Hypotropic Dissociated Vertical Deviation: A Unique Form of Dissociated Strabismus Complex

Hypotropic DVD is mostly unilateral and commonly is associated with monocular visual deficits or high myopia. Although the nature of the intermittent slow downward ocular deviation is similar to that of hypertropic DVD, it should be considered to be a unique form of the dissociated strabismus complex. This rare condition can be corrected surgically by a large recession or a combined recession-resection of the inferior rectus muscle.
