Direct And Indirect Pupillary Light Reflex. The plrl was measured at both photopic and scotopic illuminance level using an infrared lig. The pupillary light reflex plr is the constriction of the pupil that is elicited by an increase in illumination of the retina.
The pupillary light reflex plr is the constriction of the pupil that is elicited by an increase in illumination of the retina. In 46 patients with definite multiple sclerosis ms the direct and indirect pupillary light reflex latency plrl and visual evoked potential vep latency of the p100 were measured for each eye separately. The pupillary light reflex plr is the constriction of the pupil that is elicited by an increase in illumination of the retina.
The pupillary light reflex plr is the constriction of the pupil that is elicited by an increase in illumination of the retina.
The pupillary light reflex plr or photopupillary reflex is a reflex that controls the diameter of the pupil in response to the intensity of light that falls on the retinal ganglion cells of the retina in the back of the eye thereby assisting in adaptation of vision to various levels of lightness darkness. Via the direct and indirect pupillary light reflexes. This is mediated by. A greater intensity of light causes the pupil to constrict miosis myosis.
