To the Editor: Although the “three-step test” is regarded as the gold standard for diagnosing fourth nerve palsies, there are a number of instances in which its usefulness is diminished, including restrictive ocular myopathies, longstanding strabismus, strabismus surgery, skew deviation, and disorders such as myasthenia where more than one muscle is involved.1 Jacobson et al. used the

[Article in Danish] Authors Elisa Skovgaard Jensen 1 , Steen Nepper-Christensen. Affiliation 1 Elisa.skovgaard.jensen@regionh.dk. PMID: 31538573 Abstract Dysfunction of the fourth cranial nerve (trochlear nerve), which innervates the superior oblique muscle, is one cause of paralytic strabismus and can result from lesions anywhere along its path between the fourth nerve nucleus in the midbrain and the superior oblique muscle within the orbit. These lesions can be congenital or acquired. Trochleitis is an inflammation of the trochlea and peritrochlear region.

1. Introduction. Trochlear palsy is one of the most common causes of acquired strabismus causing vertical diplopia .Since the trochlear nerve innervates the superior oblique muscle which depresses (mainly in adduction) and intorts the eye, the affected eye becomes hypertropic and extorted, resulting in oblique but largely vertical diplopia.
