SonoApp: Ocular US – “Blinded by the light!” – Pupillary Constriction

THIS is truly my fav when it come to US applications. If you ever show this to any group of students or other learners, the entre room responds with , “Oooooooh, Awwwww.” You can see pupillary constriction by angling the probe upward to get a coronal view of the eye and shining a light on the eye – or the opposite eye. Or, you can decrease your depth and have the linear probe directly on the eyelid in transverse view while the patient looks upward. You will see the linear muscle layers which will constrict when a light is shined in the opposite eye (as seen below) … Pretty cool stuff, I tell ya….
