Forty\u2010five\u2010degree fundus images of both dilated eyes were acquired with a fundus camera (Canon CR\u20102, Tokyo, Japan). The summary diameter of the arterial retinal vessels (central retinal artery equivalent, CRAE), venous retinal vessels (central retinal vein equivalent, CRVE), vascular tortuosity and fractal dimension (FD) were measured using VAMPIRE software. Retinal vasculitis was characterized using fluorescein angiography and active choroiditis using indocyanine green angiography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At baseline, BSCR was associated with lower FD compared with matched controls (mean difference, \u22120.04; 95% confidence interval [CI], \u22120.06 to \u22120.02, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). No other VAMPIRE parameters (CRAE, CRVE, arterial and venous tortuosity) differed. Among BSCR patients, retinal vein vasculitis was associated with higher CRAE (mean difference, 21\u2009\u03bc; 95% CI, 2.6\u201340, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.03), venous tortuosity (geometric mean ratio, 1.79; 95% CI, 1.18\u20132.72, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.007) and FD (mean difference, \u22120.04; 95% CI, \u22120.06 to \u22120.01, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.007). Resolution of retinal vein vasculitis during follow\u2010up was paralleled by decrease in CRAE, CRVE and venous tortuosity values and increase in venous FD, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>BSCR is associated with lower FD value, suggesting that chronic retinal inflammation induces microvascular remodelling. Efficient treatment of retinal vasculitis may reverse changes in retinal vascular parameters.
