Dissociated vertical deviation: associated findings and results of surgical treatment

The records of 80 consecutive patients with dissociated vertical deviation (DVD) were reviewed. The most frequent initial problem was esotropia, which was noted before 12 months of age in 67 patients. Latent nystagmus was present in 13 patients, and poor stereopsis was documented in 11 of the 29 patients tested. Resection of the inferior rectus muscle, the most frequent surgical procedure in this series, seldom resulted in total resolution of the DVD, but it often yielded cosmetic improvement.
