Study of the relationship between eye movements and the geometry of fovea

Abstract

The objective of this research was to compare the features of the shape of the foveolar area with the characteristics of eye movements in reading. To measure the size of the fovea, we used the method of optical coherence tomography of the retina. Based on this method, the diameter of the upper part of fovea (fovea diameter) and fovea bottom (foveola diameter) were determined. We found a negative correlation between the fovea diameter and fixation duration and positive correlations at the level of tendency between the foveola diameter and the number of saccades performed and between the foveola diameter and the number of characters captured by eye per fixation.
