ABSTRACT

La parálisis de convergencia se caracteriza por la imposibilidad de la convergencia en la mirada próxima, con diplopía horizontal cruzada a partir de 1 metro, con aducción normal. La parálisis de la convergencia es una condición distinta de la insuficiencia de la convergencia y normalmente secundaria a una lesión intracraneal. Acude paciente de 12 años de edad por presentar diplopía horizontal de cerca ± 1 metro de 3 meses de evolución, cefalea, lagrimeo y fotofobia. La impresión diagnóstica fue parálisis de convergencia. En los estudios neurológicos solo se encontró implantación baja de las amígdalas cerebrales. Aún no se precisa la etiología aunque se recoge el antecedente de un traumatismo craneal sin relevancia por la familia


The convergence paralysis is characterized by impossible convergence in the near sight, with crossed horizontal diplopia at one meter distance and normal adduction. The convergence paralysis is a condition different from the inadequate convergence and usually secondary to intracranial lesion. A 12-years old patient went to the hospital because he had suffered horizontal diplopia in near sight (± 1 meter) for 3 months, migraine, watering and photophobia. The definitive diagnosis was convergence paralysis. In the neurological studies, the low placing of the tonsils of cerebellum was the only finding. The etiology of this disorder is not determined yet; although there is some history of head trauma to which the family did not pay enough attention
