Abstract. We operated on 44 cases of congenital superior oblique palsy. Recession of inferior oblique was performed in 28 cases with marked overaction of inferior oblique muscle. The other 16 cases received recession of superior rectus in the affected eye or of inferior rectus in the fellow eye. Magnetic resonance imaging(MRI)was used to identify the presence or absence of atrophy in the muscle belly of suuperior oblique. Outcome of surgery was evaluated by vertical deviation in the primary and head-tilted position and by Hess screen chart.Following recession of inferior oblique,cases without muscle atrophy showed better outcome than those with muscle atrophy(p<0.05). Following rectus muscle recession,there was no difference in the surgical outcome dependent on the presence or absence of muscle atrophy. The findings show that recession of inferior oblique alone may not be sufficient in cases with overaction of inferior oblique and muscle atrophy.
