Abstract: Iris contour is relevant to a number of clinical situations including primary angle-closure (pupillary block and plateau iris) and pigment dispersion syndrome. Since iris contour is known to be affected by various phenomena such as prevention of blinking1, exercise2 and accomodation3,4, a method is needed to quantify the shape of the iris and allow comparison among individuals or under different conditions (e.g. before and after accommodation). The most commonly applied method is iris concavity as defined by Liebmann et al5 and illustrated in figure 1. A chord is drawn from the iris root to the posterior margin of the pupil. Next, the longest possible perpendicular line is drawn
