Steeper Iris Conicity Is Related to a Shallower Anterior Chamber: The Gutenberg Health Study

Figure 1

Illustration of iris conicity measurement. The iris surface is approximated by linear slopes (orange line). For illustration purposes, iris conicity is demonstrated. The opposite anterior chamber angles are connected by a plane (yellow line). Iris conicity is defined as the angle beta between these two lines. This corresponds to Pentacam “iris convexity” measure. Pentacam “iris convexity” is defined as half of the intersection angle of the linear slopes through the anterior surface of opposite iris cross-sections.
