Evaluation and Management of Symptomatic Vertical Strabismus and Diplopia

Abstract

ABSTRACT The evaluation and management of vertical strabismus is more challenging and nuanced than that of horizontal strabismus. Vertical strabismus often results from a variety of restrictive or paretic causes, which can be further characterized as either acquired or congenital. In some cases, identifying the correct etiology of the strabismus can mean uncovering a potentially life-threatening condition, such as a brain tumor or stroke. The keys to identifying the correct diagnosis are, first and foremost, a careful history, and secondly, a detailed examination. The characteristics, etiologies, and evaluation of vertical strabismus will be reviewed here.
