Analysis of the SLO data.
retinal movements
RETINA
The retina and the stimulus (here the character cat 猫) are seen upside down only by the examiner. The stimulus is seen upright by the child. The Chinese character is fixated with the fovea.A total of 58,694 half-frames (eye coordinates) were included in our analysis, which was a very time-consuming procedure. In order to determine the fixation location, we used custom-designed image analysis software that tracks the position of a user-defined landmark, e.g. a retinal vessel branching. This detects retinal movements and allows determining the coordinates of the fovea relative to the image of the stimulus, both of which are visible on the image of the retina (After separate analysis of the eye movements by both methods, we found good agreement between the data and therefore, we combined them.
