Ultra Wide-Field Indocyanine Green Angiogram Highlights Choroidal Perfusion Delay Secondary to Giant Cell Arteritis.

Vision loss in giant cell arteritis (GCA) often presents as anterior ischemic optic neuropathy and central retinal artery occlusion. Previous studies have established an acute delay in choroidal perfusion on fluorescein angiography (FA) as a classic sign of GCA. The authors present a unique imaging case report of GCA where ultra wide-field (UWF) indocyanine green angiography (ICGA) offers improved characterization of delayed choroidal perfusion compared to FA. Routine use of ICGA, particularly UWF imaging, in patients with suspected GCA should be studied in a larger cohort to determine whether it may improve detection of choroidal perfusion delay.
