The images were quantitatively and qualitatively analysed and compared with healthy controls.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eighty-six eyes of 56 patients with posterior uveitis (mean age 45.2\u00b119.9 years; 58.9% female), and 38 eyes of 19 age-matched healthy controls (57.9% female) were included. The mean perfusion density (PD) in 3\u00d73 mm and 12\u00d712 mm CC scans was significantly lower in eyes with posterior uveitis compared with those of healthy controls. However, no significant difference in the mean PD of choroidal scans was found comparing eyes with posterior uveitis and healthy controls. The mean PD in eyes with active disease was significantly higher compared with the inactive eyes on 12\u00d712 mm choroidal scans (55.61% vs 51.25%, p=0.02), while no difference was found in the CC slabs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>CC and choroidal assessment using OCTA provides useful information in patients with posterior uveitis.
