Question:

Please explain the difference between the Eyes exam bullet and the bullet for the exam of cranial nerves 3, 4 and 6.

Answer:

The exam element for the Eyes states “Ophthalmoscopic examination of optic discs (e.g., size, C/D ratio, appearance) and posterior segments (e.g., vessel changes, exudates, hemorrhages).” This requires use of an ophthalmoscope and examination of the posterior segments including the optic discs.

Exam of cranial nerves 3, 4 and 6 does not require the use of an ophthalmoscope. Rather, the neurosurgeon observes eye movements and the pupils to determine cranial nerve function.
