Summary
Highlights
Billy introduces himself and the purpose of the video: to check for direct and consensual light reflex. He mentions that the room lights will be dimmed for the test.
Billy explains the procedure for checking direct light reflex. He uses a pen light, shining it into each eye individually and observing the pupil's constriction. He demonstrates by shining the light into the left eye, observing constriction, and then into the right eye, observing its constriction.
Next, Billy demonstrates checking for consensual light reflex, which ensures both eyes function properly together. To do this, he places his hand in the center of the person's forehead to isolate each eye. He shines the light into the left eye while observing if the right eye constricts, then reverses the process by shining the light into the right eye and observing the left eye's constriction.
