    The 4th semester student was performing a physical examination of a 19‑year‑old female patient from Portsmouth who was troubled by a problem with cranial nerve dysfunction. The student first asked the patient to turn her head to the left, and look to the left. She‑then gently touched the limbus of the patient's right eye with a little bit of cotton. As she touched the eye, she observed that the patient's right eye blinked, but the left one didn't. She then repeated the procedure, having the young woman turn her head and her eyes to the right, while the student stroked the left limbus. Now, she noted that the right eye blinked, but the left one did not. She correctly deduced from her observations that ...
