Unilateral Inferior Oblique Weakening for the Correction of Hypertropia in Primary Position
Carlos Souza-Dias, M.D.
The authors present their experience with the correction of hypertropia in primary position by unilateral inferior oblique weakening, in patients who have inferior oblique overaction of only one eye or a marked overaction in the hypertropic eye and only a mild overaction in the other eye. In 19 patients who had a recession of the inferior oblique, they achieved an average correction of 8.4 PD +/- 4.0 PD of the hypertropia. There was no increase in or new development of an inferior oblique overaction in the non-operated eye. In seven patients who presented with a decompensated. DVD with a large hypertropia and amblyopia, they performed a unilateral anterior transposition of the affected eye. They achieved an average correction of 20.3 PD of the hypertropia and a mild limitation of elevation of the operated eye. No patient had a post operative hypotropia.

Unilateral weakening of the inferior oblique is a good procedure for correcting hypertropia, provided that certain restrictions are observed.
