Surgical results in dissociated vertical deviations.

The effect of surgery on dissociated vertical deviations was compared in three groups of patients treated with one of the following methods: posterior fixation sutures of the superior rectus, superior rectus recession, or superior rectus recession with posterior fixation sutures. Treatment with conventional superior rectus recession combined with posterior fixation sutures (at 12 + mm) resulted in cosmetically acceptable alignment in 88% of eyes. A standard superior rectus recession alone was less dependable. Treatment with posterior fixation sutures of the superior rectus without recession was effective in only 31% of cases after long-term observation.
