Aqueous flare and choroidal thickness in patients with chronic hepatitis C virus infection

Purpose To investigate the status of blood-aqueous barrier and to evaluate the subfoveal choroidal thickness (SCT) in patients with chronic never treated hepatitis C virus (HCV) infection without any anterior or posterior ocular disease. Methods A total of 80 eyes of 20 naive HCV patients (M:F=12:8; mean age: 46.9±7.23 years) and 20 healthy controls (M:F=10:10; mean age: 48.2±8.71) were examined. Partecipants underwent a complete ophthalmologic examination. Aqueous flare was objectively quantified by using the non-invasive laser flare cell meter FC 1000 (Kowa, Tokyo, Japan), while SCT was evaluated by using enhanced depth imaging optical coherence tomography (Spectralis OCT; Heidelberg Engineering GmbH). An unpaired t test with Welch correction was performed to compare flare values and SCT between HCV patients and controls, considering significance a p
