| Abstract |
PURPOSE
Because the ipsilateral superior rectus (SR) and superior oblique (SO) muscles are innervated by two different nerves, it is very rare for these two muscles to be paralyzed while all other extraocular muscles function normally. The authors experienced a case where the patient had a loss of intorsion (action of both SR and SO muscles) and also loss of SO muscle's infraduction and adduction, and SR muscle's supraduction and abduction. The authors studied how such loss of function affects extraocular movement. METHODS: A 63-year-old male patient who had his SR and SO muscles severed by a saw was admitted to the hospital after getting rid of the two exposed muscle which were attached to the eyeball due to failure of reconstruction of two muscle. The patient was followed up for 8 months, and at the end of the follow-up period, the angle of deviation was measured while double Maddox test and fundus examination were also performed. RESULTS: At primary position there was extorsion of 7 degrees as well as esodeviation of 6 PD and hypodeviation of 6 PD on the left eye, and we hereby report the case. |
