| Sumario: | Ling Bei,1 Iris Lee,2 Michael S Lee,3 Greg P Van Stavern,1 Collin M McClelland3 1Department of Ophthalmology and Visual Neurosciences, Washington University School of Medicine, St Louis, MO, 2Casey Eye Institute, Oregon Health and Science University, Portland, OR, 3Department of Ophthalmology and Visual Neurosciences, University of Minnesota, Minneapolis, MN, USA Abstract: Giant-cell arteritis (GCA) is a visually devastating disease that often progresses to severe bilateral vision loss if untreated. Diagnosis of GCA is made challenging by the protean nature of the disease and the lack of a simple test that is both highly sensitive and specific. Choroidal filling delay on fluorescein angiography (FA) has been touted as a highly characteristic feature of GCA-related vision loss, although knowledge of both the sensitivity and specificity of this finding remains unproven. We report our experience of delayed choroidal filling on FA in a series of seven patients referred to an academic neuro-ophthalmology practice due to concern for GCA. Despite the FA findings, our examination, diagnostic testing, and long-term follow-up excluded the diagnosis of GCA in all cases, suggesting that choroidal perfusion abnormalities may occur in the absence of GCA. When evaluating a patient for acute vision loss, the astute clinician must remain cognizant of the limitations of FA in the diagnosis of GCA.Keywords: giant-cell arteritis, fluorescein angiography, delayed choroidal filling |
