Answer

GCA should be considered in elderly patients presenting with vision loss. Many authors advocate the liberal performance of temporal artery biopsy since the risk of permanent vision loss due to a missed GCA diagnosis outweighs the risks associated with biopsy. Diagnostic prediction models can help guide the decision for temporal artery biopsy but should be used in conjunction with clinical judgment. [32] In centers with radiologic expertise and high-quality imaging, tests such as Doppler ultrasonography of the temporal artery may be considered.
