| Research Abstract |
(1) The 2-dimensional coordinates of the position of the rectus pulley in normal Japanese subjects were calculated by MRI image analysis, and the pulley position was stable with small variation among the subjects. It was also shown that the influence of the standard surgery for strabismus on the pulley was small, but special surgery had an influence.
(2) The incidences of morphological abnormalities of the tendon and trochlea and muscle belly hypoplasia in the superior oblique tendon in superior oblique palsy were higher in congenital than in idiopathic cases.
(3) Excycloduction was noted in the pulley position on the side with superior oblique palsy, compared to that in the normal subjects, suggesting an increased mechanical influence of oblique muscle dysfunction, being responsible as a causative factor of incomitant strabismus.
