Fig. 4 Normal angle vessels. Blood vessels may normally be visible in the angle. It is imperative to differentiate normal from abnormal angle vessels. The normal angle has three types of vessels: (1) circular ciliary body band vessels; (2) radial iris vessels; and (3) radial ciliary body band vessels. This is an example of a circular ciliary body band vessel. It is completely normal and the most common of the three types. If angle vessel that bridges the scleral spur is seen, it is probably abnormal.
