It is generally regarded as having a benign outcome. We observed 16 children with PTU, from 10 months to 11 years from onset (mean, 5.4 years), to study the natural history and possible etiology. Five cases were from two unrelated families. Onset of PTU occurred either during or after an intercurrent infection or vaccination in 5 children. No antecedent was identifiable in the rest. PTU had completely resolved in 10 children (62%) (mean age at offset, 2.5 years), whereas 2 children intermittently manifest a modified from of the disorder. At follow\u2010up, 11 children (69%) had developmental delay, intellectual disability, or language delay and 9 (56%) had ocular motility problems other than PTU. Only 3 children (19%) had normal development and neurological findings. PTU is a heterogeneous syndrome with respect to associations and outcome and may simply be an age\u2010dependent manifestation of a variety of disorders affecting corticomesencephalic control of vertical eye movement. This disorder may be an early sign of more widespread neurological dysfunction.<\/jats:p>","DOI":"10.1002\/ana.410430416","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T10:15:23Z","timestamp":1104574523000},"page":"514-520","source":"Crossref","is-referenced-by-count":53,"title":["Paroxysmal tonic upgaze: A reappraisal of outcome"],"prefix":"10.1002","volume":"43","author":[{"given":"M.","family":"Hayman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
