There was no significant difference between GI and GIII in the comparison of saccadic eye movements and optokinetic nystagmus tests, except for the slower movement velocity of the left eye in the group with dyslexia (Table 3).
This study is unique in that the primary measure is saccadic eye movement. Our intention is to examine the pattern of saccadic latency and its relationship to cue location.
Saccadic eye movements and the perception of visual direction.
Overall, the COVS showed excellent accuracy and repeatability for assessing near lateral and vertical phorias, flat fusion (by Worth 4 Dot), fixation, and pursuit and saccadic eye movements. Despite the strong Pearson correlation, the Bland-Altman analysis identified minor to moderate discrepancies for both PFV and NFV and their associated recovery, as well as with the monocular accommodative facility measurements.

The majority of saccadic eye movement studies in the past century have generally employed simple stimuli such as bars, dots, and gratings with different spatial frequencies and small window sizes that affected luminance instead of pattern detection.
When saccadic eye movements consistently fail to land on their intended target, saccade accuracy is maintained by gradually adapting the movement size of successive saccades.

In summary, evidence supports the hypothesis that each of the three factors--identification, gap, and ISR--may exert their influence in reducing saccadic eye movement latency through neural activity involving the PFC.
He had hypometric rapid eye saccadestothe left with fatigue after 3 saccadic eye movements; hyperactive bowel sounds in the LLQand LUQ, hypoactive bowel sounds in the RUQ; tenderness to palpation in the LLQ and McBurney's point, along with a tight diaphragm on palpation.
