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 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 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 کاملAssessment of pupillary light reflex using a smartphone application
In unconscious patients, pupillary light reflex is an indicator of brain damage. In the current study, a smartphone application was developed for the purpose of measuring pupillary light reflex with an aim to determine the agreement between pupillary light reflex measurements using a smartphone application (APP) and a penlight (PEN). The APP acquires five sequential photographs using the camera...
متن کاملThe Pupillary Light Reflex in Idiopathic Intracranial Hypertension
PURPOSE To evaluate the effects of idiopathic intracranial hypertension (IIH) on rod-, cone-, and melanopsin-mediated pupillary light reflexes (PLRs). METHODS Pupillary light reflexes elicited by full-field, brief-flash stimuli were recorded in 13 IIH patients and 13 normal controls. Subjects were dark-adapted for 10 minutes and the PLR was recorded in response to short-wavelength flashes (0....
