Clinical Reasoning: A 22-year-old man with diplopia
A 22-year-old previously healthy man presented to an ophthalmology clinic with binocular horizontal diplopia. He had recently traveled to the main island of Hawaii. About 2 weeks after returning home, he developed a severe headache with associated fever, emesis, photophobia, phonophobia, and neck stiffness. He also reported a sensation of pressure in his left eye and both ears but denied any pulsatile tinnitus or transient vision loss. Over the next 2 weeks, his headaches worsened, causing him to wake up frequently in the night. He then developed horizontal diplopia that was worse at a distance and was referred to the neuro-ophthalmology clinic.
