Abstract:
For evaluating the change of strength of extraocular muscle after strabismus surgery, ten rabbits had been performed resection of lateral rectus muscle in right eye and recession of lateral rectus muscle in left eye, and then performed EMG(electromyography). We performed EMG before surgery, at immediate post-op,after 1 day,1,2,3,4,6,8 weeks. In case of resection of lateral rectus muscle, EMG value increased at immediate post-op then stabilized after 6 weeks. In case of recession of lateral rectus muscle, EMG value decreased at immediate post-op, then stabo; ozed after 6 weeks. Therefore, EMG is the useful method in evaluating the change of strength of EOM. Especially, during 6 weeks after surgery is the important peeriod for follow-up.
