Visual Involvement in Giant Cell Arteritis

This observational study aims to enhance the description of the different ways Giant Cell Arteritis (GCA) affects vision. The latest technology and knowledge are used to improve how we diagnose and predict patient outcomes. GCA is the most frequent vasculitis, an inflammation of vessels, in older adults. It involves large and medium-sized arteries and causes ischemic alterations such as stroke and blindness, through damage of extracranial arteries. The primary objective is to compare the frequency of the various ocular findings between the main alterations of arteritic and non-arteritic aetiology, such as Arteritic Anterior Ischemic Optic Neuropathy (A-AION) Vs. Non-Arteritic Anterior Ischemic Optic Neuropathy (NA-AION) or Central Retinal Artery Occlusion (CRAO) from GCA Vs. from other causes, through a comprehensive clinical and instrumental evaluation.
