Comment on Central retinal artery and vein collapse pressure in giant cell arteritis vs non-arteritic anterior ischaemic optic neuropathy.

摘要

Jonas and Harder measured the central retinal artery and vein collapse pressure in two groups of patients with anterior ischaemic optic neuropathy (AION). The aim of the study was to evaluate the role of these-ophthalmodynamometric measures in differentiating an arteritic from a non-arteritic aetiology. The giant cell AION group entry criteria need some clarification. Did all patients exhibit the classic symptoms of giant cell arteritis (GCA) as well as elevated inflammatory markers and a positive temporal artery biopsy? When a patient presents with an AION and the classical features of GCA, the diagnosis is not usually challenging.
