    A 28-year-old man was admitted following a road traffic accident with a Glasgow Coma Score (GCS) of 3/15 and fixed pupils.[ncbi.nlm.nih.gov] Reflexes include pupillary response (fixed pupils), oculocephalic reflex, corneal reflex, no response to the caloric reflex test, and no spontaneous respirations.[en.wikipedia.org] On day three his Glasgow Coma Scale score was 3/15, with fixed dilated pupils.[ncbi.nlm.nih.gov]

An ICP bolt was inserted (opening pressure 50 mm Hg; Figure ).[stroke.ahajournals.org]

  • Botulism

    Less than 50% of patients have dilated or fixed pupils. Neurological deficits are symmetrical, and heart rate is normal.[web.archive.org] Therefore, the classical diagnostic pentad of botulism (dry mouth, nausea, vomiting, dysphagia, diplopia, fixed dilated pupils) may be of limited sensitivity in single cases[ncbi.nlm.nih.gov] pupils Extremely dry mouth unrelieved by drinking fluids Generally, botulism progresses as follows: Preceding or following the onset of paralysis are nonspecific findings[emedicine.com]

  • Multisystemic Smooth Muscle Dysfunction Syndrome

    Congenital fixed dilated pupils (congenital mydriasis) is characterized by hypoplasia or aplasia of the iris muscles, with absence of iris between the collarette and pupillary[ncbi.nlm.nih.gov] Home Catalog Congenital fixed dilated pupils due to ACTA2-mu... article Congenital fixed dilated pupils due to ACTA2-multisystemic smooth muscle dysfunction syndrome Françoise[lib.ugent.be] Congenital fixed dilated pupils due to ACTA2- multisystemic smooth muscle dysfunction syndrome.[search.bvsalud.org]

  • Aniridia-Cerebellar Ataxia-Intellectual Disability Syndrome

    The combination of muscular hypotonia and fixed dilated pupils in infancy is suspicious of Gillespie syndrome.[ncbi.nlm.nih.gov] The typical presentation is based on fixed dilated pupils in a hypotonic child. Iris abnormalities distinguish GS from other forms of aniridia.[ncbi.nlm.nih.gov] The typical presentation is the discovery of fixed dilated pupils in a hypotonic infant. The iris abnormality is specific and seems pathognomonic of Gillespie syndrome.[ncbi.nlm.nih.gov]

  • Hyperventilation

    Only if active seizures, or signs of transtentorial herniation such as fixed or asymmetric pupils, neurologic posturing (decerebrate or decorticate), Cushing's reflex (hypertension[health.ny.gov]

  • Sinusitis

    In addition, the pupil may be fixed and dilated. Although symptoms usually begin on one side of the head, the process usually spreads to both sides. Brain Infection.[web.archive.org]
