Pseudoparalysis caused by anomalous insertion of superior rectus muscle.
Congential ectopia of the insertion of the superior rectus muscle to the superior border of the lateral rectus muscle was seen in a 4-year-old child. In all respects, this condition mimicked congenital superior rectus palsy. The resultant large hypotropla was completely corrected by repositioning the superior rectus to its normal anatomic position.
