G. Lennerstrand et al., FORCE DEVELOPMENT AND VELOCITY OF HUMAN SACCADIC EYE-MOVEMENTS .1. ABDUCTION AND ADDUCTION, Clinical vision sciences, 8(3), 1993, pp. 295-305
1. We have recorded horizontal saccadic eye movements with EOG and mea
sured corresponding force development by means of a contact lens-strai
n gauge technique in ten normal subjects. 2. We found that the peak ve
locity of the saccade was higher in adduction than in abduction, while
peak tension and steady-state tension were balanced in the two direct
ions both in the right and left fields of gaze. 3. Amplitude, duration
and peak velocity of the saccade were linearly correlated to the corr
esponding tension parameters within the mnge of 20 deg eye movements.
4. The results show that information of eye muscle force production ca
n be obtained by measurements of horizontal eye movements with EOG, wh
ich is convenient and easy to perform, especially in children. 5. The
results provide a basis for further studies of saccadic movements in p
atients with strabismus of different types.
