What is Hippus?

Hippus, also known as pupillary athetosis, is spasmodic, recurrent oscillation in the size of the pupil, with alternating narrowing and dilation of the pupil's diameter of about 1 to 2 millimeters (0.03 to 0.07 inches) every five seconds, without relation to the ambient, patient or focus length. Normally pupils limit when the examiner moves the light into the eye or when the patient focuses on a nearby object. Pupils dilate when the subject feels enthusiastic or emotionally excited. Doctors consider hippus a normal change in pupils' response, and in most cases HIPPUS does not mean a basic disease or defect. In rare incidents, however, this form of pupillary variability can point to systemic disease or toxicity, which may be life -threatening.

Scientists have analyzed cases of hospitalized patients with established hippus for comparison with patients without hippus. Patients who have exposed hippus have experienced a greater Chance of dying over the next 30 days than control patients. ProbableThe dying within 30 days increased when patients had a change in mental condition, kidney disease, liver cirrhosis and a history of trauma. Hippus was another independent risk factor that statistically increased the risk of death even in the absence of other factors. For this reason, pupillary atetosis may expose them to a higher risk of premature death in patients with hospital.

scientists have combined hippus with various diseases, including multiple sclerosis, neurosyphalis, myasthenia gravis and brain tumors. The oscillating pupil may also occur in conjunction with the overall third skull of the third skull, an oculomotor nerve that disrupts the supply of nerve to the muscles that move the pupil and the eye itself. Patients with an imbalance of autonomic nervous system also develop pupillary athetsje. In addition to checking the size of the pupil, the autonomous nervous system is controlled by heart rate, salivation, urination, breathing and organ function.

hippus occursWhen the patient used one of the barbiturate drugs. Pentobarbital, Fenobarbital, Bulbibol and Thiopental are some of the common drugs that patients use for medicinal or recreational purposes that can cause condition. When police officers stop the lawsuit for suspicion of behavior within the behavior of influence (DUI), they routinely check the pupils on the abnormal size of pupils or oscillations. Abnormally small pupils may indicate the use of narcotics, abnormally expansion pupils may indicate the use of cocaine and hippus may indicate the use of sedatives.

Hippus can also be a sign of Aconite or MonkShood poisoning. In traditional Chinese medicine, doctors prescribe Aconite to cure the lack of energy and cold, the so -called yang deficiency. Ayurvedic healers also use it to treat cold or fever.
