“…15 Moreover, numerous reports cite acquired esotropia of divergence insufficiency type as the presenting sign of a Chiari I malformation. 12,[16][17][18][19][20][21][22] Our patient population supports this finding as three patients were identified as having divergence insufficiency secondary to a Chiari Malformation (type I). Thus, the investigation of any acquired esodeviation warrants a careful inspection for nystagmus, particularly downbeat nystagmus.…”

“…Acquired esotropia due to posterior fossa tumours, tonsillar ectopia, and hydrocephalus, also termed ''divergence insufficiency'' or ''divergence palsy'', is well recognised. 3,6,7 The mechanism underlying this may be abducens palsy or raised intracranial pressure, but can occur in the absence of either. 2 Cerebellar esotropia may also arise from excessive convergence tone, 4 i.e., as a supranuclear phenomenon possibly resulting from disruption to the central vestibular system.…”

“…1 Esotropia has also been described in other posterior fossa structural lesions, Arnold-Chiari malformations, and degenerative cerebellar disease. [2][3][4][5][6][7] The pathogenesis of the esotropia is controversial and may be a result of disruption to central vestibular pathways. 8 We report a prospective observational case series of seven adults with diplopia due to ''cerebellar'' esotropia.…”

“…3 These cases may present with an A-pattern, co-existing nystagmus and hydrocephalus. Arnold-Chiari malformations sometimes do not manifest until late childhood or adulthood, and can be mild.…”
