Iris concavity/convexity. Iris configuration is determined first by creating a line from the most peripheral to the most central points of iris pigment epithelium. A perpendicular line is then extended from this line to the iris pigment epithelium at the point of greatest concavity or convexity. (A) Iris convexity measurement (arrow). (B) Iris concavity measurement (arrow).
