[Dissociated vertical divergence. Early strabismus. Nystagmus].

Abstract

The presence of a DVD makes the ocular motility examination complicate but it is a valuable sign for the clinician as it is noticed essentially in infantile early onset strabismus with latent nystagmus. It is fundamental not to confuse it with an hyperaction of the inferior oblique. It requires a surgical treatment: a recession of superior recti.
