. Group 1, 0-2 years; group 2, 2-5 years; group 3, 5-10 years; group 4, 10-20 years; group 5, 20-30 years; group 6, 30-40 years; group 7, 40-50 years; group 8, 50-60 years; group 9, 60-70 years; and group 10, over 70 years. Results: Gaze stability, assessed by logBCEA (log-transformed bivariate contour ellipse area), improved with age from 5 months to 30 years (1.27 vs. 0.57 deg(2) for long fixational task, 0.73 vs. -0.04 deg(2) for short fixational task), while fixations tend to be longer (1.95 vs. 2.80 msec for long fixational tasks and 0.80 vs. 1.71 msec for short fixational tasks). All fixational outcomes worsened progressively from the fifth decade of life. Log-transformed bivariate contour ellipse area (0.79, 0.83, 0.91, 1.42 deg(2) for long fixational task and 0.01, 0.18, 0.28, 0.44 deg(2) for short fixational task, for group 7, 8, 9, and 10 respectively). Stimuli features may influence oculomotor performance, with smaller stimuli providing prolonged fixations. Conclusions: Fixational behavior can be accurately assessed from 5 months of age using a DIVE. We report normative data of gaze stability and duration of fixations for every age group. Currently available technology may increase the accuracy of our visual assessments at any age. 000112756 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/PI14-01568 000112756 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000112756 590__ $$a3.3$$b2022 000112756 592__ $$a0.752$$b2022 000112756 591__ $$aNEUROSCIENCES$$b144 / 272 = 0.529$$c2022$$dQ3$$eT2 000112756 593__ $$aNeuroscience (miscellaneous)$$c2022$$dQ3 000112756 594__ $$a3.9$$b2022 000112756 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000112756 700__ $$aAlejandre, Adrian 000112756 700__ $$0(orcid)0000-0003-4418-7703$$aFanlo-Zarazaga, Alvaro$$uUniversidad de Zaragoza 000112756 700__ $$0(orcid)0000-0003-3161-3793$$aOrtin, Marta 000112756 700__ $$aPerez, Teresa 000112756 700__ $$0(orcid)0000-0003-0060-7278$$aMasia, Belen$$uUniversidad de Zaragoza 000112756 700__ $$0(orcid)0000-0002-1777-0349$$aPueyo, Victoria$$uUniversidad de Zaragoza 000112756 7102_ $$11013$$2646$$aUniversidad de Zaragoza$$bDpto.
