The Effect of Superior Rectus Recession for Dissociated Vertical Deviation (DVD)

ABSTRACT

Dissociated vertical deviation (DVD) is a peculiar clinical entity consisting of an upward and extortional drift of a nonfixating eye. Many different surgical procedures have been advocated for its treatment, but the best approach is still debated. The authors performed superior rectus recession for treatment of DVD in 13 eyes of 8 patients. All patients were followed up for average 15 months after operation. In the vast majority cases, unilateral or bilateral superior rectus recession of graded amounts (7-8mm) was performed. The amount of preoperative DVD was ranged from 10 to 25.6. and the mean effect of surgery was 11 delta. After operation, 46% of the eyes were aligned within good to excellent categories (0-9 prism diopters), and 12 of 13 eyes within fair to excellent results (0-14 prism diopters).
