Sonographic Consensual Pupillary Reflex
Patients suffering from severe orbital trauma are at risk for numerous complications, including orbital compartment syndromes. This can result in an afferent pupillary defect, which must be evaluated for on physical examination. Unfortunately, these at-risk patients are often challenging to examine properly due to surrounding edema. Point-of-care ultrasonography can be used as an adjunct to the...
متن کاملConsensual pupillary light reflex in the pigmented rat.
We measured the pupillary light reflex (PLR) in 5 pigmented, Long Evans rats (under urethan sedation) in three conditions: direct stimulation, consensual stimulation, and a control condition designed to measure the effects of stray light. The average constriction (maximal amplitude) produced by a ganzfeld stimulus delivering 1.6 log quanta absorbed per rod per sec for a duration of 3 sec was me...
متن کاملA true neuronal consensual pupillary reflex in chicks
The existence of a true neuronal consensual pupillary reflex (CPR) in birds has long been debated. In this century Noll (Noll, A. (1915). Archiv für Physiologie (Leipzig), 350-372.) claimed to observe a neuronal CPR in a pigeon, but this was contradicted by Levine (Levine, J. (1955). Science, 122, 699.), who observed a direct transillumination effect (Durchleuchtungs-effekt) due to the retinas ...
متن کاملThe pupillary light reflex in normal subjects.
In 19 normal subjects the pupillary reflex to light was studied over a range of stimulus intensities by infrared electronic pupillography and analysed by a computer technique. Increasing stimulus intensity was associated with an increase in direct light reflex amplitude and maximum rate of constriction and redilatation. Latency from stimulus to onset of response-decreased with increasing stimul...
متن کاملSystem for measurement of the consensual pupil light reflex
The paper presents the measurement system for quantitative investigation into the consensual reaction of pupil to light. This reaction is called the pupil light reflex (PLR). The system enables the recording and analysis of the time characteristics of pupil radius variation during PLR. In the measurement the stimulating light is projected on the left eye in so-called Maxwellian projection but t...
