Surgical Effect of Transposition for Double Elevation Paralysis

ABSTRACT

The authors have experienced a case of double elevation paralysis with mild degree of hypophoria and exophoria in 10 year-old primary school girl. This case is congenital in origin. Transposition of the insertion of medial and lateral rectus muscle placing the new inserti ons immediately adjacent to the insertion of the superior rectus muscle was performed. After the operation, the subjective symptoms such as diplopia, dizziness, headache were improved even though this does not produce normal elevation beyond the midline level. Double elevation paralysis is caused often by unilateral supranuclear lesion than peripheral congenital lesion.
