Objective:
To determine whether the diagnostic sensitivity of bilateral temporal artery biopsy is superior to that of unilateral biopsy in cases of suspected temporal arteritis.
Materials And Methods:
A retrospective analysis of the results of 60 bilateral temporal artery biopsies examined in an ophthalmic pathology laboratory.
Results:
The histopathologic diagnosis in 13% of the biopsy pairs was discordant. There was a 5% chance of obtaining a positive biopsy result on the side opposite an initially negative biopsy result.
Conclusions:
Bilateral temporal artery biopsy is 5% more likely than unilateral biopsy to detect the characteristic histopathologic findings in patients with temporal arteritis.
