6. External examination. Look for any ptosis by measuring the margin-to-reflex distance, which is the distance from the corneal light reflex to the margin of the upper lid. Look for lagophthalmos. Note any unusual growths or lesions that may require a biopsy. Palpate lymph nodes and the temporal artery if indicated by the history or exam.To test the VOR reliably, it is important to determine that other types of eye movements are normal for two reasons. First, proper interpretation of the VOR responses depends on intact eye movements. Second, abnormalities of eye movements can themselves be useful in localizing neurologic abnormalities.
