Visual Involvement in Giant Cell Arteritis
Sponsor: ASST Fatebenefratelli Sacco
Summary
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.

Conditions
Interventions
Fluorescein and Indocyanine green Angiography
The ophthalmologist frequently recommends fluorescein (FAG) and indocyanine green angiography (ICGA) at baseline (T0) to evaluate retinal and choroidal vascularisation. They can be repeated also after 48-72 hours (T1), 7 ± 2 days (T2), 4 ± 1 weeks (T3), 12 ± 2 weeks (T4) or 26 ± 2 weeks (T5).
High-resolution Optical Coherence Tomography
The ophthalmologist often suggests performing HR-OCT initially (T0) to assess the width of the macula and optic nerve with potential signs of ischemic lesions in these areas. This assessment can also be repeated after 48-72 hours (T1), 7 ± 2 days (T2), 4 ± 1 weeks (T3), 12 ± 2 weeks (T4), or 26 ± 2 weeks (T5).
Angio-Optical Coherence Tomography
The ophthalmologist often suggests OCT-A at the beginning (T0) to assess the retinal and choroidal vascularization. These tests can also be done after 48-72 hours (T1), 7 ± 2 days (T2), 4 ± 1 weeks (T3), 12 ± 2 weeks (T4), or 26 ± 2 weeks (T5).
