Temporal Artery Imaging in Suspected Giant Cell Arteritis using the SPECTRALIS OCT FLEX Module

Diagnosing Giant Cell Arteritis (GCA), which causes cranial ischaemic symptoms such as sudden and permanent loss of vision, is challenging. Definitive diagnosis is by using a combination of clinical history and confirmative test such as temporal artery biopsy (TAB), or ultrasound that requires specialist skills. It is recognized that a reliable and non-invasive test is needed. The aim was to assess the feasibility of spectral domain Optical Coherence Tomography (OCT) to visualize the superficial temporal artery (STA) in vivo and ex vivo.
