Resumen
Purpose: To assess eye movements during reading in individuals with central vision loss using eye-tracking technology and an ad-hoc calibration method.
Materials and methods: This pilot case control study included 17 participants (61.7 § 8.8 years), 12 women and 5 men) and 17 controls, matched for age and sex. Two ad hoc computer-based tests were administered to analyze eye movements during a single-letter reading task and con- tinuous reading task, measured using a 60 Hz eye-tracking device.
Results: Individuals with central vision loss showed differences from the control group, with an increase in the number of fixations, saccadic movements, and regressions, whereas the ampli- tude and speed of saccades were lower. This resulted in longer reading times in the study group.
Conclusion: The results revealed lower performance in eye movements skills during reading tasks in patients with central vision loss. Eye-tracking devices allow the objective binocular assessment of eye movements during reading tasks. Our ad-hoc calibration method ensured mini- mal data loss and high validity, enhancing the reliability of the assessments. This information can be used to develop optimal and personalized functional and visual rehabilitation programs.
