artery biopsy is a key element in the diagnosis of anterior ischemic
optic neuropathy (AION).
arteritic anterior ischemic optic neuropathy may lead to bilateral,
irreversible blindness in a short period of time.
is permissible to begin treating patients with suspected (AION)
while awaiting the results of the temporal artery biopsy. We regard
the temporal artery biopsy as a medical emergency, and efforts are
made to process tissue on the same day of receipt (if the tissue
arrives in the laboratory before 9:30 AM, a final diagnosis based
on permanent sections is usually possible by later the same afternoon).
