The consultants and specialty society members agree that
magnetic resonance imaging may be useful to detect causes of
visual loss other than ION and CRAO (e.g., cortical blindness,
pituitary apoplexy). All groups agree that a high-risk
patient’s vision should be assessed when the patient becomes
alert. The consultants and specialty society members agree
that, in high-risk patients for whom ION is suspected, hemoglobin
or hematocrit values should be adjusted upward,
blood pressure should be increased, and oxygen should be
administered.
