ABSTRACT
INTRODUCTION:Tonic pupil or Adie's pupil occurs due to parasympathetic denervation, and it is characterized by mydriasis with little or no response to light, with pupillary contraction to accommodation. It is caused by eye pathologies, such as infections, trauma, neoplasms, inflammatory diseases, and systemic diseases with autonomic dysfunction. Few cases have been reported of bilateral tonic pupils associated with migraine attacks. CASE REPORT: Our aimed to describe the case of a young female patient with a history of chronic migraine without aura, who presented acutely with bilateral pupillary mydriasis during a migraine attack, characterized as tonic pupil, and to discuss the possible causes of mydriasis during a migraine attack.
INTRODUÇÃO: A pupila tônica ou pupila de Adie ocorre devido à denervação parassimpática e é caracterizada por midríase com pouca ou nenhuma resposta à luz, com contração pupilar à acomodação. É causada por patologias oculares, como infecções, traumas, neoplasias, doenças inflamatórias e doenças sistêmicas com disfunção autonômica. Poucos casos foram relatados de pupilas tônicas bilaterais associadas a crises de enxaqueca. RELATO DE CASO: Nosso objetivo foi descrever o caso de uma paciente jovem, com história de enxaqueca crônica sem aura, que apresentou agudamente midríase pupilar bilateral durante uma crise de enxaqueca, caracterizada como pupila tônica, e discutir as possíveis causas da midríase durante uma crise de enxaqueca. ataque de enxaqueca.

Orbital trauma and surgery are recognised aetiological factors of tonic pupil. Tonic or Adie's pupil is an efferent pupil defect in which light reactions to one or more segments of the iris sphincter are lost due to the postganglionic parasympathetic nerves damage from ciliary ganglion. There is loss of part or all of the light reflex and decrease in accommodative functions at near. We report a case of tonic pupil in a 42-year-lady after a successful surgical removal of an orbital cavernous haemangioma.

Objective To investigate the clinical manifestation, pathological features and pathogenesis of Holmes-Adie syndrome (HAS). Methods The clinical data of one HAS patient with sweating abnormality and combined with literatures were analysed. Results The patient had the typical characteristics of HAS, including Adie pupil, areflexia of lower limb and the symptoms of autonomic nerve dysfunction. The characteristic pupil of HAS was proved by slit lamp of ophthalmology. Cranial MRI showed lacunar infarction. A partial or total loss of neurons of the ciliary ganglion was the main pathological characteristic of HAS. Conclusions The etiology of HAS remains unclear, and has characteristic pupil finding, which was associated with autonomic nerve dysfunction to a certain extent. HAS still need to differentiate from Ross syndrome and Harlequin syndrome.
