Comparison of retinal vascular abnormalities in the fellow eyes of children with Coats’ disease and normal subjects using ultra-widefield fundus fluorescein angiography

Because Optos® UWFFA device is able to quickly take panoramic fundus images using mild excitation light without contacting the cornea, it allows the detection of peripheral vascular changes in the fellow eyes of children with Coats' disease. Contrary to the previous belief that Coats' disease is a "unilateral condition", our finding shows that Coats' disease appears to be a highly asymmetric bilateral disease, and the peripheral vascular abnormalities in the fellow eye remains stable in short term.
