Abstract

In twenty five patients with vertical strabismus including dissociated vertical deviation, the auther measured the width of the superior rectus muscle insertion and the distances from posterior limbus to nasal, middle and temporal portion of the superior rectus insertion. The means of width of the insertion was 9.8mm +/- 0.92, the distances from the posterior limbus to the nasal, middle and temporal portion of the superior rectus insertion were 7.2mm +/- 0.92, 6.9mm +/- 0.7, and lO.8mm +/- 1.0 (in 7 cases) respectively. Statistically, the means of these measurements of DVD were not significantly different from other vertical strabismus patients. These reults suggest that the etiology of the DVD is not anatomic but neurogenic in origin.
