Abstract
The purpose of this research lied in studying the structure and function of connective tissue of superior oblique (SO) in rhesus and rabbit. It was an experimental study. Two adult monkeys (rhesus) and five adult rabbits were involved in this study. The gross anatomy of an orbit in each animal was observed. Meanwhile, the fellow orbit was processed with paraffin imbedding and coronal serial section. Masson trichrome stain was used to distinguish muscle and collagen, and Weigert stain was performed for identification of elastin. Connective tissue around SO in both mammals thickened anteriorly, reflected in the trochlea along with the SO tendon, and became contiguous with the nasal aspect of the SR connective tissue ring, while the tendon passed inferior to the SR pulley to insert on the sclera. The contraction of SO OL can cause SR shift nasally. This may explain the mechanism of vestibulo-ocular reflex (VOR) partly.
